Lyme Disease Antibodies
Negative Less than 0.90
Equivocal 0.90-1.09
Positive Greater than 1.10
Limitations:Patients may be serologically negative during the early stages of the disease. Potential assay interference due to circulating antibodies in patients with Human Ehrlichiosis (HGE) and Tick-Borne Relapsing Fever (TBRF), Babesiosis, Parvovirus, and EBV infections have been found. Interpret results from these patients with caution.
Use:Diagnosis of Lyme disease in conjunction with clinical manifestations. Borrelia burgdorferi IgM and IgG antibodies are usually present within 1-3 weeks after disease onset.
