How soon will the test arrive?

If you order your test before midday on a Monday to Friday then your kit will be dispatched the same day. All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2 working days.

Do I have to take the test during the same menstrual cycle?

Yes. Both blood samples must be taken on day 14 and day 21 of the same menstrual cycle.

What days do I need to take the test?

You will need to take a finger prick blood sample on day 14 and day 21 of the same menstrual cycle.

What should I do if my day 14 or 21 falls on a Fri through Sun?

If your day 14 or 21 falls on a Friday, we recommend you collect your sample the day before. If your day 14 or 21 falls over the weekend, collect your sample on the following Monday and remember to post in a priority post box in time for that day’s collection.

Should I change the test days if I have a longer or shorter cycle?

No, our algorithm will adjust your curves to the length of your personal cycle, so it is important that you collect your samples as close to day 14 and 21 as possible, even if you have a longer or shorter than average cycle.

When will I get my results?

MyFORM® test is a double test kit which measures your fertility hormones at two points within the same cycle – day 14 and day 21. Once our lab has completed the analysis of both samples, you’ll receive your personalised report via your secure dashboard.

How do I find out my results are ready?

We keep you updated throughout the process by email and text message. We will let you know when your blood sample has arrived at our lab. Once the blood sample has been analysed one of our doctors will review your results. Once your results are ready, we will email you and send you a text message to let you know your results are ready for you to view in your health dashboard.

How do I view my results?

When you buy your test, we will ask you to create an account with us during checkout. This will give you access to your own, secure health dashboard where you can view your results.

Why is MyFORM® revolutionary for women?

By combining scientific blood analysis taken on day 14 and 21 of your cycle and information about your unique cycle length, MyFORM® uses AI to mathematically map how each of the 4 key hormones that change during perimenopause fluctuate across your entire cycle not just on a single day.

What will the report tell me?

Your report will indicate if your symptoms are likely to be due to perimenopause. You’ll get a detailed, personalised report with next step actions from an endocrinology expert. The report will tell you: If your symptoms are likely due to perimenopause Graphs indicating how each hormone fluctuates across your unique cycle Your FORM – ovarian response – score indicating how well your ovaries are responding to your control hormones – an indicator of perimenopause Personalised ranges for each of the 4 hormones tested on day 14 and day 21 Confirmation if ovulation has occurred Clear next steps and actionable advice

What is the FORM score?

The Forth Ovarian Response Metric (FORM) is a unique and innovative evaluation of the functioning of the hormone network. This score takes into account all your hormone results rather than looking at anyone in isolation. A score above 75 suggests a healthy ovarian response. Women over 40 can expect to see a decline in their ovarian response score as they enter the perimenopause and approach the menopause.

Why can’t I take this test if I’m taking a hormonal contraception or HRT?

Any hormonal contraception or HRT will mask your natural hormone levels. This product has been specifically designed for those who have naturally occurring cycles. If you are using a copper coil you are able to take this test.

Can I take the results to my GP?

Yes, you can download your results from your health dashboard as a PDF to share with your GP.

Why do the MyFORM® test?

Periods are a sign of a healthy hormone network, yet training overload, poor recovery and under fuelling can cause your periods to become irregular or stop altogether – a condition known as RED-S. MyFORM® will give you detailed insight into your hormone network to ensure you’re training, resting and fuelling correctly.

We’re changing people’s lives

I really like Forth and you probably saved my life because your lab discovered my critically low cortisol which was subsequently diagnosed as adrenal insufficiency by a hospital endocrinologist.

Maria

I find Forth professional and forward-thinking with a bigger range of tests than more traditional healthcare providers in the UK. I think it is closer to what you can get from US providers.

Richard C

I wanted to get more information about my own health instead of using the NHS who just test for a specific reason. I also wanted better historical data to view changes over time as the NHS systems aren’t very good for that.

James W

Finding out what is going on inside your body is key, especially now that the NHS is in crisis. If we can take control of our wellness (and flag up potential problems early) that has got to be a good thing.

Vannesa C

I am very satisfied with your excellent service and I have recommended you to all my friends who are also very interested in your products.
