The at-home STI test for chlamydia and gonorrhoea has been pulled from Australian shelves after failing to detect infections, raising serious public health concerns. The Therapeutic Goods Administration (TGA) issued a six-month suspension to Touch Biotechnology following a review that found the device "is not reliable… and poses a high risk for false negative results for users." This development has left many Australians questioning the safety and accuracy of home testing kits.
What Happened with the At-Home STI Test?
The product, which first hit pharmacy shelves in December 2024 at a retail price of $24, involves a vaginal swab placed in a container with testing solution. The TGA was alerted by a health service in May about false negative results affecting an unspecified number of patients. The regulator stated it "does not have a reliable estimate of how many users may have received false negative results." Touch Biotechnology's general manager, Mazz Gencer, acknowledged the TGA's action and has ceased supply pending further verification and performance testing.

Why Accuracy Matters for STI Testing
False negative results can lead to untreated infections, which may cause serious health complications such as pelvic inflammatory disease, infertility, and increased risk of HIV transmission. The TGA's suspension highlights the critical need for reliable testing methods. At the time of approval, Touch Biotechnology claimed its product correctly identified more than 99% of positive cases for both chlamydia and gonorrhoea when compared against urine PCR testing, and did not produce any false positives. However, the TGA review contradicted these claims.
