Beta-thalassaemia trait in Mosul

A prospective study was conducted in order to determine diagnostic parameters for Beta-thalassaemia trait in Mosul. Both elevated Hb-A2 and resistance to lysis using one tube osmotic fragility test at 0.36% NaCl concentration were found to discriminate accurately between the control and the obligatory Beta-thalassaemia carrier groups. Also more than three quarters of our patients were found to have an elevated Hb F level above 1% with a range of 1.7 to 3.3%. Our results compared favourably with other studies
