How accurate is CVS test for gender?

CVS is considered to be 98% accurate in the diagnosis of chromosomal defects. The procedure also identifies the sex of the fetus, so it can identify disorders that are linked to one sex (such as certain types of muscular dystrophy that occur most often in males).

What chromosomal abnormalities does CVS test for?

During a CVS, some cells from the chorionic villi are removed and tested for chromosomal abnormalities such as Down syndrome, Tay-Sachs disease, and fragile X syndrome.

What genetic disorders can be detected by CVS?

CVS can help identify certain genetic diseases, including problems with chromosomes….What diseases or disorders does chorionic villus sampling identify?

• Down syndrome, or trisomy 21.
• Cystic fibrosis.
• Sickle cell disease.
• Tay-Sachs disease.
• Trisomy 18, or Edward syndrome.

What can chorionic villus sampling detect?
