What is amino synthesis test..why it is done? 

A needle is usually inserted through the mother's abdominal wall or at the end of the vagina, and through the wall of the uterus into the amniotic sac. With assistance from ultrasound, a physician aims towards an area of the sac that is away from the fetus and extracts a small amount of amniotic fluid for testing.The puncture heals, and the amniotic sac replenishes the liquid over a day or so. After the amniotic fluid is extracted, the fetal cells are separated from it using a centrifuge, and the fetal chromosomes are examined for abnormalities. Various genetic testing may be performed, but the three most common abnormalities tested for are Down syndrome, Trisomy 18 and spina bifida.  https://ph.answers.yahoo.com/question/index?qid=20081124064248AApVBhZ

Rubella

Women who are planning to become pregnant should make sure they have a pre-pregnancy blood test to see if they are immune to rubella. Most women of childbearing age were vaccinated as children with the MMR vaccine, but they should confirm this with their doctor. If they need to get vaccinated for rubella, they should avoid becoming pregnant until one month (28 days) after receiving the MMR vaccine and, ideally, not until your immunity is confirmed by a blood test.
