Hi Everyone, I just got my CD57 results back and it is 76. My dr. was telling me about how they came up with the ranges (since >60 is considered normal). He said that according to a conference that he attended they now consider above 100 to be normal. I can't find this reference anywhere. Just wondering what everyone elses drs are saying. P.S. I have been taking Cat's Claw for about 8 months and that is suppose to raise your CD57.
