HbA1c analysis by capillary electrophoresis - comparison with chromatography and an immunological method.

Background: Haemoglobin A1c (HbA1c) has become an even more important analyte for clinical laboratories during recent years with the introduction of its diagnostic use for diabetes mellitus. Several different analytical principles can be used, each with their advantages and disadvantages.

Aim: We wanted to compare Sebia Capillarys 2 Flex Piercing (Capillarys) with our routine HbA1c methods, which were an HPLC method (Tosoh G7) and an immunoassay (Tina-Quant on Roche Modular P) by analysing a large clinical material.

[Hemoglobinopathies and patients with foreign names].

Background: The diagnosis of haemoglobinopathies is of growing importance in Norway because of increasing immigration from countries where haemoglobinopathies are prevalent conditions. The aim of this study was to investigate the relationship between mean corpuscular volume (MCV) and the various haemoglobinopathies diagnosed in Norway.

Material And Methods: For a period of three years, all samples with MCV lower than 70 fl were also examined for beta-thalassaemia and haemoglobin variants HbS, HbC, HbE and HbD.
