Abstract

Detection of hemoglobin (Hb) variants represents an important issue for diagnosis and adequate treatment of hemoglobinopathies. The Capillarys 2 Flex Piercing analyzer (Capillarys) by Sebia is routinely used in our clinical laboratories to detect Hb variants in peripheral blood (PB). This automated method separates Hb fractions by capillary electrophoresis, giving a spectrophotometric measure of their relative proportion. The scientific research in the field of hemoglobinopathies needs robust procedures to evaluate the efficacy of experimental therapies, as gene therapy. We investigated for the first time the feasibility to use Capillarys on cellular lysates from in vitro erythroid cultures. Because total Hb concentration in erythroid lysates is up to 20-fold lower than in hemolysates from PB, we analyzed diluted blood samples, thanks to the manual mode included in the Capillarys setting. We compared analytical precision, accuracy, sensitivity, and specificity of this procedure to the automatic method, routinely used in diagnostics. For instance, adult Hb intra- and interassay precision were estimated as coefficient of variation 0.2% and 0.3%, respectively. The manual mode is less robust for detection of fractions
