What is the cause of sickle cell anemia in fetus?

You may be confused. Fetuses do not suffer from sickle cell anemia in utero because they have a different type of hemoglobin (fetal) that is unaffected even in individuals destined to have sickle cell disease later in life. Affected fetuses come from affected or carrier parents and sickle cell disease is a genetic condition without cure at present. See a genetic counselor to discuss these issues in detail. Read more...
Defective genes. The chromosomes contain genes which have the instruction on how the work of the body is done. In SS disease, each parent has given the fetus a defective gene, so defective blood cells would be made after baby is born & becomes an air breather. Before then its red cells are made using other instructions. The parents are unaffected because each has one normal gene that can make good blood cells. 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.

Only blood tests. People with sickle cell anemia usually are identified very early in childhood, due to symptoms. Sickle cell carriers, have no symptoms and can only be identified by blood test. Inheriting sickle cell disease requires getting a sickle gene from both parents. If you are a carrier and your husband is too, there is a 1 in 4 chance of a child inheriting the disease.

When do you test for sickle cell anemia?

Diagnosis. You only need to check for sickle cell disease at first diagnosis or if both parents are known to be sickle-cell patients. The test is for abnormal hemoglobin molecules caused by a genetic mutation. If you are a carrier or have the disease, that will be with you for life. Subsequently, blood counts need to be done regularly if you get sickle cell episodes. Read more...
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...
