Prenatal Diagnosis Terms
false negative rate - The proportion of pregnancies that will test negative given that the congenital anomaly is present.
false positive rate - The proportion of pregnancies that will test positive given that the congenital anomaly is absent.
negative predictive value - The probability that a congenital anomaly is absent given that the prenatal screening test is negative.
positive predictive value - The probability that a congenital anomaly is present given that the prenatal screening test is positive.
pre-implantation genetic diagnosis - (PGD) a screening procedure for embryos produced through in vitro fertilisation (IVF) for genetic diseases that would generate developmental abnormalities or serious postnatal diseases.
prenatal screening sensitivity - (detection rate) The probability of testing positive on a prenatal screening test if the congenital anomaly is present.
prenatal screening specificity - The probability of testing negative on a prenatal screening test if the congenital anomaly is absent.
