PrenaTest® ­– Europe's first non-invasive prenatal test (NIPT)

Non-invasive examination for the determination of the fetal trisomies 21, 18 and 13 such as Klinefelter syndrome, Turner syndrome, Triple X syndrome, XYY syndrome and a 22q11.2 microdeletion

Starting from the ninth week of pregnancy (9+0 p.m.), the PrenaTest® is able to determine trisomy 21, trisomies 21, 18 and 13, gonosomal aneuploidies (Turner, triple X, Klinefelter, and XYY syndromes) as well as the 22q11.2 microdeletion, associated with DiGeorge syndrome and velo-cardio-facial syndrome (Shprintzen syndrome), as requested, in blood samples from expectant mothers at risk for fetal aneuploidies. If desired, the gender of the child may also be determined. With its low false-positive rate the PrenaTest® provides precise information for the early diagnosis of abnormalities, thus potentially reducing the number of unnecessary invasive examinations in women who are unaffected. As a result, it acts as a supplement to the non-invasive prenatal diagnostic techniques already in use, but – in comparison with invasive examination methods – it does not involve the risk of procedure-related miscarriage.
