Background: β-Thalassaemia syndromes are inherited group of abnormalities of hemoglobin synthesis. These abnormalities characterized by a defect in β-globin genes which may result either in the reduction or absence of one or more of the β-globin chains of hemoglobin. This genetic defect can be homozygous or heterozygous.
Aim of this study was to detect the hematological parameters of β-thalassaemia trait in premarital screening individuals in Nineveh province.
Subjects and Methods: This is a cross sectional study that was performed in Nineveh province in three main centers for premarital screening program. In the period between the 15 November 2019 and the 15 May 2020 a total of 1127 subjects who attend to these centers were screened for carrier conditions of β-thalassemia. Blood samples of the couples were obtained during attendance to the marriage office. Complete blood counts and hemoglobin variant analysis were performed with automated counter and high performance liquid chromatography technique.
Results : Out of 1127, β-thalassaemia trait was diagnosed in 47 subjects, 31 were male (66 %) and 16 were female (34 %). The mean of their hemoglobins was 14.4 g/dl in males, and 12.5 g/dl in females. The mean of mean cell volume and mean cell hemoglobin were 68.3fl and 22.4pg respectively. The mean for HbA2 concentration was 4.9 % and for HbF was 1.2%.
Conclusion: β-thalassaemia trait is usually presented with low MCV and/or low MCH but the accurate and dependable technique in detecting carriers is the use of High Performance Liquid Chromatography (HPLC).
