This test is performed using flow cytometry and is a single-tube, whole-blood assay incorporating CD45, CD19, and CD20 antibodies. After staining with specific antibodies, the red blood cells are lysed and the sample is analyzed by flow cytometry on a BD FACS Canto flow cytometer. Absolute counts are obtained using BD Trucount (BD BioSciences) tubes. Both percent and absolute count will be reported for CD19 and CD20+ B cells. An absolute count will be reported for CD45.(Unpublished Mayo method)
