1. What is Chorionic Villus Sampling (CVS) and how is it performed?
A) It is a prenatal test used for genetic analysis.
B) It involves taking a small sample of cells from the placenta.
C) It can be conducted only after the 10th and before the 13th week of pregnancy.
D) Results are typically available within one to two weeks.
Answer:
The correct statements regarding Chorionic Villus Sampling (CVS) are B) It involves taking a small sample of cells from the placenta and C) It can be conducted only after the 10th and before the 13th week of pregnancy.
Chorionic Villus Sampling (CVS) is a prenatal test used to analyze the baby's chromosomes and DNA. It involves taking a small sample of cells from the placenta, specifically the chorionic villi, which are finger-like projections on the placenta. These cells contain the same genetic material as the fetus and can be analyzed to detect genetic disorders and chromosomal abnormalities.
The optimal time frame for performing CVS is between the 10th and 13th week of pregnancy. The procedure involves inserting a thin needle or catheter through the mother's abdomen or cervix to reach the placenta and collect the cells.
After the CVS procedure, the collected cells are analyzed in a laboratory to obtain the baby's genetic information. The results of CVS are typically available within one to two weeks. It is important to note that CVS carries a small risk of miscarriage, although the risk is generally low.
