PATHOLOGY

Detailed explanation-1: -Carrier testing can be used to help couples to learn if they carry-and thus risk passing to their children-an allele for a recessive condition such as cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.

Detailed explanation-2: -What process can prospective parents use to determine if they are carrying recessive alleles for disease? Genetic testing.

Detailed explanation-3: -Some women choose to complete carrier screening during pregnancy. Carrier screening tests require a sample of an individual’s blood, saliva, or tissue, usually from the inside of the cheek. The parent who is most likely to be a carrier is typically tested first.

Detailed explanation-4: -Diagnostic tests. Amniocentesis, chorionic villus sampling (CVS) and ultrasound are the three primary procedures for diagnostic testing. Amniocentesis is the test we most commonly use to identify chromosomal problems, such as Down syndrome.

Detailed explanation-5: -Carrier screening is a type of genetic test that can tell you whether you carry a gene for certain genetic disorders. When it is done before or during pregnancy, it allows you to find out your chances of having a child with a genetic disorder. What is a recessive disorder?
