CD57 is 30 - what does it mean?

Hi everyone,

My Western Blot for Lyme was negative. (Infectolab, Germany)
My LTT for Lyme was negative - 1 IU. (Infectolab)
My LTT for Yersinia was weak positive. (Infectolab)
My CD57 was low - 30 ("normal" range is 60-360). (Local AUS lab)
I have many symptoms of Lyme Disease, Chlamydia Pneumonia and Mycoplasma.

My doctor said a low CD57 can be associated with:
•Chronic Lyme Disease
•Chlamydia
•Tuberculosis
•HIV/AIDS

I was confirmed immune to tuberculosis by a blood test last year (after another immunisation injection).

I've never had a blood transfusion or been sexually active.

I've been ill for over 3 years now. It began with the most terrible flu-like sickness. I was later diagnosed with fibromyalgia, chronic fatigue syndrome, Celiac disease and more...

Any thoughts on the likelihood of Lyme?
What else could a low CD57 mean?
Does it sometimes bear no significance to health status?
IS it actually a reliable indicator of Lyme?

I think it's a measure of your immune system and how much of a certain type of killer cell you have. 125+ is usually the level of someone with a healthy immune system. Less than 60 can be a sign of chronic lyme. I think it's a measure that's pretty much used for lyme disease. But everyone's immune system is so different it's probably best for your doc to interpret the results.

An elevated c4a is more specific to chronic lyme.
