Re: Western blot vs igenex
A Western Blot is a type of test and Igenex is the name of a lab. From what I understand Igenex uses 100% pure Lyme antigen when conducting the test, whereas most labs use a lower percentage in order to cut costs. The test determines the amount of free-floating antibodies in the blood. In order to detect them, they must be exposed to antigen. If a more dilute concentration of antigen is used, there is less to react with and fewer antibodies may be detected.
