Method Description

The patient’s serum is diluted and is placed in microscopic slide wells, which have been coated with Babesia microti-infected red blood cells from Syrian hamsters. After incubation, the slides are washed and a fluorescein-isothiocyanate conjugate is added to each well. The slides are then read using a fluorescence microscope and significant fluorescent staining of intraerythrocytic organisms constitutes a positive reaction.(Krause PJ, Telford III SR, Ryan R, et al.
