title: Quantitation of Hb a2 with DE-52 microchromatography in whole blood as screening test for beta-thalassemia heterozygotes.
abstract: HB A2 was assayed by means of DE-52 microchromatography in hemolysates from 285 normal subjects and 223 beta-thalassemia heterozygotes. No overlap was found between both groups. Comparable results were observed analyzing whole blood samples collected in capillary tubes from 550 normal subjects and 295 beta-thalassemia heterozygotes. Our results demonstrate that this technique is useful in a screening program for beta-thalassemia trait.
