Blood sample collection options
You can choose your preferred collection method when you checkout
Finger prick kit (FREE)
You can do this test at home without the need for a doctor. We'll send you everything you need to collect your sample and post it back to us. And it's all included in the cost. We've put together a video that covers the process, making it easy to check and track your health from home.
Home nurse appointment (+£60)
We'll arrange for a medical professional to visit your home and collect your sample. This is great if you're unsure on how it all works or have trouble collecting a sample. No need to book a doctor's appointment or visit a clinic, we'll send you everything you need to collect a sample and post it back to our labs.
Visit a partner clinic (+£45)
Once you've ordered your test, look out for an email from our phlebotomy partners containing information and a link to book your appointment. We'll send you everything the clinic will need to complete the sample and post it back to our labs.
Organise a nurse myself (FREE)
If none of the above options work for you, you can arrange your own medical professional to collect your sample. There is no additional charge for this. Once you've ordered your test, we'll send you everything you and your chosen medical professional will need to collect a sample and post it back to our labs.
Still unsure how it works? You can find more information on collection methods and the service we provide in our 'How it Works' section.

What are biomarkers?
Biomarkers are specific compounds we can detect in your blood sample that reflect different things about your health. Your test will tell you your levels for each of the above biomarkers, and whether they are in a normal range.
About flexible subscriptions
How does a subscription work?
When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.
When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).
Why subscribe to multiple tests?
One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.
How often should I test?
We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!
Can I change what's tested in future tests?
Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

WHEN TO TAKE THE TEST?
If you're having a period this test should be taken on day 3 of your menstrual cycle (day 1 being the first day of your period). If you're not having a period, it can be taken at any time.
IMPORTANT: If you're using a hormone gel or cream, we would highly recommend the sample is collected via a phlebotomy draw (blood drawn via a vein) due to the risk of contamination.

Checking Your Oestradiol Levels at Home
Oestrogen plays a crucial role in regulating the menstrual cycle, supporting fertility, and maintaining bone, heart, and skin health. Imbalances can lead to symptoms like irregular periods, mood swings, low libido, and hot flushes, particularly in menopause.
Our Oestradiol Blood Test measures your oestradiol (oestrogen) levels with a quick and easy home blood test. Whether you’re experiencing hormonal symptoms, managing conditions like PCOS, or monitoring your hormone levels through perimenopause and menopause, this test provides essential insights.
Simply collect your sample using our finger-prick kit and send it to our accredited lab. Your results will be reviewed by a doctor and available in the Forth app, along with expert guidance on what your levels mean and how to improve your hormonal health.

2. View your results
You will receive your Results within 2 working days in the Forth app, along with the optional doctors comment and detailed report.
3. Make improvements
The detailed report makes it easy to identify areas that need improving, make changes and track your progress.
Oestradiol Blood Test, recommended by our doctors
"Oestrogen is the main ovarian hormone, this test offers a snapshot picture of your oestrogen levels. Although useful to monitor fertility, menopause, or hormonal imbalances it should be used as part of a wider panel to help understand your whole hormone network."

Frequently asked questions
This is what our customers ask us about the most. For more information, try our help centre.
What does this test measure?
This test measures oestradiol (the primary form of oestrogen in the body) to assess hormonal balance, reproductive function, and overall health.
Who should take this test?
It’s suitable for women over 18 years of age who want to track their oestrogen levels, including those experiencing irregular periods, menopause symptoms, fertility concerns, or conditions like PCOS.
How does oestrogen affect fertility?
Oestrogen regulates ovulation and prepares the uterus for pregnancy. Low levels can disrupt ovulation and make conception difficult, while high levels may indicate conditions like PCOS or oestrogen dominance.
Can this test confirm menopause?
This test alone cannot confirm menopause, but tracking oestrogen levels over time can indicate hormonal changes associated with perimenopause and menopause.
Our MyFORM Perimenopause Test uses 2 blood samples and groundbreaking AI to accurately measure and map your hormones across your menstrual cycle, giving you a better understand of perimenopause.
What are the symptoms of low oestrogen?
Symptoms include irregular or absent periods, vaginal dryness, low libido, mood swings, fatigue, and weakened bones.
What are the symptoms of high oestrogen?
High oestrogen can cause heavy or irregular periods, bloating, tender breasts, headaches, mood swings, and weight gain.
Can this test help with hormone replacement therapy (HRT) monitoring?
Yes, this test can help you track your oestrogen levels if you’re using HRT to manage menopause symptoms.
When should I take this test?
If you have regular periods, test on day 3 of your cycle for the most accurate readings. If you are postmenopausal or on HRT, you can test at any time.
How often should I test my oestrogen levels?
If you’re tracking changes, testing every 3–6 months can help you monitor hormonal fluctuations. Tracking your oestrogen along with other key female hormones can provide a more complete picture of your hormone changes. Our Female Hormone Blood Test can help with that.
How quickly will I receive my results?
Your results will be available in the Forth app within 2 working days of your sample reaching our lab.
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 Tracked24, so it should be with you within 1-2 working days.
How secure is my data?
We have strict processes in place to ensure the protection of your data. Following GDPR the company also operates under tight legal rules about the sharing of data which ensures that data is only shared if it is crucial to the delivery of our service. For example, our doctors see customer results at the time of review, however, after review, access to results is withdrawn.
Learn more about your data security.
Can I have someone take my blood for me?
Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.
A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.
The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
Does a doctor review my results?
We have a team of doctors and nurses who look at all results and will comment on any results that are outside of the normal range for your age.
Can I download the results to share with my GP?
Yes, you can download your results from your health dashboard as a PDF to share with your GP.
