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.


Laboratory diagnosis of thalassemia requires a number of tests including red blood cell indices and Hb and DNA analyses. Thalassemic red blood cell analysis with an automated hematology analyzer is a primary screening for thalassemia since microcytosis and decreased Hb content of red blood cells are hallmarks of all thalassemic red blood cells.

Few laboratory tests can be used to detect and diagnose thalassemia: 1. Complete Blood Count (CBC) This form of diagnosis is an evaluation of cells in the blood. Aside from other things, CBC determines the number of red blood cells and how much hemoglobin is in them. with hepatosplenomegaly and thalassemia-like bone modifications to moderate microcytic hypochromic anemia. For the purpose of prevention and control of the clinically severe thalassemia diseases, i.e. hemoglobin (Hb) Bart’s, homozygous bthalasse-mia, and compound heterozygous bthalassemia/Hb E, molecular diagnosis and genetic counseling are Severe forms usually are diagnosed in early childhood and are lifelong conditions. Doctors diagnose thalassemias using blood tests.

Diagnosis is based on genetic tests and quantitative hemoglobin analysis. Treatment for severe forms may include transfusion, splenectomy, chelation, and stem 

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. Various blood tests are used to diagnose thalassemias: A complete blood count (CBC), which includes measures of hemoglobin and the quantity (and size) of red blood cells.

Red Cell Disorders Current Clinical Practice A Review of the Molecular Diagnosis of Thalassemia XIAOFENG GUa,* and YITAO ZENGb aDepartment of Haematology, Children’s Hospital, Fudan University, 183, Fenglin Road, Shanghai 200032, People’s Republic of China; bShanghai Institute of Medical Genetics, 24/1400, Beijing Road West, Shanghai 200040, People’s Republic of China A person with alpha thalassemia traits will have red blood cells that are hypochromic (paler) and microcytic (smaller) than that of a normal person. The red blood cell will also have a decreased mean corpuscular volume (MCV), which is a measurement of the average size of a single RBC. The person will also have mild chronic anemia.

The test is positive for Hemoglobin Bart's or fast bands. Many people with alpha thalassemia minor I have no idea. This usually comes to light during a routine complete blood count (CBC). Diagnosis of thalassemia and hemoglobinopathies requires a comprehensive evaluation combining red blood cell phenotypes, hemoglobin profiles, and DNA analysis.

(For more information, go to "Who Is at Risk for Thalassemias?") An algorithm for the use of molecular diagnostic testing for individuals with hemoglobin abnormalities. If the diagnosis of thalassemia or hemoglobinopathy is apparent based on hemoglobin studies and there are no genetic counseling issues, additional genetic testing is generally not needed. Quantitative HbA 2 determination is the most valuable test for β‐thalassemia carrier detection. Several methods are available: The most accurate, fast and simple are the michrochromatography and the cation exchange HPLC and capillary electrophoresis 20. 2020-12-10 · Definitive diagnosis of thalassemia and hemoglobinopathies requires a comprehensive workup from complete blood count, hemoglobin analysis, and molecular studies to identify mutations of globin Alpha-thalassemia can be diagnosed by blood analysis.
