The Full form of CVS is Chorionic Villus Sampling.
What diseases does CVS test for?
CVS can help identify such chromosomal problems as Down syndrome or other genetic diseases such as cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. CVS is considered to be 98% accurate in the diagnosis of chromosomal defects.
What does CVS mean in nursing?

Transcervical CVS feels similar to a cervical screening test.
What diseases can be detected prenatally?
Screening can detect problems such as neural tube defects, chromosome abnormalities, and gene mutations that would lead to genetic disorders and birth defects, such as spina bifida, cleft palate, Down syndrome, Tay–Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, muscular dystrophy, and fragile X
What are the risks of CVS?
Risks of the procedure
- Cramping, bleeding, or leaking of amniotic fluid (water breaking)
- Infection.
- Miscarriage.
- Preterm labor.
- Limb defects in infants, especially in CVS procedures done before 9 weeks (rare)

Is CVS a disability?
Is CVS a disability? According to some research, approximately one-third of adult patients with CVS experience disability as a result of the condition. Some people with CVS are unable to walk or talk during episodes. A person may need to stay in bed throughout an episode or may even seem unconscious or comatose.
What is cyclic vomiting syndrome caused by?
