I have read on a few posts here about the CD57 test and as a newbie I have no idea what that test is. Is it a blood test and what are you measuring with the test? Thanks-D

This test is a blood test that measures the amount of a certain type of white blood cell (part of your immune system) that is believed by some MD's to indicate status of Lyme infection (lower number = more active infection).

Specific tech-talk: CD57 is one type of Natural Killer Cell, which is a type of Lymphocyte, that is not commonly measured -- most MD's don't know it exists or don't think it is indicative of anything significant if it is abnormal.

I hope this helps - take care,

Thanks alot Razzle! My natural killer cells done on a T&B cell test are actually elevated. Does this sound like Lyme to you? D
