Hemoglobin consists of an iron-containing heme ring and four globin chains: two alpha and two nonalpha. A new technique for differentiation of hemoglobin. HPCL, also called High-performance chromatography test, is used to screen thalassemia and other blood diseases. Beta thalassemia is the result of deficient or absent synthesis of beta globin chains, leading to excess alpha chains. Reference Interval: Refer to laboratory.

Bone marrow transplantation in childhood is the only curative therapy for beta thalassemia major. Cellulose acetate (CA) electrophoresis at pH 8.2-8.6 can be used to resolve common variants such as HbS and HbC, but it cannot be used to distinguish between HbS and HbDPunjab and HbGPhiladelphia.

The electrophoresis results will then show the types of hemoglobin present and the levels of each type. Hoffman: Hematology: Basic Principles and Practice. Alpha thalassemia is caused by reduced or absent synthesis of alpha globin chains, and beta thalassemia is caused by reduced or absent synthesis of beta globin chains. Your doctor may recommend a hemoglobin electrophoresis test to determine if you have a disorder that causes the production of abnormal hemoglobin. The problem can be so severe that it can even interrupt the regular progression of the gestation, causing side effects such as: As your hemoglobin levels keep falling, the symptoms will get worse and worse. 1000 to Rs. To rule out any blood disorders like thalassemia, sickle cell anemia etc. Hemoglobin electrophoresis is used as a screening test to identify normal and abnormal hemoglobins and assess their quantity. In HbSS, the full blood count reveals hemoglobin levels in the range of 6-8 g/dL with a high reticulocyte count (as the bone marrow compensates for the destruction of sickle cells by producing more red blood cells). If you had a hemoglobin electrophoresis test because you had certain symptoms, you should call your healthcare provider to review your results. Therefore, although a microcytic anemia with a normal RDW will almost always be because of thalassemia, persons with an elevated RDW will require additional testing (Figure 2).9.
