I had a Lyme test run recently, and it came back negative. It was sent to the Mayo Clinic, and they checked for Lyme IgG Western Blot and Lyme IgM Western Blot. I did ask my doctor at the time about Igenex labs, but I was told we can't really use them because of insurance. If I were to pursue this and press for Igenex ... well, it's just REALLY expensive. Are the tests run at Mayo really unreliable??
