Prenatal genetic counselling.
Genetic concerns and indications for prenatal diagnosis are first recognized by the family physician. Review of personal, pregnancy and family history may indicate concerns beyond that of advanced maternal age. Amniocentesis is still the most frequently used modality for prenatal diagnosis, but detailed ultrasound is valuable for structural abnormalities, and chorionic villus sampling is now being tested as an alternative to amniocentesis.
