Reference Interval:

Negative, <0.9 AI

Interpretative Data:

  •  <0.90 AI, negative,  Absence of detectable Borrelia burgdorferi antibodies. A negative result does not exclude the possibility of Borrelia burgdorferi infection. If early Lyme disease is suspected, a second sample should be collected and tested two to four weeks later.
  • >/=0.90 AI and <1.10, equivocal, The imprecision inherent in this method does not allow definitive categorization of samples that read close to the cutoff. All equivocal samples will be tested further following the Standard Two-Tier Testing (STTT).
  • >/= 1.10, positive, Presence of detectable Borrelia burgdorferi antibodies. All positive results will be tested further following the Standard Two-Tier Testing (STTT).
