The Eyes Have It: Clues from Vitreous Humor at Autopsy

When it comes to laboratory testing at autopsy, our options are limited compared to those for living patients. We’ve previously discussed the complexities of postmortem toxicology testing (https://labmedicineblog.com/2023/05/23/toxicology-and-forensic-pathology-more-than-a-numbers-game/) but even basic laboratory studies like a glucose or sodium level cannot be reliably measured from postmortem serum specimens. Upon death, hemolysis and cellular breakdown rapidly set in; as tissue oxygen stores and ATP are depleted, the careful balance of intracellular and extracellular electrolytes is lost, making serum essentially useless as an analyte. This makes potentially lethal conditions which leave only non-specific clues (like diabetic ketoacidosis, dehydration, or hyponatremia) difficult or impossible to prove postmortem. Fortunately at autopsy we can access a unique, relatively protected body fluid which cannot be obtained from living patients- the vitreous humor.

Vitreous humor is the clear, thick fluid which fills the globe of the eye. It is nearly acellular, composed predominantly of water with admixed hyaluronic acid and collagen proteins, and its insulated location provides it relative protection from the effects of decomposition and hemolysis. Vitreous humor is typically collected it at the beginning of an autopsy by inserting a needle into the most lateral aspect of the eye and aspirating the fluid; using this method, one can avoid collecting bits of retina (which interfere with analysis of the sample), and avoid creating any noticeable puncture marks or hemorrhages.

Years of data have shown that vitreous fluid approximates serum levels of major electrolytes, glucose, urea nitrogen (VUN), creatinine, ketones, and ethanol. Vitreous fluid is also valuable in the detection of 6-monoacetylmorphine (6-MAM), a metabolite of heroin which is quickly metabolized to morphine in the blood. Identifying 6-MAM in vitreous fluid allows us to ascertain a decedent used heroin, rather than just morphine.

While vitreous fluid is less affected by decomposition, it is not completely immune. The changes are predictable, though, and learning these patterns prevents misinterpretation of decomposition changes, and allows the pathologist to identify which results are still meaningful.

Vitreous fluid potassium will increase with the postmortem interval – in fact, this electrolyte is often touted (erroneously) as a method to determine time of death. Unfortunately there are many other variables (for example, antemortem potassium levels and rate of decomposition) affecting the rise of vitreous potassium, and this method has not proven to be the “holy grail” many were hoping for.

In contrast, vitreous sodium, chloride, and glucose levels all decrease following death – so while a low level may just be an artifact, a high level can be very meaningful. Even “low” levels should be assessed in the clinical context of the case and the concomitant potassium level. If the potassium is normal or barely elevated, it’s unlikely a “low” value is just decomposition-related.

Vitreous humor poses some challenges in the laboratory, though. Because of the thick, viscous nature of the fluid, it can be challenging to actually run it through the instrument. As decomposition progresses, the eyes can desiccate and make the vitreous humor even thicker. In cases of eye trauma, intraocular hemorrhage can contaminate the vitreous humor as well. Importantly, in situations of suspected head trauma in infants, the recovery of vitreous fluid is deferred until the end of the autopsy. Retinal and optic nerve hemorrhages are usually not identified until the brain is removed, and we need to be sure that any trauma we identify was not created artificially during the autopsy.

In summary, the use of vitreous humor as an analyte is a great illustration of creative problem solving. At autopsy the quality of blood specimens is limited, but we aren’t limited to blood. This lesson can be translated to any area of the laboratory: thinking outside of the proverbial box can lead to unexpected, paradigm-shifting opportunities.

The Impact of ASCPi Certification

The world of medicine relies heavily on the skilled and knowledgeable hands of medical laboratory scientists. However, with globalization and a growing healthcare workforce, ensuring internationally trained scientists can seamlessly integrate into new environments is more critical and challenging than ever.

For laboratory scientists in developing countries, obtaining certification can be a life-changing event. Beyond the simple struggles of daily living, these individuals must overcome the obstacles and difficulties that students in the U.S. rarely (if ever) have to face. Yet still, they seek to prove their knowledge and worthiness by seeking international certification.

ASCP is at the forefront of certifying laboratory scientists in developing countries by offering the ASCPi exam. There are few opportunities for students in second and third-world countries to get the quality training and experience to pass the exam. These students come with diverse life experiences and needs but are still passionate about working in the lab.

