Wow - years ago positive and you only did 2 weeks of doxy? I am so very sorry. You should have had much more than that.
Different labs can be one explanation.
Hiding spirochetes can be another.
You are not producing any antibodies to show up on the test.
I think all of those, or just one can be the reasoning.
Diagnosis is based on symptoms, not test results because tests results can be falsely negative.
