Haemoglobin Variant HPLC (HB HPLC)

The Haemoglobin Variant HPLC (High-Performance Liquid Chromatography) test is a specialized diagnostic tool used to identify and measure different types of hemoglobin in the blood. While most adults primarily have Hemoglobin A, certain genetic variations can lead to the production of abnormal types, such as Hemoglobin S (Sickle Cell), C, or E.

Physicians typically recommend this test for several critical reasons:

Diagnosis of Hemoglobinopathies: It is the gold standard for identifying disorders like Sickle Cell Disease or Thalassemia. If you are experiencing chronic anemia, fatigue, or unexplained jaundice, this test determines if an structural hemoglobin variant is the cause.

Prenatal and Preconception Screening: It is frequently advised for expectant parents or those planning a family to assess the risk of passing inherited blood disorders to their children.

Newborn Screening: Many regions use HPLC to ensure early intervention for infants born with conditions that could affect oxygen transport.

Investigating Anemia: When standard blood counts (CBC) show low hemoglobin or unusually small red blood cells (microcytosis), HPLC helps differentiate between simple iron deficiency and a genetic trait.
