Haemoglobin A2 measurement using high performance liquid chromatography. 1992

R Deacon-Smith, and I Lord

Department of Haematology, Poole General Hospital, England, UK.

Haemoglobin A2 levels were assessed using a modular high performance liquid chromatography (HPLC) system with a protocol designed for the measurement of haemoglobin A1C. There was good correlation (r = 0.96; P < 0.001) between this technique and the International Committee for Standardisation in Haematology (ICSH) recommended method of microchromatography. The range of haemoglobin A2 was found to be 2.3-3.2% in apparently normal individuals, and 4.0-6.7% in those with beta-thalassaemia trait. The HPLC system produced reliable results quickly for haemoglobin A2 with no alteration to the protocol used for measuring haemoglobin A1C.

D006443	Hemoglobin A2	An adult hemoglobin component normally present in hemolysates from human erythrocytes in concentrations of about 3%. The hemoglobin is composed of two alpha chains and two delta chains. The percentage of HbA2 varies in some hematologic disorders, but is about double in beta-thalassemia.	A2, Hemoglobin

D017086	beta-Thalassemia	A disorder characterized by reduced synthesis of the beta chains of hemoglobin. There is retardation of hemoglobin A synthesis in the heterozygous form (thalassemia minor), which is asymptomatic, while in the homozygous form (thalassemia major, Cooley's anemia, Mediterranean anemia, erythroblastic anemia), which can result in severe complications and even death, hemoglobin A synthesis is absent.
