How to use the screening kit?

On this page you’ll find more information about your kit and detailed instructions how to use it to take your sample.

Before you start, make sure that:

You’re over 18 years old

Your last period ended at least 5 days ago

You haven't taken any antibiotics or antifungals in the past 30 days

You haven't had vaginal penetrative sex in the last 24 hours

You haven’t used any vaginally administered meds, creams, douches, gels, or similar in the past 24 hours

Get to know your kit

Make sure your kit has everything listed below before you start sampling:

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

In the case of damaged, or opened packaging, please refrain from using the kit. Simply get in touch with our customer care team to request a new one.

Important! Our tampons are applicator tampons— please do not remove the applicator before insertion! It’s very important that you don’t touch the actual tampon with your hands as our tampons are sanitised to ensure we get an accurate screening.

Detailed instructions

Follow these instructions carefully to make sure you get the most out of the screen. Don’t worry, the whole thing should take about 30 minutes.


Make sure you meet all the requirements listed above.


Before you take your sample, activate your test by completing the online questionnaire. This will help us contextualise your results and provide you with personalised health insights.


To ensure timely delivery to our lab, please collect your sample at least 5 days after your last menstrual cycle and send it for delivery to our lab on the same day.


Prepare the kit by laying it out on your bed or your bathroom counter. Don’t get rid of the box yet — you’ll need it later on.


Wash and dry your hands.


Unwrap your Daye tampon and insert it into your vagina. Make sure to push the tampon out of the applicator until you feel a bit of resistance against your cervix.

step 1step 2step 3step 4

If this is your first time using a tampon: lay down with your back on your bed, lift your legs up, spread your labia apart and insert the applicator into your vagina fully. Alternatively, pop one of your legs up on the toilet. Make sure to push the tampon out of the applicator until you feel a bit of resistance against your cervix. After the tampon has been inserted, wash the applicator with warm water and recycle as normal.


Keep the tampon in for at least 20 minutes. You can keep it in for longer if you’d like to, but no longer than 8 hours.

Tip: setting an alarm on your phone is a good idea if you’re worried you might leave it in for too long.


Just before you remove the tampon, tear off the top part of the blue sterile pouch along the perforated line.


Use the pull-tabs in the middle to pull open the bag.


Take your tampon out by gently pulling on the string. Avoid touching the tampon with your fingers (it’s okay to touch the string) or bumping the tampon into anything (like the toilet bowl), to avoid contaminating it.


Be careful with this step — contaminated tampons can make your test invalid or lead to incorrect results.

If your tampon sample contains menstrual blood or urine, or touches a non-sterile surface, chuck that one away, wait for 24 hours and repeat the steps above with the spare tampon in your kit.


Place the tampon into the blue sterile pouch.


Unscrew the cap of the container containing the transport medium liquid.


Carefully transfer the container's contents into the sterile pouch, ensuring no spills occur.

Rinse and dry the empty container prior to disposing it.


Hold the bag by the wire tab ends...


...and fold over 5 times to seal and make it air-tight.


Fold both wire ends over the bag to secure it in place.


Take the blue pouch with the tampon and place it inside the larger see-through pouch included in the kit. Use the seal on the see-through pouch to close it up.


To ship the sample, place the see-through pouch, containing the blue pouch with your sample, into the box.


Reseal the cardboard shipping box by removing the peel-off strip and firmly pressing the tape against the marked seal area.


Follow the shipping instructions provided at the end of the activation questionnaire to send back your sample for analysis.

Please make sure to send your kit on the same day after you have taken your sample to ensure quicker and more accurate results.


Voilà! We’ll send you an email when your results are ready to review.

Daye tampons are manufactured in accordance with medical device standards, including ISO13485 and GMP. In order for a diagnosis to be confirmed, test results from the Diagnostic Tampon should be considered by a licensed healthcare provider alongside a patient's symptoms and medical history. Like every other diagnostic test, lab results are not sufficient for a diagnosis. Daye offers customers the option to connect with independent CQC-regulated healthcare providers virtually and in-person for a confirmed diagnosis. All prescriptions and treatments provided through the Daye platform are issued by third-party, independent pharmacists, who are also regulated under CQC and GPhC.
