LYME EIA Antibody testing can be falsely negative, if serum collection is early in the disease, or after treatment.  Additional serial testing may be needed when a false negative is suspected.  The test may be falsely positive due to auto-antibodies, cross reacting organisms, or other foreign antigens.

Current CDC recommendations suggest that all Lyme antibody EIA screening results that are Positive or Equivocal should be sent for Western Blot testing.  All specimens reported with Positive or Equivocal results will be frozen for 30 days should additional testing be needed.
