CVS (Chorionic Villus Sampling)

Results

Chorionic villus sampling (CVS) is a test done during early pregnancy that can find certain problems with your baby (fetus).

Cells from your baby are looked at carefully for the proper number and arrangement of the genetic material (chromosomes) that show genetic diseases. Normally there are 46 chromosomes in each cell, arranged in 23 pairs. Chromosomes also tell the sex of your baby. It may take 1 to 2 weeks to get CVS results.
