Fractions of hemoglobin A, A2, F, H, E, and other variants are measured. Hemoglobin analysis by hemoglobin electrophoresis or high performance liquid chromatography is used. DNA testing is the only way to determine silent alpha thalassemia trait and the related hemoglobin trait called hemoglobin Constant Spring. DNA testing may also be necessary in order to allow for the option of prenatal testing. Erythrocyte porphyrin tests may be used to distinguish an unclear beta thalassemia minor diagnosis from iron deficiency or lead poisoning. Individuals with beta thalassemia will have normal porphyrin levels, but those with the latter conditions will have elevated porphyrin.

Red blood cells that are varied in size and shape 5.

A reticulocyte count (a measure of young red blood cells) may indicate that your bone marrow is not producing an Studies of A blood test can be carried out at any point to diagnose thalassaemia if a child or adult has symptoms of thalassaemia and the condition was not picked up earlier on. Testing for the thalassaemia trait. A blood test can be done at any time to find out if you have the thalassaemia trait and are at risk of having a child with thalassaemia. The primary molecular test available for alpha thalassemia detects common mutations (e.g., deletions) in the two alpha genes HBA1 and HBA2. Each person has two copies of each of these genes, called alleles , in their cells, one from their mother and one from their father.

The study included 256 β-thalassemia (β-thal) carrier couples who were referred to the Zahedan Prenatal Diagnosis Center to take the PND test and 47 β-thal carrier couples who already had a newborn with β-TM and had not taken the PND test. Diagnosis: Diagnosis in infants takes place through new born screening for Alpha thalassemia. In most of cases, diagnosis for Hb Bart’s hydrops fetalis takes place before birth.
