Serum, plasma, or synovial fluid samples are tested quantitatively for IgM, IgG and IgA to B. burgdorferi using antibody capture enzyme immunoassays (EIA). In addition, two immunoblots for IgG antibody will be performed using two strains of B. burgdorferi which differ in their outer surface protein expression, to eliminate problems due to vaccination with recombinant OspA Lyme vaccine. Results of immunoblotting will include images of the reaction strips (when interpreted as positive) and a listing of the polypeptides reactive with patient antibody. If the acute specimen is negative (i.e. antibodies undetectable) and the clinical history strongly suggests infection, collect a convalescent specimen 3-4 weeks later.

Follow-up Lyme Antibody Analysis

Retest of original sample in parallel with a new sample (i.e. acute and convalescent) will be performed as described above.
