Reference Interval
These reference intervals are to be used in the interpretation of Borrelia burgdorferi Total Antibodies, IgG and/or IgM by ELISA result
0.99 LIV or lessNegative - Antibody to Borrelia burgdorferi not detected.
1.00-1.20 LIVEquivocal - Repeat testing in 10-14 days may be helpful.
1.21 LIV or greaterPositive - Probable presence of antibody to Borrelia burgdorferi detected.

Interpretive Data
Current CDC recommendations for the serologic diagnosis of Lyme disease are to screen with a polyvalent ELISA test and confirm equivocal and positive results with Western blot. Both IgM and IgG Western blots should be performed on specimens less than four weeks after appearance of erythema migrans. Only IgG Western blot should be performed on specimens greater than four weeks after the disease onset. IgM Western blot 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 Western blot testing within 10 days.

Once this test is performed, if:
a) Negative - no further testing is done;
b) Positive or equivocal - Western blot testing will be performed on the original sample upon receiving a request. Sample will be held for 30 days only.
