Persons with beta thalassemia major are almost never symptomatic at birth because of the presence of HbF, but symptoms begin to develop by six months of age. A too low value of hemoglobin A2 - associated with low MCV and low MCH - with normal values of iron and ferritin, should lead to suspect a variant of hemoglobin. To rule out any blood disorders like thalassemia, sickle cell anemia etc. Beta thalassemia intermedia is less severe than beta thalassemia major and may require episodic blood transfusions. The hemoglobins move on the paper and form bands that show the amount of each type of hemoglobin. Background Hemoglobin (Hb) measurement is a standard test among pregnant women during the first perinatal visit that is used to evaluate physical status and anemia. Haemoglobin electrophoresis analyses the various kinds of the oxygen-carrying protein (Haemoglobin) in the blood. IEF and electrophoresis both use electric currents to separate hemoglobin types. The normal range is just a guide. In other forms of sickle-cell disease, Hb levels tend to be higher. This test is done to diagnose blood disorders, as a screening test for genetic conditions, and monitor treatment efficacy in patients having blood disorders.

Hemoglobin C trait is inherited from one's parents, like hair color or eye color. It also looks for abnormal types of hemoglobin. How much does a hemoglobin electrophoresis test cost? Too high or too low hemoglobin levels they can therefore mean: The results can also show whether a specific disorder is mild, moderate, or severe. 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. Hemoglobin types react to the electric current, moving away from each other. The red cell count and indices are indistinguishable from beta thalassemia trait, but the Hb A 2 level is normal. Most patients with abnormal hemoglobins have no symptoms but could potentially transmit the gene to their fetus. Last medically reviewed on March 29, 2017, Normal hemoglobin levels can vary based on several factors, including age and sex. It has 2 variants.
