Values of mean cell volume and mean sphered cell volume can differentiate hereditary spherocytosis and thalassemia
2014
AbstractObjectivesTo determine whether the values of mean cell volume (MCV) and mean sphered cell volume (MSCV) can distinguish hereditary spherocytosis (HS) from thalassemia.MethodsThe MCV, MSCV, and other erythrocyte indexes were measured in totally 263 people, 57 HS patients, 109 thalassemia patients, and 107 normal control subjects. All indexes were derived from measurements obtained by the Beckman–Coulter LH 750 Hematology Analyzer.ResultsThe MSCV was significantly lower in the HS group compared with the thalassemia group (P < 0.001), but the MCV was significantly higher in the HS group compared with the thalassemia group (P < 0.001). Among 57 patients with HS, the MCV was higher than the MSCV in 56 patients. The MCV was lower than the MSCV in one patient combined with β-thalassemia. In the control and thalassemia groups, the MCV was lower than the MSCV.ConclusionMeasurements of the MCV higher than the MSCV can be considered an ideal index to distinguish rapidly HS from thalassemia.
