| Additional information | Flow cytometric immunophenotyping is used to study the leukocyte and RBC surface markers of glycosylphosphatidylinositol (GPI) linked antigens such as CD14 (monocytes) and CD59 (neutrophils and RBC). Fluorescent aerolysin (FLAER), a protein that selectively binds to GPI anchors, is also used in the test. Patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) will show abnormality in all or some of these markers to various extents | ||
