Chorionic Villus Sampling (CVS)
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.
