New Prenatal Test Offers Early, Low-Risk and Accurate Results Using blood rather than amniotic fluid has been invented and now most of LABORATORIES will start doing this test because easy and without any damage to Foetus or baby inside womb as here no amniotic fluid or fluid of baby of chorionic villus biopsy or placental biopsy is needed as it may cause abortion or infection to baby.It will eliminate now a days done DOUBLE MARKER OR TRIPLE MARKER OR QUADRPLE MARKER STUDY BEING DONE WITH USG OF BABY BY EXTRAPLOTTING ON GRAPH CHROMOSAL OR METABOLIC ABNORMALITY OR BIRTH DEFECT OF BABY .
BUT as it is DNA TEST ,so CHROMOSOMAL TESTS WILL BE DONE SO FOETAL BABY SEX MAY BE KNOWN SO PNDT ACT WILL COME IN FORCE AND IN INDIA laboratory will not reveal sex chromose study of Baby.
A test currently undergoing FDA approval should increase screening accuracy for Down syndrome and other genetic defects to nearly 100 percent while eliminating risk of abortion for such testing.
The Panorama test developed by Natera, Inc. eliminates risk for mothers and children by testing the fetus’s DNA found in the mother’s bloodstream rather than extracting amniotic fluid from the mother’s womb to test DNA. After extracting the blood, scientists separate the child’s DNA from the mother’s and use complex computer algorithms to check all 23 pairs of chromosomes. This test is able to determine if the child has the correct number of chromosomes. Many genetic defects come from having one too many (trisomy) or too few (monosomy) copies of a chromosome. Knowing about these defects like Trisomy 21, Down Syndrome, helps mothers and doctors determine the best prenatal care. Additionally, the Panorama test allows these tests to be performed much earlier than previous tests—accurate results as early as 9 weeks gestational age.

These prenatal tests are purely optional, though usually encouraged. However, some mothers have very difficult decisions to make after learning so early that their children have genetic defects that usually result in infant death or a life full of difficult care and mental disability. In some cases, women have opted to terminate the pregnancy because the tests showed such severe genetic defects. Other mothers have found great comfort knowing that they had time to mentally, emotionally, and logistically prepare for a child with special needs.
