Miniature chromatography of haemoglobin A2 and heterozygous beta thalassemia.
172 beta thalassemias are detected by applying a new method of haemoglobin A2 determination: Miniature chromotography on DEAE cellulose. This procedure is simple, fast, accurate and there is no significant difference with macro-chromatography. It is proposed as standard method for determination of hemolgobin A2. This study was made on 400 patients suspected of beta thalassemia, the majority of which presented with a considerable microcythemia.
