American College of Obstetricians and Gynecologists. 2011. Diagnostic tests for birth defects. Washington, DC: American College of Obstetricians and Gynecologists, 14 pp. Annotation: This patient education brochure describes diagnostic tests that can be done to detect birth defects before a baby is born. It discuses different types of common birth defects, including those caused by missing, damaged, or extra chromosomes such Down syndrome and Trisomy 18, and disorders caused by defective genes such as sickle cell disease, cystic fibrosis, and Tay-Sachs. The brochure discusses types of tests, including carrier tests, screening tests, and diagnostic tests, and explains important factors to consider in deciding whether to have them. Diagrams illustrating the differences between amniocentesis and chorionic villus sampling are included, along with a glossary of terminology. The brochure also includes a table listing some of the inherited and chronosomal disorders that can be diagnosed before birth.
