Published research

Efficacy and acceptability of a self-collected medical grade tampon as a novel vaginal sample collection tool for the detection of HPV and STIs

This study aims to compare the efficacy and suitability of a self-collected tampon for the detection of human papillomavirus (HPV) and sexually transmitted infections (STIs) using qualitative TMA-based assays

Can samples taken with Daye tampons be used after being freezed?

There’s no statistically significant difference between corresponding fresh and frozen samples, enabling the conclusion that samples can be frozen before processing. The ability to freeze tampon samples allows for processing at a more practical time.

Menstrual Tampons Are Reliable and Acceptable Tools to Self-Collect Vaginal Microbiome Samples

Menstrual tampons are a more effective tool for sample collection compared to the vaginal and cervical swabs. There are confirmed similar results in literature with reports of high specificity with variable sensitivity.
