Overview
Screening of carriers
Screening was first offered in 1975.[1] People who are known carriers of the disease often undergo genetic counseling before they have a child. A test to see if an unborn child has the disease takes either a blood sample from the unborn or a sample of amniotic fluid. Since taking a blood sample from a fetus has risks, the latter test is usually used. Currently, all 50 states in the USA require newborn screening for sickle cell disease.[2]
After the mutation responsible for this disease was discovered in 1979, the U.S. Air Force required African American applicants to test for the mutation. It dismissed 143 applicants because they were carriers, even though none of them had the condition. It eventually withdrew the requirement, but only after a trainee filed a lawsuit.
