Adnà offers legal paternity tests in Greater Montréal: $325 before taxes, sample collection at our Rosemont office or at your home, each person’s identity verified, results in 5 to 7 business days.
It is a test where an independent person collects the samples, verifies each participant’s identity and documents the chain of custody of the samples. This is what allows the result to be presented to a court or a notary. The analysis is the same as for the informational test: 22 genetic markers, read by a Canadian laboratory accredited to ISO/IEC 17025:2017 by the Standards Council of Canada (file no. 15873, official scope of accreditation).
Taxes extra. Example: $325 + GST and QST = $373.67. All our prices: how much a paternity test costs in Quebec.
The legal test is designed to be presented to a court or a notary. However, it is the court that decides how much weight to give a piece of evidence: if proceedings are under way, check with your lawyer before ordering.
Monday to Friday, 9 a.m. to 5 p.m., at (514) 233-5456. Service in French, English and Spanish.
