Prenatal tests
The Advantage of Choosing ovo prenatal
ovo prenatal allows you to complete all recommended pregnancy tests in one place. Our dedicated medical team is here to support, inform, and guide you through every stage of your pregnancy journey.

Prenatal Screening for Trisomies

Prenatal screening is a safe technique used to assess the risk that a fetus may have certain chromosomal abnormalities, including trisomy 21 (Down syndrome). Please note that the result indicates a probability and is not a definitive diagnosis.

Harmony: Non-Invasive Prenatal DNA Testing

A reliable, local, and approved solution

The Harmony test is a non-invasive prenatal screening (NIPT) performed through a simple maternal blood draw, starting from the 10th week of pregnancy. It allows for highly accurate detection of:

  • Trisomies 21, 18, and 13
  • Sex chromosome abnormalities (if prescribed by your healthcare professional)
  • Fetal sex

 

Harmony is the most validated prenatal screening test on the market, with a detection rate of over 99.9% for trisomy 21, and was the first test of its kind approved by Health Canada. Since 2023, ovo labo is the only laboratory in Quebec performing the Harmony test analysis. This translates to faster turnaround times, enhanced quality control, and the availability of a local team of accredited experts, ensuring a service that is fast, reliable, and accessible.

How the Test Works
  1. Book an appointment as early as 10 weeks (online or by phone)
  2. Blood draw at one of our service points
  3. Results available within 5 to 11 business days, sent by email

If the result shows a high risk, your physician or midwife will recommend a diagnostic test, such as an amniocentesis, to confirm the screening result.

Why Choose the Harmony Test?
  • Non-invasive: No risk to the mother and the fetus
  • Exceptional accuracy: Over 99.9% detection rate for trisomy 21
  • The most validated NIPT worldwide
  • Approved by Health Canada
  • Local analysis in Quebec: faster and more reliable
  • Option to determine baby’s sex in the first trimester
  • Covered by many private insurance plans
Helpful Tips
  • Combine with nuchal translucency ultrasound: Done around 12 weeks, this ultrasound remains essential for a complete first-trimester evaluation.
  • Suitable for all pregnancies: Harmony is designed for a wide range of situations, including twin pregnancies, IVF pregnancies, and those involving egg donation.
Fetal Fraction

A minimum threshold of 4% fetal DNA is required to ensure result accuracy. If this fraction is too low, the test may not yield a result, and a repeat sample may be recommended.
Factors such as gestational age, maternal weight, and certain medical conditions may affect fetal fraction.

Fetal Sex Testing

Would you like to know your baby’s sex early in pregnancy?

The SneakPeek test provides this information as early as week 6, with a 99.9% accuracy rate.

This is a recreational test and has no medical value. It does not replace a prenatal screening test or any ultrasound recommended by your healthcare provider.

 

  • When: Starting from 6 weeks of pregnancy
  • Results: 3 to 5 business days

Gestational Diabetes – Glucose Challenge Test

Gestational diabetes is an increase in blood sugar levels that usually occurs in the second trimester. The glucose challenge test helps screen for this condition.
Although it often resolves after childbirth, gestational diabetes may increase the mother’s risk of developing type 2 diabetes later on. Early detection is essential for proper care and monitoring.

Details of the tests
  • When: Typically between 24 and 28 weeks of pregnancy
  • Step 1 – Screening test (50g glucose challenge) – non-fasting
  • Step 2 – Confirmatory test (75g OGTT) – fasting required
What happens next?

If diagnosed, care may include nutritional counseling, blood glucose monitoring, physical activity recommendations, and possibly medication (insulin or oral agents).
Postpartum follow-up is also advised to assess glucose normalization and future diabetes risk.
