Review: MaterniT21


Test Your Baby’s Chromosomes with MaterniT21

Nowadays there are several tests you can take in early pregnancy to detect abnormalities such as Down Syndrome. The most common is the NT ultrasound, which is non-invasive but has a high rate of false-positives and is not a diagnostic tool (it merely estimates the risk that the fetus may be affected). It is often the first choice for parents that will then choose a high-risk amniocentesis or CVS test if the results are positive. Both tests are considered high-risk because of the likelihood of miscarriage (around 1 in 300 or 1 in 360 respectively).
