Regular STI testing is an important part of sexual health. The Daye STI Screen is a non-invasive, at-home test that uses a tampon-style sample collection for comfort and ease. Simply insert the diagnostic tampon, wear it for 20 minutes, then return it to Daye’s accredited laboratory using the prepaid kit.

You do not need to be on your period, and it can be used during menopause, pregnancy or while on contraception. Samples are analysed using molecular PCR testing, a highly sensitive method that detects the genetic material of specific infections. Results are available online within 5–10 days, with access to professional guidance and follow-up support if needed.

Daye's vaginal microbiome test kits offer a discreet and practical way to better understand your gynaecological health without needing a clinic visit. Using advanced PCR analysis, they provide a comprehensive assessment of vaginal health from the comfort of your home. Instead of traditional swabs, the tampon-based collection method gathers fluid from the entire vaginal canal for broader sampling. The applicator design helps reduce contamination risk and makes the process more familiar and comfortable. By combining high-sensitivity laboratory technology with full-canal sampling, Daye delivers more detailed microbiome insights than standard screening approaches.

Daye exists to raise the standard in gynaecological health — creating innovative products and services designed to fit seamlessly into modern life. Built on the belief that healthcare should never be one-size-fits-all, Daye champions health on your terms, combining convenience, quality and privacy through both physical products and a supportive digital platform. Transparency sits at the heart of the brand, with open access to research, supply chains and scientific insights so customers can make informed decisions. With a holistic approach to sustainability and a mission to close the gender health gap, Daye is redefining what equitable, evidence-led gynae care should look like.
