Wait, the vaginal micro-what?
Like your gut, your vagina is home to billions of bacteria (some good, some bad). These make up your vaginal microbiome. When it doesn’t contain enough good bacteria, you’re at greater risk of vaginal dryness, fertility challenges, as well as infections like STIs, thrush and BV.
Which pathogens do we test for?
With cutting-edge PCR technology for unparalleled accuracy, Daye tampons collect more vaginal fluid than a standard swab and cover the whole vaginal canal.

Relevant Research
Diagnosis of bacterial vaginosis on self-collected vaginal tampon specimens
2002 • P D J Sturm, P Moodley, G Nzimande
Results of the tampon and vaginal smears showed excellent agreement for both observers (Spearman >0.80). The overall sensitivity and specificity were 91.7% (95% CI: 81.6-96.5) and 79.3% (95% CI: 67.2-87.8), respectively, using the Amsel criteria as reference standard. The tampon provides a specimen for the combined diagnosis of non-ulcerative STIs and BV.
A Self-Administered Technique for the Detection of Sexually Transmitted Diseases in Remote Communities
1997 • Sepehr N. Tabrizi, Barbara Paterson, Christopher K. Fairley, Francis J. Bowden, Suzanne M. Garland
The detection of each organism was significantly greater by PCR in tampon-collected samples than by routine conventional methods (P < .01).
Pilot study of the utility and acceptability of tampon sampling for the diagnosis of Neisseria gonorrhoeae and Chlamydia trachomatis infections by duplex realtime polymerase chain reaction in United Kingdom sex workers
2010 • P T Kimmitt, S N Tabrizi, M Crosatti, S M Garland Frcpa, P C Schober, K Rajakumar, C A Chapman
Besides near-universal acceptability of tampon sampling, the tampon sampling–PCR approach described in this study appeared to have enhanced sensitivity compared with conventional testing.
Vaginal microbiome and sexually transmitted infections: an epidemiologic perspective
2011 • Rebecca M. Brotman
Vaginal bacterial communities are thought to help prevent sexually transmitted infections. Bacterial vaginosis (BV) is a common clinical syndrome in which the protective lactic acid-producing bacteria (mainly species of the Lactobacillus genus) are supplanted by a diverse array of anaerobic bacteria. Epidemiologically, BV has been shown to be an independent risk factor for adverse outcomes including pre-term birth, development of pelvic inflammatory disease, and acquisition of sexually transmitted infections. Longitudinal studies of the vaginal microbiome using molecular techniques such as 16S ribosomal DNA analysis may lead to interventions that shift the vaginal microbiota toward more protective states.
The Vaginal Microenvironment: The Physiologic Role of Lactobacilli
2018 • Emmanuel Amabebe, Dilly O. C. Anumba
Lactobacilli and their antimicrobial and anti-inflammatory products along with components of the epithelial mucosal barrier provide an effective first-line defence against invading pathogens including bacterial vaginosis, aerobic vaginitis-associated bacteria, viruses, fungi and protozoa. An optimal host-microbial interaction is required for the maintenance of eubiosis and vaginal health.
The role of Escherichia coli in reproductive health
2017 • P Cools
Vaginal dysbiosis has been associated with increased susceptibility to and transmission of HIV and other sexually transmitted infections and increased risk of pelvic inflammatory disease, pre-term birth and maternal and neonatal infections.
