Diagnosis of Sickle Cell Disease

Diagnosis of Sickle Cell Disease

Blood tests are used to diagnose sickle cell disease and sickle cell trait. They can be done on children or adults. Many states require newborn babies to be tested for sickle cell disease. This happens before they leave the hospital. Pregnant women can also have their unborn babies tested.

Tests include:

Hemoglobin electrophoresis —A small blood sample is taken. It is sent to a lab. The normal and abnormal hemoglobin are measured.

Sickledex test —A small blood sample is taken and sent to a lab. It looks at how many red blood cells have the sickle shape. A positive test means a person has either sickle cell trait or sickle cell disease.

Amniocentesis —Tests the fluid that surrounds the baby in the uterus. A small sample of the fluid is removed with a needle. It is then sent to a lab.
