A
Carrier testing is done to determine whether individuals carry the genes for particular diseases. These genes can be passed to one's offspring, leading to clinical disorders. Couples from specific racial and ethnic groups are often advised to have carrier testing before conceiving.
Diagnostic testing identifies a specific gene that may be causing a health condition now or could cause one in the future.
Genetic counseling may be needed pending the results of the carrier testing.
Genetic variability is not one of the main types of genetic testing offered.
