I've searched this board and googled the web and can't find the answer to this question. Why is the CD57 test "time-sensitive"? I've seen many posts stating that it is and to never draw the blood on a Friday but why exactly is it time-sensitive? Does it make the Abs.CD8-CD57+ Lymphs number come out lower?
Thanks for all input.

jason,
i believe what it means is that the blood sample shouldnt lay around for days after being drawn but should be processed as quickly as possible since it could alter the results.
however, i am not sure in which way. Labcorp is the lab that invented the test. you could contact your nearest one and ask this specific question.

That's a good idea. I'll do that tomorrow. The last test we ran my wife's CD57 dropped from 98 to 38 in 2 months yet she is feeling slightly better. I'm trying to figure out what the heck is going on. After researching a bit I found the 12 hour thing then noticed that on her last test the blood draw was on a Friday at a local LabCorp facility. They didn't express any concerns for drawing blood on a Friday for a CD57 test.

I wouldn't rely on LabCorp's staff for anything. They fall far short of competent many times.

It's my understanding that it doesn't exactly correspond to treatment response.
It will supposedly fluctuate but stay in the low range while the infection is not yet controlled and then make a big jump to a more normal range.

Actually Seek- I think that the CD-57 is the ONE test Labcorp is actually recommended for, but I believe "Stricker Panel" needs to be stated on the Rx or they may mess not know what you're looking for.
