What are the different types of prenatal screening?
parents to be selected will perform a number of prenatal screening tests. Some tests are designed to diagnose a congenital defect, while others measure only the level of risk that exists for certain health conditions. If screening results reveal a high level of risk of health problems, then the woman and her partner have to decide whether they want to perform further testing. The woman will be asked to provide a urine sample at each visit. This sample will be used for screening for elevated levels of proteins that indicate preeclampsia, and sugar levels that would cause concerns about gestational diabetes.
Pre-eclampsia is a hypertension related to pregnancy and can be very serious, even life-threatening, for the mother and child, unless controlled. Other signs preeclampsia are sudden, serious headaches and swelling in the legs and legs. Gestational diabetes occurs when the mother's body is unable to produce enough insulin to suit his own and needs of the child. Fatigue,Excessive thirst and blurred vision are symptoms of this condition. A pregnant woman who is experiencing any of these symptoms should immediately see her healthcare provider.

The two -piece test includes a blood sample taken from a pregnant woman, along with an ultrasound examination of the developing fetus.

It can also be used to diagnose cardiac abnormalities, but is not used to determine whether a child has defects of a nerve tube such as bifida spina.
Further tests of prenatal screening Aznova are used for diagnostic purposes. Amniocentesis is an invasive test where a small amount of amniotic fluid is removed from the uterus. It is a highly effective way of diagnosing congenital defects such as Down syndrome, cystic fibrosis, muscle dystrophIE and sickle disease.
