Question

Name the blood test which can detect if a person is a carrier of thalassemia
A. Prenatal testing
B. A complete blood count
C. A Reticulocyte count
D. All of these

Answer 1

Hint:
Many birth defects, including those that are genetic illnesses, can be detected during prenatal screening tests to determine if your kid is more or less likely to have them. These examinations include prenatal cell-free DNA screening, blood tests, and a particular kind of ultrasound. In order to determine whether your unborn child is at risk for certain birth problems like Down syndrome and heart defects, this screening test comprises a blood test and an ultrasound.
Usually, multiple marker screening includes this. The triple screen test and the quad screen test are two different types of multiple marker screening. Alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol are the three chemicals that the triple marker screen searches for in the fetal blood or placenta.

Complete answer:
To identify thalassemia, your doctor may run a number of blood tests, including a complete blood count (CBC) that counts red blood cell amount (and size) as well as haemoglobin. Thalassemia patients have fewer normal red blood cells and less haemoglobin than average. Blood tests can count red blood cells and identify any abnormalities in their size, shape, or colour. DNA analysis performed on blood samples can also be used to search for altered genes.
So, all of these options are the tests that can detect if a person is a carrier of thalassemia.

Option ‘D’ is correct

Note:
A higher than average reticulocyte count could be a sign of anaemia because red blood cells degrade more quickly than they should (hemolytic anaemia) Bleeding. Blood condition in a newborn or fetus (erythroblastosis fetalis). The purpose of the test is to ascertain whether the bone marrow is producing red blood cells at a pace that is appropriate. The quantity of reticulocytes in the blood is a measure of how quickly the bone marrow is producing and releasing them.
In a peripheral blood smear test, a hematopathologist looks at a drop of blood under a microscope to look for any unusual alterations in the quantity, composition, shape, maturity, or appearance of different blood cells.
