Results: The answers to the multiple choice question assessing how they look back on their initial expectations regarding the exact meaning of the triple test revealed that less than one half reported that it concerned the identification of 'a higher risk of carrying a child with Down syndrome (DS)' Triple Test Screening for Down Syndrome: An Egyptian-Tailored Study Hazem S. Abou-Youssef*, Manal M. Kamal, Dina A. Mehaney Clinical and Chemical Pathology Department, Faculty of Medicine, Cairo University, Cairo, Egypt Abstract Background:The incidence of Down syndrome (DS) in Egypt varies between 1:555 and 1:770 and its screening by triple test Second trimester screening is traditionally based on the triple test. In this test, three maternal serum markers [α-fetoprotein (AFP), chorionic gonadotropin (CG) and unconjugated oestriol (uE3)] are measured and used to modify the women's prior risk (based on her age) to yield a patient specific DS risk [5]

Given that a test result is negative, show that the probability the fetus actually has Down syndrome is P(D | NEG) = 0.0015 It tests the levels of three components in the mother's blood which have come from the placenta: beta HCG (human chorionic gonadotrophin) estriol & AFP (alpha-fetoprotein) This test is actually a screening test which means that it can tell you whether the pregnancy has a high risk of Down syndrome or a low risk of Down syndrome

We present an approach that can be used to estimate the expected additional value of the triple test for each pregnant. Amniocentesis was performed to the patients with high test results for trisomy 21 and 18.
