When do you test for sickle cell anemia?

When do you test for sickle cell anemia?

Sickle cell testing: In the United States, all states mandate testing for sickle cell anemia as part of their newborn screening programs. The test uses blood from the same blood samples used for other routine newborn screening tests. The test can show whether a newborn infant has sickle hemoglobin (from http://www.Nhlbi.Nih.Gov/health/health-topics/topics/sca/diagnosis.Html). ...Read more

Why is it more difficult to test for cystic fibrosis than it is to test for sickle-cell anemia?

Why is it more difficult to test for cystic fibrosis than it is to test for sickle-cell anemia?

More tests needed: Sickle cell disease is somewhat easier to diagnose. It is a genetic blood disorder caused by abnormal hemoglobin which tend to aggregate after unloading oxygen forming long, rod-like strictures that cause the red cells to assume a sickle shape. These sickle red cells cannot squeeze through small blood vessel and cause anoxia in organs.Cystic fibrosis is more complex to define resulting from failure to remethylate and shut off MUC5ac, an oncofetal gene which produces mucin in the fetus. Chest X ray and lung function tests may indicate problems from excess mucin. ...Read more

I know that the typical test for sickle-cell anemia is a hemoglobin electrophoresis, but will you be able to see the sickle shape of the blood cells?

I know that the typical test for sickle-cell anemia is a hemoglobin electrophoresis, but will you be able to see the sickle shape of the blood cells?

Yes: Sick led cells are readily seen on a peripheral blood smear. It's worth knowing that the irreversibly sick led cells that you see on a smear are not necessarily the ones that cause the problem. In order for a cell at risk for sickling to occlude the small blood vessels (capillaries), they first must be able to enter them. In other words they must be deformable. They become occlusive in the vessel. ...Read more

Are there other tests to determine sickle cell anemia risk if my husband is away serving in the military?

Yes: The first step is testing you for sickle cell carrier status. If not a carrier then no further testing needs to be done. If you are a carrier then the next step is check the father of the baby. If he is unavailable you could have his parents tested. If neither are a carrier then the father can not be a carrier either. If they are carriers then the fathers chances are 50% he is also. ...Read more
