Who is this baby’s father? It’s a question a DNA lab promised to answer with “99.9% accuracy” — but instead, routinely identified the wrong dads. Investigative journalists Jorge Barrera and Rachel Houlihan track down the families whose lives were torn apart by these bad results and the story behind the Canadian company that stands by its testing and continues to operate today.

In 2015, a 20-something American named John learns he might be a father. A prenatal paternity test confirms it, and he quickly pivots from college student to family man. But eight months into the baby’s life, a second test reveals John is not the father, shattering his new reality. “How could I be that unlucky?”

Four years later, a Canadian college student named Corale needs to identify the father of her unborn baby. The 19-year-old turns to Viaguard Accu-Metrics for a prenatal paternity test. Like John, her world is rocked by tests that name the wrong dad. Unlike John, she starts asking questions and connecting dots. “Are there other people? Am I the only one?”

On the surface, Accu-Metrics was making headlines and growing strong. But two former employees paint a troubling picture of what was going on inside, from staff who don’t seem properly trained to a stream of customers complaining about test results. Plus, the questions they were instructed to ask just didn’t seem right…

After years of expansion into different DNA services, controversies around the company begin to surface — publicly. There’s a lawsuit against the company, journalists (including our co-host Jorge Barrera) start sniffing around; and a poodle is falsely identified as an Indigenous person. Meanwhile, prenatal paternity testing quietly disappears from the services on the Viaguard Accu-Metrics website.

What’s really going on inside Accu-Metrics? Co-host Rachel Houlihan goes undercover, posing as a mother who needs a paternity test. Once inside, she meets face to face with the company’s owner, Harvey Tenenbaum. She also connects with an ex-employee who reveals what he witnessed in the lab.

In September 2024, a senior employee at Viaguard Accu-Metrics is sentenced for running an unrelated $6 million hair-testing scam. Will this development prompt the police to investigate his former employer as well? Will it finally push Tenenbaum to comment on the record? And what options remain for John, Corale and the other customers living with the long term impact of their bad results?
