Quizplus · Accepted Answer

The doctor has asked Penny Wills to take the triple screen test, which is a type of maternal blood screening. This test is used to detect any abnormalities in the developing fetus by analyzing certain hormones and proteins in the mother's blood. It is a non-invasive procedure and does not pose any risks to the baby. Therefore, option A is the correct choice. Option B, noninvasive prenatal diagnosis, involves more advanced testing that is typically reserved for high-risk pregnancies. Option C, chorionic villus sampling, is a more invasive diagnostic test that involves removing a small sample of tissue from the placenta. Option D, ultrasound sonography, is a diagnostic tool used to create images of the developing fetus but is not specifically a prenatal diagnostic test.
