Protecting your privacy is the least we can do

Think of it as the immune system to your reproductive tract. It contains good bacteria (lactobacilli) and disruptive microorganisms (yeasts, viruses). A healthy vaginal microbiome is one where the good bacteria keep the disruptive ones in check, preventing them from growing out of control and causing an infection. A balanced microbiome has been linked to a lower risk of vaginal infections, STIs, and reproductive difficulties. Understanding your vaginal microbiome composition can help you better manage your gynaecological health.

The tampon offers a non-invasive, familiar method of obtaining a testing sample that makes the screening experience at home more comfortable and accessible. Further, tampons collect a comprehensive sample from the entirety of the vaginal canal, allowing for greater accuracy compared to traditional methods like swabs. The applicator enables smooth insertion in the vagina, and it also prevents the tampon from being contaminated during insertion.

There are several studies that show the correlation between having a healthy vaginal microbiome and a lower risk of getting vaginal infections like thrush and BV, a lower risk of contracting STIs, improved fertility and lower risks of miscarriage and pre-term birth, and a lower risk of developing gynaecological cancers. You can find more study references at the bottom of the vaginal microbiome screening page, as well as in your test results.

You should always speak with your physician before committing to purchasing a diagnostic test. However, not all physicians are experts in the vaginal microbiome or have time to keep on top of the latest research (for example, did you know that Bacterial Vaginosis was only recognised as an STI in 2021?)

The Daye screen uses novel, PCR-based technologies, and the interpretation of our data are informed by modern clinical studies, which can give you additional, richer insights into what's happening with your gynaecological health. Keep in mind it can take a while (usually 10-15 years) for new research to be put into medical practice, so don’t be surprised if your doctor hasn’t heard of the vaginal microbiome yet.

Don’t let that stop you from taking charge of your health, especially if you’re experiencing recurrent infections or trying to conceive. Recent studies (we have linked some of them at the bottom of this page) have shown just how important the microbiome is for vaginal, sexual, and reproductive health.

We will analyse your microbiome for lactobacilli (the good, protective bacteria), Gardnerella vaginalis and Prevotella (anaerobic bacteria, linked to bacterial vaginosis), Candida (a yeast linked to thrush), Mycoplasma hominis, Mycoplasma genitalium and Ureaplasma parvum and urealyticum, commonly linked to reproductive difficulties and vaginal infections.

When you use the Daye Diagnostic Tampon, your sample is analysed in accredited clinical laboratories, and the results you receive will cover high-risk HPV strains, common STIs ( Chlamydia, Trichomoniasis and Gonorrhoea), and vaginal infections like Bacterial Vaginosis, Thrush, Ureaplasma and Mycoplasma.

Our reports tell you exactly which pathogens were detected, using validated qPCR assays and ISO-accredited laboratory processes.

These results meet clinical standards and can be used directly for treatment, referral, or follow-up with your GP, sexual health clinic, or gynaecologist.

If your results show something that needs attention, we’ll explain what it means and guide you through the next steps so you can access the right care quickly.

After your sample reaches our lab, it will be analysed within 5–10 days. You will receive an email notification when your results are ready for review, or if there was an issue with your sample.

After you receive your results, you will be able to book a consultation with a vetted specialist and order medication (subject to additional costs and availability). We also help you make lifestyle changes to improve your gynaecological health. Did you know that everything from your contraception and condoms to underwear materials, can impact the composition of good and bad bacteria in your vagina? Stay in the know with Daye's screen and invest in interventions that actually work.

Our test uses quantitative PCR technology, which is able to quantify the relative amounts of microorganisms in your microbiome. While most GP/GU clinics use a method called microscopy to evaluate samples for pathogens causing BV or thrush, this requires a skilled technician to identify the presence of specific bacteria and differentiate them from one another. Microscopy is hence more subjective than DNA-based methods (like PCR) which detect the DNA of all microorganisms found in the sample in an automated way. Studies have shown that PCR is a more accurate way of assessing the bacterial composition of the vaginal canal than microscopy.

In practice, the PCR-based Daye screening results can point out if Gardnerella vaginalis (a common cause of BV) makes up 1% or 40% of a microbiome. Their amount is important because even though these bacteria are commonly found in a healthy microbiome, they can cause inflammation if they grow excessively.

We use certified labs in both the UK and US to test samples and process your results. Our UK partner labs are UKAS and CQC certified, while our US labs are CLIA and CAP certified. We also use CE-marked PCR panels. These certifications ensure our testing meets high quality standards.

In order to take a sample at least 5 days must have passed since your last period ended. There are a few other requirements: no antibiotics or antifungals in the last 30 days, no douching, penetrative vaginal sex, and vaginally applied meds or creams in the 24 hours before. That will ensure your microbiome is in a stable state and that your results are not inconclusive.

Using the kit at home is super easy — you just need to insert the provided tampon, wear it for at least 20 minutes (and up to 8 hours), and then put it in the pouches you have received in the kit, and ship it back to us in the same box you received initially. We’ve prepared detailed video instructions which you’ll see after completing the test activation questionnaire in your account.

