Quick Summary

Health Canada has issued a safety notice and recall for HCG one-step pregnancy tests manufactured by Innovacon Inc., warning that these tests may produce false positive results due to detecting low levels of human chorionic gonadotropin (HCG) in non-pregnant individuals, particularly those experiencing perimenopause. The agency advises customers to be cautious when interpreting their test results and suggests waiting until after a missed period for more accurate outcomes.

Story summary

Health Canada issued a safety notice on February 13, recalling HCG one-step pregnancy tests from Innovacon Inc. due to concerns of false positive results. The agency warned that the product may detect low levels of human chorionic gonadotropin (HCG), even below stated sensitivity thresholds, leading to inaccurate results for non-pregnant individuals. This recall affects a critical diagnostic tool used during early pregnancy detection, as HCG is produced in the placenta and its levels typically double every two to three days post-implantation. According to the Mayo Clinic, waiting one or two days after missing a period can increase test accuracy by ensuring sufficient HCG for detection. Most such tests provide results within minutes, but users are advised to carefully interpret outcomes given these potential inaccuracies.
