Hemoglobin Alpha Genotype Finding

**Semantic type:** Laboratory or Test Result

**Definition:** A genetic finding indicating the genotype in a subject for the genes that encode hemoglobin subunit alpha, HBA1 and HBA2. Since the two HBA genes encode the same protein and are co-located on chromosome 16, the normal genotype is comprised of 2 maternal alpha genes and 2 paternal alpha genes (aa/aa).
