“The PrenaTest® is a safe and reliable non-invasive prenatal test (NIPT) for the determination of fetal trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), trisomy 13 (Patau syndrome), maldistributions of sex chromosomes X and Y (Klinefelter, Turner, triple X and XYY syndrome) and the 22q11.2 microdeletion (DiGeorge syndrome). The PrenaTest® can also be performed in the case of a twin pregnancy, following fertility treatment, for example following IVF or ICSI, as well as after egg donation. If desired, you can also learn whether you are expecting a girl or a boy.”-Lifecodexx. It takes on average five days to obtain the test results.
The picture shows the nuchal translucency measurement during the 11th to 14th week of pregnancy. Nuchal translucency is the normal fluid-filled subcutaneous space identified at the back of the fetal neck. Increased nuchal translucency is a risk factor for Trisomy 13,18,21 and other malformations.
In contrast to nuchal translucency this is an invasive procedure used in prenatal diagnosis to look for chromosomal abnormalities and fetal infections. With the aid of ultrasound-guidance the uterus sac is punctures in an area away from the fetus and 15-20ml of amniotic fluid is extracted for further analysis.
Due to the fast development, modern ultrasound can produce very plastic and reality-like pictures of the baby. The main clinical use is the real-time analysis of the heart movement.
