Hemoglobin(HB) Electrophoresis
The Haemoglobin (Hb) Electrophoresis Test is a specialized blood test used to separate and identify different types of haemoglobin present in the blood. This is achieved through an electrophoresis technique that classifies haemoglobin based on its electrical properties.
The test is commonly used to diagnose haemoglobin disorders such as thalassemia, sickle cell disease, and other abnormal haemoglobin variants.
The purpose of this test is to:
- Identify and differentiate types of haemoglobin
- Diagnose haemoglobin disorders such as thalassemia and sickle cell disease
- Detect abnormal haemoglobin variants
- Evaluate unexplained anemia
- Support genetic counseling and screening
HEMOGLOBIN(HB) ELECTROPHORESIS Test
The Haemoglobin (Hb) Electrophoresis test separates and identifies different types of haemoglobin present in the blood. It is mainly used to detect abnormal haemoglobin variants and inherited haemoglobin disorders.
The test can help in the evaluation of conditions such as sickle cell disease, sickle cell trait, thalassemia, and other hemoglobinopathies. It may also be recommended when a person has unexplained anemia, abnormal red blood cell indices, or a family history of inherited blood disorders.
Haemoglobin electrophoresis is often interpreted along with a CBC, peripheral smear, iron studies, and other laboratory findings to provide a more complete assessment.
Test Recommended for Individuals:
- Individuals with unexplained or persistent anemia
- People with abnormal CBC or red blood cell indices
- Individuals suspected of having thalassemia or sickle cell disorders
- People with a family history of haemoglobin disorders
- Couples undergoing pre-marital or pre-pregnancy screening
- Pregnant women when hemoglobinopathy screening is advised
- Individuals with a suspected abnormal haemoglobin variant
- Patients advised by their healthcare provider to undergo haemoglobin analysis
FAQs
1. What does the Haemoglobin (Hb) Electrophoresis test detect?
It identifies different types of haemoglobin and helps detect abnormal variants associated with conditions such as thalassemia, sickle cell disease, and sickle cell trait.
2. Why is Haemoglobin Electrophoresis done for anemia?
Some inherited haemoglobin disorders can cause anemia or changes in red blood cell size. The test helps determine whether an underlying hemoglobinopathy could be contributing to abnormal blood results.
3. Can Haemoglobin Electrophoresis detect thalassemia trait?
It can identify patterns suggestive of certain types of thalassemia, particularly beta-thalassemia trait. However, some forms, such as alpha-thalassemia, may require additional testing, including genetic testing, for confirmation.
