some tests to find out risks-<br> Triple screen test or triple marker is a blood test capable of determining whether or not your baby may be at risk for birth defects, such as Spina Bifida, or chromosomal abnormalities, such as Down Syndrome (a common form of mental retardation). The test works by measuring levels of Alpha Fetoprotein (AFP), Human Chorionic Gonadotrophin (HCG), and Estriol in the blood. It is generally performed between the 16th and 18th weeks of pregnancy. Although the Triple Screen test can indicate abnormalities, it cannot diagnose actual problem with the fetus.&#160;<br> Nuchal translucency screening test- This screening test, also known as the nuchal fold scan, uses ultrasound to measure the translucency, or clear space, at the back of the developing fetus's neck. it is done between the 11th and 14th weeks of gestation (the period where this test is possible) and have determined the average size of the fluid at the back of a baby's neck each day during these three weeks.<br> Amniocentesis, a sample of the amniotic fluid that surrounds the fetus while it develops inside its mother is collected and analyzed so as to learn about your baby's genetic development or to check for infection. This optional test, available at 15 to 16 weeks gestation, may be performed for a variety of reasons, including advanced maternal age, previous problematic pregnancies, or a family history of genetic problems.<br> Chorionic Villus Sampling is another technique for testing the fetus' genetic development. CVS involves the removal of placental tissue. During the procedure a sample of the placenta is removed, either through the cervix (within the vagina) or through the abdomen as in an Amniocentesis. CVS is generally recommended for the same reasons as Amniocentesis, and carries many of the same risks of associated miscarriage. it is done between 10- 12weeks gestation...

thank u <u>dr</u>

there are tests to find out the risk ok having a baby with downs syndrome which is the the single largest cause of mental retardation. there is a scam that has to be done at 11to14weeks. along with this dual marker can also be done. later at 16 to 18weeks quadruple marker can be done.
