CVS (Chorionic Villus Sampling) tends to be considered slightly riskier than amniocentesis in terms of procedure-related miscarriage rates. CVS is typically performed between 10 to 13 weeks of pregnancy and carries a miscarriage risk of about 0.1% to 0.3%. In contrast, amniocentesis is done between 15 to 20 weeks and has a slightly lower risk, around 0.1% to 0.2%. Deciding between the two should involve a discussion with a healthcare provider, considering personal risk factors, genetic concerns, and timing.
