The usual test that is done for Lyme is not conclusive (including the Western Blot). It is very much a clinical diagnosis according to the International Lyme and Associated Diseases Society and the CDC. Some Labs that are Lyme specific are Igenex and Bowen and MDL. I am going through the Lyme confusion and am trying to find the truth about whether or not I have Lyme. I see I need to go to a Lyme specialist. The usual doctor doesn't know enough about it. There are many good Lyme websites for good information. Some have doctor referrals. I called Igenex Lab in Palo Alto, CA and they referred me to a doctor in my area whom I will see soon. Hope this might help.
