#ExistRefRange>0.99 LIV or less: Negative - Antibody to Borrelia burgdorferi not detected.
1.00-1.20 LIV: Equivocal - Repeat testing in 10-14 days may be helpful.
1.21 LIV or greater: Positive - Probable presence of antibody to Borrelia burgdorferi detected.
#ExistInterpData>The detection of antibodies to Borrelia burgdorferi in cerebrospinal fluid may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier.
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 samples less than four weeks after appearance of erythema migrans. Only IgG Western blot should be performed on samples 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.

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.
