CVS Test

CVS Test

Early prenatal diagnosis of genetic and chromosomal conditions

Chorionic Villus Sampling (CVS) is an invasive prenatal diagnostic test, usually performed between 11 and 13 weeks of pregnancy. It involves taking a small sample of placental tissue under continuous ultrasound guidance.

This placental tissue contains genetic material identical to the baby’s and is tested for chromosomal abnormalities and inherited genetic conditions. CVS allows early and definitive diagnosis, often earlier than amniocentesis.

Consult Dr. Sweta Bothra

Dr Sweta Bothra, Siliguri recommends CVS only when clearly indicated, such as high-risk screening results, known genetic disorders in the family, or abnormal early scan findings. The procedure is done carefully, with real-time ultrasound monitoring to ensure safety.

CVS may be advised when:

First trimester screening shows high genetic risk
There is a history of genetic or chromosomal disorders
Early diagnosis is important for timely decision-making
Parents need clear diagnostic answers early in pregnancy

Before proceeding, the procedure, benefits, and possible risks are explained thoroughly so parents can decide with confidence.

Frequently Asked Questions

Q. How is CVS different from amniocentesis?

CVS is done earlier in pregnancy and uses placental tissue, while amniocentesis is done later and uses amniotic fluid. Both provide diagnostic results.

Q. Is CVS safe for the baby?

When performed by an experienced fetal medicine specialist, CVS is considered safe. Risks are low and discussed clearly before the procedure.

Q. Does CVS confirm genetic conditions?

Yes. CVS provides definitive diagnostic information for many chromosomal and genetic conditions.

Q. Is the CVS procedure painful?

Most patients experience mild discomfort. The procedure is short and performed under ultrasound guidance.

Q. How long does it take to receive CVS results?

Preliminary results may be available within a few days, while detailed genetic reports may take one to two weeks.

Q. What precautions are needed after CVS?

Short rest and avoidance of heavy activity are usually advised for a day or two. Clear after-care instructions are provided.
