Invasive Diagnostic Tests
Invasive prenatal testing is performed to diagnose genetic or chromosomal conditions in the fetus during pregnancy. The two most commonly used methods are Chorionic Villus Sampling (CVS) and Amniocentesis. While these procedures are highly informative, they carry a small risk of miscarriage or complications. CosmoMed Fertility Center offers advanced non-invasive testing options that may help determine whether invasive testing is necessary. If you are considering CVS, Amniocentesis, or other prenatal testing methods, schedule a consultation at CosmoMed Fertility Center to discuss the safest approach for your pregnancy.

Chorionic Villus Sampling (CVS)
CVS involves sampling the chorionic villi, the placental tissue that shares the same genetic makeup as the fetus. Using ultrasound guidance, a thin needle is inserted through the abdomen to collect a small tissue sample. Patients may feel slight abdominal discomfort afterward. When CVS is performed to assess the risk of Down syndrome, results are typically available within 2–3 days, while testing for other rarer conditions may take longer. Your physician will provide a clear timeline for receiving your results.
Amniocentesis
Amniocentesis examines cells from the amniotic fluid, which surrounds the fetus. Since these cells originate from the baby, they reflect the fetal chromosomes. The procedure is performed using a thin, ultrasound-guided needle to collect a small amount of fluid. Mild abdominal discomfort may be experienced afterward. When used to screen for Down syndrome, results are usually available in 2–3 days, while analysis for other genetic conditions may require additional time. Your physician will inform you when the results can be expected.
