Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like fatigue, pain, or frequent infections, or if you have a family history of blood disorders. It may also be used during pregnancy to screen for certain genetic conditions.
What to Expect During the Test
A small blood sample is taken from your arm. The sample is then analyzed in a lab to identify the genetic makeup of your hemoglobin. Results are typically available within a few days.
How the Results Are Interpreted
The test result will show the specific hemoglobin variant you have. For example, it may indicate a variant like HbS (associated with sickle cell disease) or another known variant. Your healthcare provider will discuss these findings with you.
Common Conditions Linked to This Test
This test is primarily used to diagnose or confirm inherited blood disorders such as sickle cell disease, thalassemia, or other hemoglobinopathies. It can also be part of prenatal screening for genetic conditions.
