Thalassemia Test

Thalassemia Test

  • A complete blood count (CBC): This can check levels of haemoglobin and the level and size of red blood cells.
  • A reticulocyte count: This measures how fast red blood cells, or reticulocytes, are produced and released by the bone marrow. Reticulocytes usually spend around 2 days in the bloodstream before developing into mature red blood cells. Between 1 and 2 percent of a healthy person’s red blood cells are reticulocytes.
  • Iron: This will help the doctor determine the cause of anaemia, whether thalassemia or iron deficiency. In thalassemia, iron deficiency is not the cause.
  • Genetic testing: DNA analysis will show whether a person has thalassemia or faulty genes.
  • Prenatal testing: This can show whether a fetus has thalassemia, and how severe it might be.
  • Haemoglobin electrophoresis (Hemoglobinopathy (Hb) evaluation). This test assesses the type and relative amounts of haemoglobin present in red blood cells. Haemoglobin A (Hb A), composed of both alpha and beta globin, is the type of haemoglobin that normally makes up 95% to 98% of haemoglobin in adults. Hemoglobin A2 (HbA2) is usually 2% to 3% of haemoglobin in adults, while haemoglobin F usually makes up less than 2%.
