Refer to report.
This panel is appropriate for Lyme disease testing greater than 4 weeks from erythema migrans or onset of disease symptoms.
A negative result indicates that the immunoblot evaluation for B. burgdorferi antibody demonstrates no antibodies unique to B. burgdorferi and is, therefore, not supportive of Lyme disease.
A positive result indicates that the immunoblot evaluation for B. burgdorferi antibody is consistent with the presence of antibody produced by patients in response to infection by B. burgdorferi and suggests the presence of Lyme disease. Although the test has been shown to have a high degree of reliability for diagnostic purposes, laboratory data should always be correlated with clinical findings.
Current CDC recommendations for the serological diagnosis of Lyme disease are to screen with a polyvalent EIA test and confirm equivocal and positive with immunoblot. Both IgM and IgG immunoblots should be performed on specimens obtained less than 4 weeks after appearance of erythema migrans. Only IgG immunoblot is to be performed on specimens greater than 4 weeks after disease onset. IgM Immunoblot in the chronic stage is not recommended and does not aid in the diagnosis of neuroborreliosis or chronic Lyme disease. Please submit requests for appropriate immunoblot testing within 10 days.
If ELISA result is 1.00 LIV or greater, then IgG immunoblot will be added. Additional charges apply.
