Research presented today at the National Kidney Foundation spring clinical meeting indicates that manual microscopy surpasses automated analyzers when assessing kidney injury. The abstract is titled “Manual Microscopy: Not a Lost Art” and says, in part: “In this study, we examined if a significant difference exists between the reported ranges of granular and muddy brown casts using manual microscopy as compared to an automated urine analyzer in an acute kidney injury cohort.”
According to one of the abstract’s authors, Dr. Sharda, “What our research has been able to show so far is that the automated system under reported the value of granular casts in our patient cohort of acute kidney injury. The automated system still has utility as a screening test, but manual microscopy should be done in all cases of abnormal kidney function, as accurate quantification of casts could have some prognostic benefit to patients.”
The poster is available online. The authors are currently writing a paper on their research; their contact information is here.

Theoretical knowledge helps troubleshoot wonky results, but unfortunately that knowledge is easy to forget if it’s not used every day. If you’ve worked the chemistry bench long enough to have forgotten some of theory behind the analytes, check out this series of articles to refresh your memory.

As may or may not be aware, Lab Medicine has a podcast series geared toward laboratory professionals and pathologists. In a recent installment, Dr. Geoffrey Wool discusses the laboratory’s role in monitoring the new anticoagulants. Click this link to listen.
The common maxim when buying laboratory equipment is “Fast, accurate, or cheap; pick two.” The perfect analyzer would have all three qualities, but as the saying suggests, it’s hard to find those instruments. Enter Beckman Coulter. Their website suggests the UniCel DxH800 is designed to meet these demands by improving productivity, decreasing turnaround time and reducing overall cost.
Recently Lab Medicine published a paper evaluating the performance of Beckman Coulter’s Unicel DxH800. The authors of the paper found the instrument to be accurate and efficient. They also commented that for larger facilities, this analyzer could improve productivity and turnaround times when compared to the older model (LH 750). Notably, the authors don’t mention cost, quality control, or maintenance concerns.
Does your laboratory have the DxH800? Is the maintenance easy to perform? Has this analyzer improved turnaround times in your lab? Let us know in the comments.