I discussed the importance of the ASCPi certification with Marion Carrilo, MS, MLS (ASCP), the visionary founder of Trinity Blood Solutions in Trinidad and Tobago in the West Indies, about the reasons why and the need for certification and how the ASCPi is bridging the gap for international laboratory scientists.

Hi Marion, thanks for talking with me today. First, can you describe your typical student?

The typical individuals pursuing MLS ASCPi certification are experienced medical laboratory technologists/technicians. Many of them have worked in the field for at least five years. They love the profession and want more out of it.

In Trinity’s ASCPi Exam Prep, I get some MLTs who have never done an MLT program but want the theory so they can get up to speed with their colleagues who completed an MLT program. These are not typical individuals and they usually have a degree in biological science and are practicing MLTs.

Why do the students choose to take the ASCPi exam?

Reasons for taking the ASCPi exam will vary according to the region and according to the state of affairs for medical laboratory technologists. In many countries, taking and passing the MLS ASCPi is the first step to migrating to the USA as a medical laboratory tech. People migrate due to poor salaries, bad working conditions, and no or limited opportunities to advance in the profession.

In the Caribbean, taking the MLS ASCPi exam after graduating from an MLT program is not routine. Every country has its criteria for being able to practice in a medical laboratory, and in many cases, it is sufficient to graduate from a local MLT program and/or be registered with a local MLT association or board. ASCP is not yet a household name in the Caribbean, so many who pursue taking the exam do it to migrate. Others take the exam for professional advancement.

Migration to the U.S. or another developed country provides them with better opportunities for professional and personal development. In the U.S., the pathway to professional advancement is sure if you work hard. In developing nations, working hard does not guarantee good success.

Professional advancement can be a promotion to a supervisory role or being able to show the credentials of international certification. In some cases, medical laboratory technologists may have been encouraged to get certified by another colleague who is ASCPi certified.

What are the benefits to the lab of having ASCPi techs?

Whether an individual prepares for the exam on their own or enroll in an exam preparation course, they are exposed to systems and procedures not used in their country. This new exposure encourages those techs to be more conscientious in their practice. Having ASCPi techs helps to maintain laboratory accreditation because the new knowledge now gives them an appreciation for working in quality systems. It also encourages the certified tech to share what they learned through preparation with their colleagues.

What do you think the ACSP should or would like them to do to help international students achieve certification?

Recently, a certified individual told me that making the BOC page more intuitive for international candidates will make ASCPi certification info easier to find and understand.

This never occurred to me because I’ve used it for so long. I agree that the BOC page can be intimidating. An example would be displaying the routes in a table form as opposed to the drop-down menus. Have a dedicated page with only the necessary information for the international candidate. So removing newsletter, BOC eligibility Assistant, Categories of certification etc., U.S certification.

Last month, ASCPi BOC created a new Caribbean Advocacy Team. This team will help to provide ASCP BOC with information about how they can best promote certification in the region. As mentioned before, each region has a specific culture concerning the profession, so having Advocacy Teams in various regions is a great gesture.

I really appreciate you providing your experience with our readers. Do you have any final thoughts you would like to share?

It is a great feeling to know ASCP BOC is providing opportunities for techs to advance globally. Some may say they are contributing to the brain drain of a country, and I’m afraid I have to disagree. Instead, they are providing opportunities for advancement as a tech that are not available in the international candidate’s country.

Migration is an expensive process, so not everyone who becomes certified will leave, although they may have planned to do so initially. Even those who leave may return and help their country or provide assistance to their home country from their new home abroad.

Advancement cannot only be seen as moving up a career ladder; it must be seen holistically. A tech working 12 hours 6 days per week and not being paid enough to provide a reasonable level of comfort for their family stymies the work that tech will do and their mindset about the profession. ASCPi provides a way for these techs to move out of such systems and advance holistically in a profession they love.

The ASCP is doing its part to ensure that there are well-trained medical scientists in the world’s laboratories who can provide accurate and timely results for patient care. Passing the ASCPi exam can be, and has been, a life-changing event for scientists working under the most stressful life conditions worldwide. By bridging the knowledge gap and fostering a culture of excellence, the ASCPi is paving the way for a brighter future in laboratory medicine throughout the world, one well-equipped scientist at a time.

