Hb Electrophoresis Test
The Hb Electrophoresis test measures the different types of hemoglobin in the blood and helps diagnose various conditions related to abnormal hemoglobin production, such as anemia, sickle cell disease, and other hemoglobin disorders.
Test Description
Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Hemoglobin electrophoresis separates the different types of hemoglobin in the blood, allowing healthcare providers to evaluate their levels. There are several types of hemoglobin, including:
- Hemoglobin (Hgb) A, the most common type in healthy adults
- Hemoglobin (Hgb) F, fetal hemoglobin
- Hemoglobin (Hgb) S, sickle cell hemoglobin
- Hemoglobin (Hgb) C, an abnormal form associated with excessive red blood cell destruction
- Hemoglobin (Hgb) H, an abnormal form associated with thalassemia.
Indications of the Test
The test is often used to diagnose conditions related to abnormal hemoglobin production, such as fatigue, pale skin, jaundice, symptoms of a blood disorder, high risk for a blood disorder due to race, a child with a blood disorder, and an abnormal result from another blood test.
Patient Preparation/Instructions
There is no special preparation required for the test. However, patients should inform their doctor if they have had a blood transfusion in the past 12 weeks, as this could affect the test results.
Typical Reference Values
Normal levels of different hemoglobin types vary among individuals. For example, in adults, normal percentages of different hemoglobin molecules include:
- Hgb A: 90-95%
- Hgb A2: 15-25%
- Hgb F: 0-2% (in adults)
Turn Around Time
The test typically takes about an hour to process, but it may take a few days for the healthcare provider to receive and evaluate the results.
