Hemoglobin A2 Control, Normal & Elevated
The measurement of hemoglobin A2 is important in the diagnosis of thalessemia. The most commonly used diagnostic procedures are alkaline cellulose electrophoresis and column chromatography. BGT’s normal and elevated A2 controls are specifically prepared to be useful in both procedures. The total hemoglobin is adjusted to about 4.0 gm/dl and the normal control contains from 1.5%-2.5% A2, while the elevated contains 3.5% to 5.0%. The reconstituted controls can be applied directly in either procedure without further dilution. For procedures which measure A2 in the presence of hemoglobin S, please inquire. The bulk product may also be order OEM to dispense and lyophilized on location (minimum 1 liter).
