WHEN IS CVS DONE?

CVS is usually done between 11 - 15th week of pregnancy.

WHEN WILL THE CVS TEST RESULTS BE AVAILABLE?

Usually it takes about 2 - 3 weeks. Upon request, a rapid test can provide a preliminary report in 3 working days

CAN ALL BIRTH DEFECTS BE DETECTED BY CVS?

No. CVS can detect almost all known chromosomal disorders. However, birth defects not due to chromosomal abnormalities such as certain genetic syndromes cannot be detected through this test.

WHO SHOULD CONSIDER CVS?

Women whose First Trimester Screening or Maternal Serum Screening or Non Invasive prenatal testing test results shows a “High Risk” for Trisomy 21 or 13 or 18.
Women who know that they or their partners are carriers of a known genetic disease.
Women who had an early ultrasound report shows that the fetus has structural defects which are associated with chromosomal disorders.
Women who have had a child with Down Syndrome or other chromosomal disorders.
Women who know that they or their partners have an unusual chromosome arrangement.

IS CVS SAFE?

CVS is a safe, low risk procedure when done by experienced medical experts. The risk of miscarriage following the test is reported to be 1%.
