Labcorp hemoglobin electrophoresis.
Alpha thalassemia occurs when one or more of the 4 alpha-globin genes that make up part of the hemoglobin molecule are missing or damaged. Alpha thalassemia silent carrier. One gene is missing or damaged, and the other 3 are normal. Blood tests are often normal. Your red blood cells may be smaller than normal.

The hemoglobin electrophoresis test is designed to detect genetic abnormalities in the structure of a person's hemoglobin. Hemoglobin electrophoresis is typically done when a person has signs or symptoms of hemolytic anemia, a family history of a hemoglobinopathy, an abnormal complete blood count (CBC) test, or a positive neonatal screening test.Test: Hemoglobin Electrophoresis. Hemoglobin electrophoresis is probably the most useful laboratory method for separating and measuring normal and some abnormal Hb. Through electrophoresis, different types of Hb are separated to form a series of distinctly pigmented bands in a medium (cellulose acetate or starch gel).This includes especially common variants that produce hemoglobin (Hb) C, D, E, and others. An approach to Hb C genetic test results is presented separately. (See "Gene test interpretation: Hemoglobin C (Hb C) variant in the hemoglobin beta locus ( HBB )" .) Separate topic reviews discuss the sickle cell variant that causes sickle cell …

In children with normocytic hemolytic anemia, if results of electrophoresis show only HbS with an HbF concentration of less than 30%, the diagnosis is sickle cell anemia.Hemoglobin Electrophoresis (Isoelectric Focusing) Description. Hemoglobin electrophoresis alone is not adequate for diagnosing thalassemia. Electrophoresis is limited to identification without fractionation, quantification or interpretation. This test is useful for screening for sickle cell trait for athletes other than those on UW teams.The thalassemias are a group of hemoglobinopathies in which the normal ratio of alpha globin to beta globin production is disrupted due to a genetic variant in one or more alpha or beta globin genes. This abnormal alpha chain to beta chain ratio causes the unpaired chains to precipitate, leading to destruction of red blood cell (RBC) precursors ...Laboratory Services. Hemoglobin HPLC.
