Hemoglobin ELISA kits are assays designed to detect the iron-containing protein hemoglobin. It facilitates oxygen exchange within red blood cells in the bloodstream. It features a quaternary globular protein with a porphyrin ring. The most common type of hemoglobin in adult humans is hemoglobin A, which consists of two α and two β subunits. In infants, it consists of two α and two γ subunits. Low levels of hemoglobin could be an indication of anemia.
