Chorionic villus sampling only tests for chromosomal abnormalities such as Down’s syndrome. Your doctor will still advise you to undergo alphafetaprotein (AFP) testing at about 15 weeks to test for neural tube defects, followed by an ultrasound at about 22 weeks to test for nonchromosomal abnormalities.
