  • Title: [Determination of HbA2 by a microchromatographic method. Reliability and simplification of the use of prepared columns].

    Journal: Pediatr Med Chir; 1988; 10(2):213-6. PubMed ID: 3174484.
    Abstract:
    A modified procedure for hemoglobin A2 determination by microchromatography was developed simplifying an easily commercially available column kit method. Blood samples were analyzed simultaneously by means of DE-52 microchromatography described by Huisman et al. (reference 12) to check the reliability of the new modified method. In the Pediatric Clinic of Cagliari University where the original Huisman method was used the values of HbA2 obtained were as follows: Normal subjects (35 cases) 2.470 +/- 0.351, beta-Thalassemia heterozygous subjects (38 cases) 5.142 +/- 0.342. The modified method gave respectively the following results: Normal subjects 2.578 +/- 0.303, beta-Thalassemia heterozygous subjects 5.465 +/- 0.400. No overlap was found between normal and beta-thalassemia trait samples. It is suggested that the simplified method is very reliable and very simple to organize even in laboratories with few facilities and when needs for only few tests per week exist.
