Hi Rachel Hope and welcome to our forum. First off, testing for lyme disease is very unreliable. I had the Elisa test done by Quest labs and I was negative. There is a blurb on that test that states: The screening test and/or blot for B. burgdorferi antibodies may be falsely negative in early stages of Lyme disease, including the period when erythema migrans is apparent.
I had the Igenex Western Blot and was CDC Negative for both the IgG and IgM. At the bottom of my Igenex lyme test it states: Diagnosis should not be based on laboratory tests alone. Results should be interpreted in conjunction with clinical symptoms and patient history.
I believe in this statement and do not put much credence in the CDC's criteria for a positive. But, just so you know this is how your doctors got their diagnosis.
For IgM WB, the CDC says you are positive if you have 2 of the following bands present, 23-25, 39 and 41.
For IgG WB, the CDC says you are positive if you have 5 of the following bands present, 18, 23-25, 28, 30, 39, 41, 45, 58, 66, 83-93.
I think your first doctor got the IgG mixed up with the IgM.
But, this would not matter to me. The fact that you have bands appearing positive or even IND, I still would rely on the above statement in blue. If you have symptoms
and even 1 positive band or none, I think it is lyme.
Hope this helps.