• 2 tampons to take your sample — one to take your sample with and one for backup (double check the expiry date)
• A blue sterile pouch to keep the tampon sample safe from contamination
• A see-through shock-proof pouch to ensure the sample is protected on its way to the lab
• A 10 ml container with a transport medium liquid to protect your sample while on its way to the lab
• Step-by-step instructions on how to do the test + a card with the activation code
• For your convenience, the return label, which you can use to ship your sample back to our partner lab, is already attached to the outside of the box.
  Don’t use the kit if any of these is missing or damaged. Get in touch with our customer care team and we’ll sort it out.

At Daye, we believe in building products that are rooted in scientific rigour. This means that we never want to get ahead of the science available. Like many other areas of gynaecological health, vaginal microbiome research has been underfunded for decades.

Vaginal microbiome screening is also not a common practice in clinical care today unless you go private.

A vaginal microbiome screen is used to understand the composition of bacteria in your vaginal microbiome. This can help you identify the presence of pathogens, which could be causing you recurrent vaginal infections (Candida, Gardnerella) or preventing you from becoming pregnant (Ureaplasma, Mycoplasma). If you're peri-menopausal or menopausal, you may want to increase your lactobacilli count so as to fight off vaginal dryness. If you have suffered recurrent UTIs, you may find a disrupted vaginal microbiome to be the cause. Knowing that you have a low lactobacilli count can also help you and your physician make informed decisions on your risk of a recurrent miscarriage or pre-term labour.

Not every physician, however, will recommend a vaginal microbiome screen, due to the method not being widespread yet. Please feel free to consult with your doctor before purchasing this test. If you require a simple bacterial vaginosis or candida test, you can get one for free from your local sexual health clinic.

It's also important to note that by testing your vaginal microbiome you are contributing to an increased global understanding of the best ways to detect and manage gynaecological health diseases, in turn bridging the gender gap in medical research and innovation.

Tampons can potentially stretch or tear the hymen, but it's not a guaranteed or common occurrence. The hymen is a thin membrane that partially covers the opening of the vagina in some individuals. It can vary in thickness and elasticity from person to person. When inserting a tampon, if done carefully and gently, it typically shouldn't cause  damage to the hymen. However, if a person's hymen is particularly thin or if they have a medical condition called imperforate hymen (where the hymen completely covers the vaginal opening), there is a slightly higher chance of the tampon causing some stretching or tearing.

It's important to note that the hymen can naturally stretch or tear over time due to various activities such as physical activity, horseback riding, gymnastics, or even normal vaginal development. Sexual activity can also impact the hymen, but it's not the only factor in hymen integrity. In many cultures, there is a misconception that an intact hymen is a sign of virginity, but this is not a reliable indicator. Hymens can vary greatly in appearance and resilience, and not all individuals with intact hymens have never engaged in sexual activity.

We recommend avoiding the use of the tampon for vaginal diagnostics for a period of six weeks following vaginal birth. This allows ample time for the body to heal and reduces the risk of potential complications. Please consult with your healthcare provider for guidance specific to your individual situation.

In addition to the postpartum period, we advise against using the tampon for vaginal diagnostics if you have any open wounds, sores, or other vaginal irritations. It is essential to prioritize your comfort and well-being, and if you have any concerns, please consult your healthcare provider.

If you experience any discomfort, unusual symptoms, or adverse reactions while using the tampon for vaginal diagnostics, we recommend removing it immediately and consulting with your healthcare provider. Your health and safety are our utmost priority, and it is essential to address any concerns promptly.

Our Vaginal Microbiome Screening specifically detects the relative abundance of Lactobacilli and Anaerobic bacteria as a percentage of all bacteria in the sample. Very high levels of Lactobacilli (>80% of all bacteria) are generally associated with a healthy microbiome. Increased levels of anaerobic bacteria, such as Gardnerella, Porphyromonas and Prevotella spp. may suggest a higher risk of bacterial vaginosis (BV). While our screening offers valuable information, it is essential to remember that these results are not diagnostic on their own. To gain a comprehensive understanding of your vaginal health, it's important to discuss your results alongside your medical history and any symptoms you may be experiencing with a healthcare professional. Once you receive your screening report from Daye, you will be able connect with vetted specialists online.

While our nurses and vetted specialists can provide valuable insights and guidance, they can't formally diagnose conditions through Daye's platform. Our service is designed to help detect potential issues, but it's not a substitute for an in-person medical diagnosis.

However, we do offer a convenient pharmacy service. We partner with licensed prescribing pharmacists who can review your medical history and screening results. If appropriate, they can provide prescriptions for certain conditions like bacterial vaginosis or thrush, which can then be delivered discreetly to your door. This service offers a convenient way to access treatment for common gynaecological issues. For more complex concerns or if you're unsure, we still recommend following up with a healthcare provider for a comprehensive evaluation. Remember, your health and wellbeing are our top priority, and we're here to empower you with knowledge, resources, and convenient care options when possible.

Our diagnostic tampon screening service is only available to people aged 18 and over. This age requirement is in place due to regulatory reasons and because our service is designed for adults who can legally consent to medical screening and handling of sensitive health data without parental permission. The 18+ requirement ensures we're operating within legal and ethical guidelines for healthcare services.

If you're under 18, we recommend visiting your GP or a local sexual health clinic where appropriate services for young people are available. Many sexual health clinics offer free and confidential services specifically designed for teenagers.
