Analysis of hematological characteristics of patient with different genotypes in lightβ-thalassemia / 实用医学杂志

ABSTRACT

Objective To investigate the hematological characteristics of patients with light β- thalassae-mia and rapidly identify different mutational genotypes. Methods RBC、Hb、MCV、MCH、MCHC、RDW-CV and HbA2 were studied in the 646 patients,the differences between β0/βN and β +/βN mutations were also compared. Results Most of them were microcytic hypochromic anemia. The most common genotype were β654/βN(33%)、β41-42/βN(32.5%)、β17/βN(14.4%)、β - 28/βN(10%)respectively,β0/βN were relatively higher. The differences in RBC、MCV、MCH、RDW-CV and HbA2 were significant between β0/βN and β +/βN. Compared with β +/βN patients,the MCV and MCH of β0/βN were significantly reduced,RDW-CV and HbA2 were significantly higher. Conclusion Light β- thalassaemia with different genotypes has its own unique hematological features and can be quickly and ef-fectively identified. Clinical efficiency can be improved through hematological analysis.
