chorionic villus sampling

A doctor performs chorionic villus sampling on a pregnant patient.

Definition

Noun: 1. A prenatal diagnostic procedure: A medical test performed during early pregnancy to assess the health of the developing fetus. It involves taking a small sample of tissue from the chorionic villi, which are finger-like projections on the chorion (part of the placenta) that share the fetus's genetic makeup. This tissue is then analyzed in a laboratory.

Examples of Usage
  • Noun:
    • The doctor recommended chorionic villus sampling to check for chromosomal abnormalities.
    • Chorionic villus sampling is typically performed between the 10th and 13th weeks of pregnancy.
    • After receiving the results from the chorionic villus sampling, the couple had more information to discuss with their genetic counselor.
Advanced Usage

    • The chorionic villi contain cells that can be analyzed for genetic information.
  • Amniocentesis (n): A different prenatal diagnostic test performed later in pregnancy, which analyzes amniotic fluid instead of placental tissue.
Synonyms
  • Prenatal diagnostic test: A general term for procedures like chorionic villus sampling and amniocentesis.
  • Prenatal screening: A broader category that includes both diagnostic tests (like CVS) and less invasive screening assessments.
Related Phrases
  • Genetic testing: The laboratory analysis performed on the sample obtained from chorionic villus sampling.
    • Chorionic villus sampling allows for early genetic testing.
  • Birth defect detection: One of the primary purposes of the procedure.
    • A key advantage of chorionic villus sampling is early birth defect detection.
