HBA2 and thalassemia: The proband presented thalassaemia-like hematological features, reduced mean corpuscular volume (MCV 65.6 fl), mean corpuscular haemoglobin (MCH 21.5 pg), increased HbA2 (3.8%), reticulocytes 2.6 (×1000), but haemoglobin concentration (14,8 g/dl) was higher as compared to beta thalassemia carriers.
