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?”

A legal note: Over the course of this podcast, a number of allegations are made against Viaguard Accu-Metrics and its employees. When asked, company owner Harvey Tenenbaum said he stands by the test, and that any errors were caused by customers during sample collection.
