Normal range: Negative
Comment: Detects the paroxysmal nocturnal hemoglobinuria (PNH) abnormality. PNH has been a candidate for myeloproliferative disease occurring in 55-65% of cases of myeloid metaplasia and primary myelofibrosis. Hemosiderin in urine should also be measured. CD55:CD59 ratio is a better test for diagnosing this disease
Sample: EDTA whole blood
