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.
