Prenatal Screenings

There are several non-invasive prenatal screening (NIPS) tests on the market.

At Prelev, we work with Harmony and Verifi.

These prenatal tests are performed through a simple blood test that screens for trisomy 13, 18 and 21, sex chromosome abnormalities and fetal sex. They significantly reduce the need for invasive procedures such as amniocentesis and chorionic villus biopsy, which can cause miscarriage in about 0.5 to 1% of cases.

Approved by Health Canada, these fetal DNA tests available as early as 10 weeks of pregnancy also detect trisomy 21 with more than 99.9% accuracy.

A prescription from your doctor is required to perform these tests.

Make sure your baby is healthy in the first few weeks of life with prenatal screening tests!