Microbiology Case Study: A 53 Year Old Male with Malaise, Bilateral Flank Pain and Decreased Urine Output

Case History

A 53 year old male presented to the emergency department with a one-day history of malaise, bilateral flank pain and decreased urine output. His past medical history was notable for decompensated cirrhosis due to alcohol use disorder complicated by esophageal varices and gastric ulcers, peritoneal ascites, several recent episodes of upper GI bleeding, monoclonal gammopathy of unknown significance, and remote prostate cancer status post prostatectomy. Oral history indicated the patient was actively drinking shortly before presentation and had recently consumed oysters on the half shell, broiled shrimp, and crab meat. While being seen in the emergency department, the patient quickly progressed to septic shock.

Admission laboratory studies demonstrated severe metabolic acidosis, pancytopenia, and acute renal failure. Initial CT abdomen/pelvis demonstrated cirrhotic liver changes, varices, distal esophageal wall thickening, bilateral perinephric fat stranding extending into the pelvis and perivesical fat. The patient was admitted to the MICU for intubation/mechanical ventilation and administration of multiple pressors, as well as empiric meropenem, vancomycin and micafungin given concern for septic shock.Initial blood cultures drawn in the ED flagged positive with gram negative rods (both aerobic and anaerobic bottles) less than 24 hours after collection.

Laboratory Identification

Blood cultures were processed for culture workup and molecular identification. No identification was able to be established using a commercial multiplex PCR-based molecular panel on the positive blood culture broth. Subsequent growth of the organism on MacConkey agar 18 hours later revealed non-lactose fermenting colonies (Image 1A). The organism was oxidase-negative, positive for catalase and indole (Image 1B) and exhibited hydrogen sulfide production when inoculated on triple sugar iron (TSI) media. The organism was definitively identified as Edwardsiella tarda by MALDI-TOF MS and was broadly susceptible to all antibiotic tested including beta-lactams and fluoroquinolones.

Discussion

Edwardsiella tarda is an infrequently isolated member of the Enterobacterales which is most often associated with gastroenteritis. Reports of additional presentations include peritonitis, intra-abdominal abscess, and wound infections are increasing.¹ Bacteremia is rare, and can lead to cholangitis, cholecystitis, and liver abscess via hematogenous spread. Patients of advanced age (>65 years) and those with hepatobiliary diseases including liver cirrhosis and alcohol abuse and iron storage disorders are at increased risk for extraintestinal disease.^.2 Colonization of the gastrointestinal tract is believed to be a precipitating even leading to bacteremia. Cases of gastroenteritis are usually self-limiting, although ciprofloxacin or trimethoprim/sulfamethoxazole can be utilized in cases of prolonged duration.⁵ Prompt and accurate diagnosis of E. tarda bacteremia is important as this presentation is associated with an elevated mortality rate,⁴ particularly among those with liver disease.

As members of the Enterobacterales, Edwardsiella sp. share common biochemical features of other members of the order including being catalase-positive and oxidase-negative. Oxidase negativity aids in the distinction between E. tarda and Aeromonas/Plesiomonas, both species which are also associated with aquatic environments and cause gastrointestinal infections.⁵ E. tarda is non-lactose fermenting and reduces sulfur containing amino acids to hydrogen sulfide. This can result in confusion with members of the genus Salmonella⁴ as colonies exhibit similar appearances on medias including Hektoen Enteric agar and Xylose-lysine deoxycholate agar formulated for recovery and presumptive identification of Salmonella from gastrointestinal specimens. Importantly, E. tarda is also indole-positive which will biochemically differentiate these two genera.

E. tarda is associated with freshwater or brackish aquatic environments. This organism is a well-known pathogen in aquaculture industries causing serious infections in fish and significant economic loss. As such, vaccines and prophylactic antibiotics are utilized to prevent E. tarda infection among aquatic animals, and diagnostic approaches including specialized multiplex PCRs are available. Human infection is often associated with consumption of contaminated fish and seafood, and diagnosis is almost exclusively dependent on microbiological culture by contrast. Clinical multiplex molecular panels for both gastrointestinal and bloodstream infections lack the ability to detect E. tarda. In this patient’s case, recent consumption of seafood serves as the most likely event leading to E. tarda gastrointestinal colonization and is consistent with previously reported cases of E. tarda bacteremia.³ The patient was treated with meropenem eventually narrowed to piperacillin/tazobactam and blood cultures cleared. He was weaned off pressors and extubated. Unfortunately, the patient decompensated over the course of three weeks due to worsening shock and acidosis. He was moved to comfort care and expired soon thereafter.

