Screening assay for Babesia microti infection or exposure
The diagnosis of acute babesiosis cannot be confirmed solely by the presence of Babesia antibody in a serum sample collected at a single time point. Antibody detection by serologic testing can provide supportive evidence for the diagnosis of babesiosis but does not reliably distinguish between active and prior infection.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Immediately following collection, mix sample by gently inverting 5 times
