Why do the Advanced Energy test?

If you’re wanting a more comprehensive analysis to help identify the cause of low energy, then this test is for you. It checks key nutrients such as vitamin D, B12, folate and ferritin along with cortisol (stress), magnesium, and hs-CRP (inflammation). To rule out conditions that could be causing your symptoms this test also checks HbA1c (pre-diabetes) along with thyroid, liver and kidney function along with immune health.

  • How do I take my blood sample

    So, we’ve created a how-to video to help you collect a successful sample.

    But don’t worry if you don’t manage to get it right first time, just contact our customer support team at [email protected] to request a replacement kit.

  • 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.

"This test incorporates 24 markers that includes all the 'usual suspects' when we are looking to identify why someone is fatigued or not performing their best. Identifying nutritional deficiencies, hormonal imbalances and metabolic dysfunction means being able to take positive steps to address the root cause and boost your energy levels. "

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.

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 health markers 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.

Blood sample collection options

You can choose your preferred collection method when you checkout

  • Do it yourself options
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.

  • Have a nurse do it
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.