Happy Medical laboratory Professionals Week! A Trip Down Memory Lane

When I think of Lab Week, I think of all the Lab Week celebrations we’ve had in the past: Food, games, from “Guess whose baby picture?” to word searches and coworker trivia, and of course, more food. I’ve seen the same games over and over, but with new coworkers they’re always fun. Probably the most unique game I’ve seen, was “whose sample is this?” Smushed chocolate candy bars were stuffed into sample cups (and looked like you know what) and we had to guess which ‘sample’ came from which candy bar. Lab week also helps us remember the techs we’ve worked with in the past and the good times we’ve had in the lab and outside. And, of course, Lab week always seems to bring up reminiscing, and the question “Remember when?”

As a nod to lab week, I’d like to take you on a little trip down memory lane. Those of us who have been around for a while can laugh and add our own stories. The new techs in the lab, the younger generation will look at us and say “No way!”” or “You’re joking, right?”

I work in a lab that is very fortunate to have a few wonderful techs in their late 60’s and 70’s who still work for us part time. But anyone who has passed through our lab in the past 60 years remembers Irene, who is over 80, and has been here since 1963. That’s before many of us were born! Now Irene doesn’t work every day, or even every month, but she’s there for our students and newly graduated employees when we can use her talents for a few days. She has boxes full of teaching slides and comes in to review WBCs and RBC morphology with them and shares many stories about ‘the old days’ in the lab. Recently she was talking to a new grad and mentioned the old lab and the rabbits they kept in the lab.

“Rabbits?’ he asked.

“Yes, youngster, let me tell you about it.”

Rabbits were used for the first pregnancy tests. The first HCG tests came out in the early 1970’s, but before then, the question “Did the rabbit die?” was associated with a positive pregnancy test. Young rabbits were injected with urine or blood from a woman, and several days later, the animals were dissected to look for enlarged ovaries, a sign that HCG was present in the injected specimen, and a positive pregnancy test. So, in reality the rabbit (or mouse, or frog) always died, whether the woman was pregnant or not.

I fortunately missed the live animals in the lab era. Now that I’m working with techs who are younger than my kids (and not that much older than my grandkids!), when us ‘old timers’ talk about what the lab used to be like, we get incredulous wide-eyed stares.

“You didn’t wear gloves??”

“They drank coffee in the lab?”

“No computers?”

In my very first job out of college I worked in a hospital lab, and trained in Hematology, Chemistry and Blood Bank. It was the time of the rise in automation, and we had some great ‘new’ analyzers. We had a Coulter S in hematology, the first automated hematology analyzer. The Coulter S offered 7 parameters. In about 1 minute it could analyze and report the WBC, RBC, Hgb, Hct, MCV. MCH and MCHC. Before this we had to prepare samples, lyse RBCs to count WBCs, perform hemoglobin measurement on a spectrophotometer, and calculate the indices! If a physician wanted a differential, we stained slides by hand and counted a 100-cell diff. Platelet count counts fortunately were not ordered on every CBC because those were counted manually!

I remember training in the chemistry department with a lot of instruments which each did only one or 2 tests. Individual tests were done on single test analyzers. Which meant a lot of techs in the lab, and you could be assigned to a bench where you did just Na and K on the flame photometer or just Glucoses and BUNs on single test analyzers all day. We did have a STAT analyzer which did electrolytes, glucose and BUN, and a larger analyzer that did 12 test panels, but they were only used when the full panels were ordered. These multi test analyzers were new and exciting, but in 1980 we were still uncapping and pouring off all our samples by hand. Without gloves!

“What?? No gloves?”

No gloves. We drew blood and worked in the lab with no gloves. Analyzers had glass coils that techs changed with their bare hands, and there were accidents. Techs contracted hepatitis and in the 1980’s the fear of contracting HIV was real. It wasn’t until 1992, when the Occupational Health and Safety Administration (OHSA) published the Bloodborne Pathogens Standard. There was increased awareness of HIV, and OHSA implemented universal precautions to protect workers who may come in contact with bodily fluids. OSHA’s standard required employers to provide personal protective equipment, including disposable gloves.

I once read an article that said that medical technician/technologists were the profession that drinks the most coffee. Now, I don’t know about that because I don’t drink coffee, but what they didn’t mention in the article was that they used to drink it in the lab! Yes, the cup of coffee often sat next to the microscope while doing diffs. And remember, no one wore gloves. I remember a doctor walking through the lab smoking a cigar. And while I don’t remember if I ever saw eating in the lab, I’m pretty sure it happened. These things are so taboo to us now that sometimes we wish we were camels because we often go for hours without a sip of water! We may have been the profession who drinks the most coffee, but today we may be the most dehydrated because the closest ‘clean ‘area to get a drink is way down the hall! And we’re too busy to leave our work and go get a drink!

