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.

STEP 1

Make sure you meet all the requirements listed above.

STEP 2

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.

STEP 3

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.

STEP 4

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.

STEP 5

Wash and dry your hands.

STEP 6

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.

STEP 7

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 1 hour.

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

STEP 8

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

STEP 9

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

STEP 10

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.

STEP 11

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.

STEP 12

Place the tampon into the blue sterile pouch.

STEP 13

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

STEP 14

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

Rinse and dry the empty container prior to disposing it.

STEP 15

Hold the bag by the wire tab ends...

STEP 16

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

STEP 17

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

STEP 18

Place the blue pouch inside the larger see-through pouch included in the kit. Use the seal on the big pouch to close it up.

STEP 19

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

STEP 20

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

STEP 21

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.

STEP 22

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

Additional Information

Just like any other lab test, the information from the Daye Gynae Screen is not intended to diagnose, treat or cure any medical condition by itself.

This is why we make it easy for you to connect with vetted, empathetic medical specialists who will help you make sense of your results. If you have any questions about your results, or how to access aftercare, please reach out to hello@yourdaye.com

If you've ever used a tampon, then you've probably heard of toxic shock syndrome (TSS). TSS is a rare but serious and potentially life-threatening condition that all tampon users should be mindful of. The only way to completely prevent getting tampon-associated TSS is to not use tampons. Keeping your tampon in for more than 8 hours significantly increases your risk of TSS.This tampon is designed for sample collection and should be worn for no more than 1 hour. If you do experience any of the symptoms below, please remove your tampon immediately and seek the advice of a doctor. TSS can progress quickly, so it's important to let someone you trust know you may be experiencing TSS ASAP. People who've had TSS once can also get it again, whether they're using tampons or not (unfair, right?). If you've had TSS before, or have questions about TSS and using tampons in the future, get in touch with your doctor before starting to use tampons again.


Sudden high fever (above 39°C), flu-like symptoms such as headache, chills and muscle aches, a sore throat and cough, diarrhoea, a widespread and sunburn-like rash, the whites of the eyes, lips and tongue turning a bright red, dizziness or fainting, breathing difficulties, confusion and/or drowsiness. Our advice: Don't let a tampon overstay its welcome!


The transport medium liquid (TML) formulation includes proteins for virus stabilisation, antibiotics and antimycotics to prevent overgrowth of bacterial and fungal flora and a buffered solution to maintain a neutral pH (pH 7.3 ± 0.2 at 2÷25°C)


• Sucrose • HBSS solution • Bovine serum albumin • Buffered solution • Gelatin • Amino acids • Antibiotics • Phenol Red


All Daye tampons are manufactured at a facility compliant with medical device manufacturing standards, including ISO 13485 and GMP. Our testing kits are analysed by UKAS-accredited and CQC-registered partner laboratories. As with any diagnostic test, results should be interpreted by a qualified healthcare professional, taking into account the patient’s symptoms and medical history.

Any prescriptions or treatments offered via the Daye platform are issued by third-party, independent pharmacies regulated by the GPhC and CQC.
