Give yourself peace of mind with our prenatal screening tests. Allowing detection of the main trisomies (13, 18 and 21), as well as many other conditions.

 

All the tests offered by Prenato are free of risk for the mother and the fetus. This test can be done as early as the 10th week of pregnancy through a simple and unique blood sample. Some tests can also reveal the baby’s sex, as early as the 10th week of pregnancy.

 

*A prescription is required for these tests.

 

 

Prenato offers you two options : Serum markers testing and fetal DNA testing.

 

PRENATO SCREENING – SERUM MARKERS

  • Available from the first trimester, between weeks 11 and 14
  • Results in 3 to 5 working days
  • A single blood test
  • Detects up to 98% of trisomies 18 and 21
  • Analyzed in Quebec
  • Fetal DNA screening for trisomies 13, 18 and 21 is offered free of charge in cases of risk ≥ 1/2500 for trisomy 21 and ≥ 1/100 for trisomy 18

 

This screening test is done by taking a simple and unique blood sample, and is based on the serum markers: hormones produced by the fetus or the placenta, passing into the mother’s blood flow during pregnancy. After the blood sample is taken, the analysis allows us to assess the risk of the main trisomies 18 and 21 for the fetus. The risk calculation is made by combining the age of the patient, the nuchal translucency measure taken at the first semester, and the 4-hormone analysis during the first semester. A nuchal translucency measurement is required to obtain the result. This service is available at Prenato by appointment.

This screening test is performed using an analysis of fetal DNA through a simple blood draw from the mother.