People often use the term ‘The Good Old Days’ when talking about the past, but in the lab, these times weren’t always ‘good’. Yes, we had good times. But there were also practices that weren’t what we would today consider safe. Besides the lack of gloves, and coffee in the lab, there was also mouth pipetting. Remember spit strings? Techs kept them in their pockets for use in mouth pipetting body fluids (shudder). We washed glassware, even literally rinsing blood out of test tubes and reusing them.

We also love to reminisce about obsolete lab tests. I remember when AST, LDH and CK were used for markers of myocardial infarction. Then we had a new test, the CK-MB, which is now designated antiquated and has been replaced by cardiac troponin I for diagnosing MI. Bleeding times were once widely used as a platelet function test. Today this rather crude test is rarely used and not even offered by many labs. Glass in the lab has been replaced by plastics from vacutainer tubes and blood bags to graduated cylinders and beakers. We no longer count platelets on a hemocytometer because our automated analyzers perform platelet counts. In Urinalysis, we used to do confirmatory tests for glucose, bilirubin and protein in urine. And so many more tests that have been replaced by newer and better testing. What is your favorite or no so favorite ‘obsolete’ lab test?

We’ve certainly come a long way in the last 60 years! Lab Week is a great time to generate new awareness and excitement about the laboratory medicine profession while having some fun with your lab coworkers. Thanks to everyone who is part of the laboratory team for your hard work and dedication. Happy Laboratory professionals Week!

Violence in the Laboratory

The field of laboratory safety is very obviously about the protection and well-being of those who work within the labs. The topics of study within this field typically include chemical hygiene, biohazard safety, and even emergency management. One area of focus that historically has not been discussed under the lab safety umbrella, though, is workplace violence. Unfortunately, this topic definitely needs attention and a place among the other safety subjects.

Teaching laboratory staff how to recognize workplace violence (WVP) is important, and the activities that define acts of such aggression are numerous. The National Institute of Occupational Safety & Health (NIOSH) defines WVP as “any violent act, including physical assaults and threats of assault, directed toward team members at work or on duty and include physical injury, threats, abuse, hostility, harassment, discriminatory language/behavior and other forms of verbal violence that can potentially escalate to physical violence.”

The definition is important so staff can identify it, respond to it, and report it. A higher priority, however, is not only to learn the tools that will help staff recognize when potential threats at work arise, but to also be able to de-escalate a tense situations and mitigate any violence altogether. Teach laboratorians to pay attention signs of aggression such as disruptions, outbursts, throwing objects or threatening gestures.

Employees should be taught to respond to growing violence threats by remaining calm, listening, and by demonstrating empathy. Responding to people by yelling or getting into their personal space will only escalate the situation. Your tone of voice, the volume of your voice, your facial expressions and your posture all give signals to the person who is agitated, and if you respond inappropriately with these non-verbal cues, the situation could get worse. Training staff to de-escalate these situations can go a long way toward preventing certain violent incidents before they occur.

Unfortunately, part of the WVP program must be responding to active shooter threats. The Federal Bureau of Investigation (FBI) offers “Run-Hide-Fight” training that helps employees know how to respond when an active shooter situation arises. * There are details in the response that must be considered ahead of an incident. If you can run to an area of safety without getting hurt, go quickly, but do not try to coerce co-workers or patients to come with you. In these situations, you must first consider only your own safety if you wish to survive. If you are in a situation where you can hide in a safe place, be sure to turn off your phone and other electronic devices. Incoming calls can make noises which can alert the shooter to your position. If you must fight, use whatever you can find as a weapon, and fight to win. Do not give the shooter any opportunity to fire his weapon.

The laboratory may follow a facility WVP plan or it may create its own, but there should be a safety plan in place for such situations. Be sure to establish a strategy to identify and address the factors that contribute to violence throughout the workplace. Allow for and ensure prompt and accurate reporting of all incidents of violence including those that involve no physical injury. Empower leaders and employees with the necessary tools to eliminate violence in their areas.

The faster workplace violence can be detected, the sooner a good response may occur. However, as with personal wellness planning, prevention is always a solid approach. Avoiding violent situations altogether can be a part of the lab culture with regular education and training. Make sure there is a strong Workplace Violence Plan in action in your laboratory.
