To the Editor Dr Kuppermann and colleagues1 reported a decrease in invasive prenatal testing, as well as patients making more informed choices, when randomized to receive a computerized, interactive decision-support guide. The control group received no specific counseling or information on screening and diagnostic tests.
The guideline from the Royal College of Obstetrics and Gynaecologists on amniocentesis and chorionic villous sampling recommends that all women undergoing these procedures provide written informed consent prior to testing. This consent should include risk of miscarriage associated with invasive testing.2
