Noninvasive Method for Prenatal Diagnostics


With the DNA test Prenatest the fetal trisomies 21 (Down Syndrome), 13 (Patau Syndrome) and 18 (Edwards Syndrome) can be detected with a high degree of accuracy and in a non-invasive way. For the purpose, venous blood is taken from the pregnant woman and is then analyzed by using next generation sequencing techniques. With its low false-positive rate of 0.5%, this test allows early diagnosis of fetal malformations and therefore reduces the number of unnecessary invasive examinations of pregnant women, without any risk for the unborn child. PrenaTest is an innovative non-invasive method for prenatal diagnosis, which complements perfectly the common prenatal examinations and in contrast to invasive methods such as amniocentesis it does not carry the risk of procedure-related fetal losses. In accordance with the recommendations of the prenatal medicine specialists, positive test results need to be further clarified diagnostically by means of an invasive examination. PrenaTest is carried out after the 12 week of pregnancy and is recommended for women with a higher risk of having a baby with Down Syndrome, Patau Syndrome or Edwards Syndrome. The pregnant woman, who has opted to undergo the PrenaTes, should consult her gynecologist and/or medical genetics specialist, to be able to take the most appropriate decision for the development of her pregnancy.
