The assay is performed by indirect fluorescent antibody (IFA) method. Titer values above the reference intervals are considered evidence of current infection or past infection (e.g. within the last year). uspected chronic infection. The assay is performed by indirect fluorescent antibody (IFA) methods. Titer values above the reference intervals are considered evidence of current infection or past infection (e.g. within the last year).

Procedure

Human IgG antibody to Babesia duncani (B. duncani) WA1 antigens are detected by an indirect fluorescent antibody (IFA) assay. Briefly, a slide coated with fixed, B. duncani infected red blood cells are incubated with the diluted human serum sample. If specific B. duncani antibodies are present, they remain bound, are then labeled by a fluorescein-labeled antibody conjugate, and then detected by fluorescence microscopy. This test was developed and its performance characteristics were determined by Viracor Eurofins.This test has not been cleared or approved by the U.S. Food and Drug Administration. Results should be used in conjunction with clinical findings, and should not form the sole basis for a diagnosis or treatment decision.

Specificity

Sera from patients shown to have been infected by the tick-borne pathogens--Babesia microti, Rickettsia rickettsii and Borrelia burgdorferi--were tested and found to be negative by the B. duncani WA1 IgG IFA assay.
