Anyone? I can't seem to find this anywhere. I asked for the paperwork to be mailed to me but my doc is out until Monday... LabCorp won't even tell me the reference range over the phone. Jerks.
If you have a Labcorp results report you should probably have the two following lines from a CD57 test:
%CD8-/CD57+ Lymphs -% 2-17 (normal range)
Abs.CD8-CD57+ Lymphs -/uL 60-360 (normal range)
The "-" is what your specific numbers are. The bottom number (the Abs (Absolute) number) is generally what is tracked. Under 60 is low. The % number you mention 5% is in the normal range but the other number is often whats referred to in Lyme testing.
Many LLMDs no longer place a significant emphasis on CD-57 - the correlation has still not been firmly established.
Hope this helps.
