HbF + HbA2 Single Level Control (Lyophilized)
For Detection of β- and δβ-Thalassemia
Normal adult blood contains mainly HbA, less than 0.8% HbF, and a small percentage ( less than 3.3%) of HbA2α2δ2. The estimation of the relative amount of HbF is a very important aspect in the diagnosis of homozygous β-thalassemia in all its forms. It is also necessary for the diagnosis of the heterozygous states for β-thalassemia and the different varieties of hereditary persistence of fetal hemoglobin (HPFH). The level of HbF in β-thalassemia minor is usually normal, but some 30% of cases have elevated levels usually up to 1.5%, and occasionally above 3%.
The extendSURE™ single level HbF/A2 control kitset is available for electrophoresis and the Alkali Denaturation method. The kit contains 6 vials (1mL). These have an unopened shelf life of 3 years when stored at 2° - 8°C with open vial stability of 2 weeks after reconstitution when stored at 2° - 8°C.
