Order and book your onboarding call, complete your symptom assessment, collect your sample at home and post it the same day. Your report is ready within 2–3 working days of the lab receiving it, then you talk it through with your clinician.
Collect your sample on days 1–5 of your cycle. If you don’t have a regular cycle, you can collect on any day.
Anyone with irregular or missed periods, adult acne, unwanted hair growth, hair thinning or unexplained weight changes who wants to know whether PMOS (previously PCOS) could be the reason.
Your report is ready within 2–3 working days of the lab receiving your sample, in your secure portal.
Here's the honest truth: HRT and hormonal contraception are designed to change your hormone levels, so your test results won't reflect what's naturally happening in your body.
Here's what gets affected:
FSH, LH, Estradiol: These often get suppressed or altered because your body thinks it doesn't need to produce them naturally
Prolactin: Usually stays put – this one's pretty resilient
Testosterone: Birth control often increases SHBG (the protein that binds testosterone), so you might see lower readings
TSH, T4: Your thyroid usually carries on as normal
Ferritin, Vitamin D: These don't really care what hormones you're taking
If you're on these treatments, your results will be like trying to understand your natural sleep pattern while drinking coffee all day – not impossible to interpret, but definitely trickier. That's why we don't recommend testing while you're on hormonal contraception or HRT.

Your data is for your eyes only
Protecting your privacy is the least we can do
Your data is pseudonymised, encrypted and stored to ISO 27001 standards. We never share your results without your explicit consent: not with your insurer, your employer or advertisers.
Before you begin, you’ll have a free 10-minute call with one of Daye’s nurses. They’ll walk you through the assessment process, explain when to take the hormone test in your cycle, and answer any questions. It’s designed to make you feel confident and ready – so nothing feels like a surprise once your kit arrives.
It's more than a simple screening flag. A nurse reviews your hormone data and symptom profile against the NICE, RCOG and ESHRE criteria, and talks it through with you during your consultation, so you leave with a clear picture and a plan.
Most GPs welcome a structured letter from a registered clinician with a full hormone panel, from an accredited lab, attached, because it saves them the workup. Your GP makes their own clinical judgement and may want to repeat or add tests. What the letter does is start the conversation at the point you'd otherwise reach months to years from now.
Yes. The Daye Hormone Test device collects a clinical-grade sample from your upper arm, which is then analysed in a UKAS-accredited, CQC-regulated lab.Most people describe it as painless.
Days 1-5 of your cycle, counting from the first day of proper bleeding. If your cycle is irregular or absent, any day works.
That's still useful not a wasted £239. It narrows down the most likely explanation and points at what to look at next. Thyroid dysfunction and high prolactin all produce similar symptoms, and are all tested for in your included panel. Your letter will say what the findings suggest and your clinician will advise you on your next steps.
Your signed GP letter follows the call. If your results are consistent with PMOS, you also get a care plan for where you are now. If the picture needs further investigation, your clinician tells you exactly what and why, and it goes in your letter.

We don't recommend hormone testing during pregnancy or while breastfeeding, as hormone levels during these periods will not reflect your natural baseline. The symptom questionnaire can still be completed.
Hormonal contraception and HRT affect your natural hormone levels, which means results won't reflect your baseline. We recommend a washout period of 6–8 weeks before testing. The symptom assessment can be completed at any time.
PMOS (Polyendocrine Metabolic Ovarian Syndrome) is the new name for what was previously called PCOS (Polycystic Ovary Syndrome). In May 2026, The Lancet published a global consensus renaming the condition to better reflect its true nature: a complex hormonal and metabolic syndrome affecting multiple body systems, not just the ovaries. The condition itself hasn't changed - the understanding of it has. If you've previously been told you might have PCOS, or if you're still looking for answers for PCOS, this assessment is for you.
Signals your ovaries to release an egg. A raised LH-to-FSH ratio is often seen in PMOS.

Ferritin is a protein that stores iron in the body and releases it when needed. It helps regulate iron levels and is commonly used to measure iron deficiency or overload.
