For children, the Mentzer index (MCV/red blood cell count) can help distinguish between iron deficiency and thalassemia. There are usually two genes, but if there is only one gene for HgS and the other is HgA then the person is a carrier, but if there are two of the HgC or HgS genes or one is HgS and the other is HgC then the person has the actual condition. Microcytic hypochromic red cells with normal or borderline low Hb Diagnosed on HPLC or Hb electrophoresis - HbA2 > 3.5%, often elevated Hb F Red cell distribution width (RDW) is often normal Pre-pregnancy carrier testing of partner is important (Ensure parents have been tested if likely to have more children) [3], Automated high-pressure liquid chromatography instruments are proving to be useful alternative methods for hemoglobinopathy screening.
