UK femcare-turned-gynaecological-health startup, Daye, has expanded its tampon-based home screening service to add STI testing. The startup is billing this “non-invasive screening” service for sexually transmitted infections as a “world first”.

The “STI Diagnostic Tampon” service uses Polymerase Chain Reaction (PCR) testing tech to detect the presence of pathogens. Daye is launching with the ability to test for five STIs — namely: Chlamydia, gonorrhoea, trichomonas, mycoplasma and ureaplasma — which were selected because they are the most common STIs. But more tests are planned.
