ABSTRACT
Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disease characterized by complement-mediated hemolysis.
Objective: Report laboratory tests results related to PNH diagnosis at a reference hospital in the Northeast of México.
Material and method: Retrospective study of results of patients suspected with PNH who underwent four-color cytofluorometry based on detection of CD55, CD59, CD45, CD14 and CD16 at our laboratory from January 2005 to May 2012. An analysis of available demographic variables was performed.
Results: 95 patients—34 (35.7%) males, 53 (55.7%) females and 8 (8.6%) of unknown sex were included in the study. Median age was 38 years; a minimum of a year and up to 87 years. Of the 95 samples, 11 (11.5%) were positive, 82 (86.3%) negative and 2 (2.1%) indeterminate.
Conclusions: A low percentage of positive test results was found even in patients with suspected diagnosis of PNH. The four-color cyto-fluorometry is a useful diagnostic tool for this disease.
