One of the most common genetic medicine procedures used today is in prenatal testing. The two types of prenatal testing procedures are screenings and diagnostic tests. A screening test evaluates the likelihood of the fetus having certain genetic disorders. A diagnostic test takes a sample of cells from the fetus or placenta to determine whether the fetus has any genetic disorders.
Why is it performed?
Prenatal testing allows a medical profession to examine whether a fetus is affected by any genetic disorder that could compromise safe childbirth as well as the future health of the child.
