One major peak with hba
WebHemoglobin A2 ( HbA2) is a normal variant of hemoglobin A that consists of two alpha and two delta chains (α 2 δ 2) and is found at low levels in normal human blood. Hemoglobin A2 may be increased in beta thalassemia or in people who are heterozygous for the beta thalassemia gene. HbA2 exists in small amounts in all adult humans (1.5–3.1% ... WebElevated HbA2, as seen in the parents of the child, occurs in beta-thalassemia due to decreased production of beta globin. This causes a molar excess of free alpha globin subunits available to bind delta globin. The net result is …
