In this article, the authors discuss the advantages associated with CVS. Chorionic villus sampling allows for an earlier decisions of termination of the fetus or of the total pregnancy, assuaging the couple’s apprehension of a receiving a disabled child. Depending on the maternal age, physical health of the mother, and placement of the incision the risk of miscarriage is anywhere from one to six percent. The sampling success is ninety-nine percent and the accuracy of diagnosis is high. With the transabdominal procedure, the discomfort and anxiety of CVS is less than the transcervical insertion. The time frame of the baby’s diagnosis is about seven to ten days as compared to other test which can take up to 4 weeks. Counseling is strongly suggested before having CVS done. Possible outcomes are discussed and the steps to take after the results are calculated. Couples that are concerned about potential abnormalities are offered information and assistance regarding their child’s possible condition. If there are any defects, selective reduction can be performed, reducing the number of pregnancy losses. Although CVS may be performed in multiple gestations, the first trimester is best for early detection and treatment.
