The top non-invasive prenatal genetic tests in the market today and their sensitivity

Parents-to-be want the comfort of knowing that their developing baby is free of genetic defects.

These non-invasive prenatal genetic tests, using a drop of the mothers’ blood, test for any chromosomal abnormalities in the developing baby. They are about as sensitive as tests used currently and less risky than amniocentesis and others.

The tests check for abnormalities such as Down’s syndrome, Klinefelter’s (XXY) syndrome, triple X syndrome, Patau’s syndrome etc.

Sequenom MaterniT21 Plus checks for more abnormalities than Ariosa Harmony, Natera Panorama and Verinata verifi are in the middle.

The tests can be performed in the first trimester.

Currently, these tests are considered screening tests only. If they give a positive result, amniocentesis still needs to be performed for full confirmation.
