[Determination of hemoglobin A2 (HbA2) by ion exchange resins freely suspended in test tubes].
Two methods to measure HbA2 are compared in order to discriminate the beta-thalassemia minor. Both the methods are based on the property of DEAE microgranular cellulose to bind every physiological haemoglobins but not the HbA2. However one method is based on conventional microchromatographic use of the resin while the second one the resin is in a test tube. The last application is very easily applied in the routine analysis for its rapidity without decreasing precision and accuracy.
