Direct To Consumer Testing: Wave of the Future?

Direct to consumer (DTC) testing is one of the fastest growing industries on the internet, and if laboratories are not careful, we’re going to be blind-sided by it. I wanted to know how this works because in general the websites for this testing have nothing whatsoever on them about the lab. I searched for lab information – accreditation, etc – and found nothing. What I found was that most of these sites are essentially online middlemen between the consumer and the labs – allowing access to lab testing and bypassing the doctor.  I decided to do an experiment and see just how easy it was.

I went online and found a DTC company and ordered tests. I skipped their specials, “test of the month” was a complete thyroid panel, and settled for their most popular, most ordered test. It is actually a group of tests which includes a CBC with differential and a chemistry panel for a total of 27 tests plus six calculated values (eGFR, HDL/total cholesterol ratio, etc). The complete test cost me $97.00 plus tax. I can tell you that those tests run at my institution would cost well over $2500.00, and even at a big reference lab, the best price I could get was about $425.00.

It was when I placed my order that any mention of a lab came into the process. Before I could place the order, I had to make sure there was a LabCorp near me.  I then went back to the website and printed the company’s requisition for the test and took it with me to a LabCorp draw station. They took the requisition, checked it against a photo ID, collected the appropriate blood samples and sent me on my way. Three days later I received an email from the online company that my results were available. I logged on, and it was just that easy.  There were all my test results with appropriate reference intervals and flags. If I want my physician to have a copy, I can have them sent or print them and take them with me.

Amazingly, this is incredibly easy to do, although I suppose you would have to know enough to know what tests to order, or be told what to order by your physician. But I now have the ability to order my own tests, and at significantly less cost than the average hospital or reference lab. If doctors begin telling their patients just what tests to get run and then to bring them the results, this DTC testing will put hospital labs out of business, at least out of the outpatient lab business. There’s no way for a hospital lab to compete with this cost structure. Now all you need is a LabCorp interface to your hospital system and the test results go right back into the chart where the doctor ordered them and the hospital lab is totally outside the loop.

Of course, you will also have people just running tests on themselves after doing some online research, but they will still have to hook up with a doctor somewhere to explain abnormal lab results. I’ve already seen some of that – calls or emails from people off the street looking for explanations of results of metabolic testing. DTC is going to open many, many cans of worms, but it’s coming, nonetheless. I suppose there might be a role for the laboratory professional here, to help the consumer understand their lab results when they do them directly. And hospital labs will always be necessary for STAT and critical tests for inpatients. But the world is changing. We need to be ready for it.
