If you purchased multiple test kits for your household, some special notes:

Each test kit can only have one unique email address associated with it when registering. Everybody in your household will need to have a separate and unique email address to register their test kit.

Make sure that the test kits are identified for each individual after online registration is complete. This is important because the sample collection tubes are associated with the Sample ID. We recommend writing down each person's name on the outside of each test kit to avoid mixing up test kits, sample collection tubes, and ensure the Sample ID matches the registered email address.

Please note that you will not be able to switch test kits with someone else after registering a test kit. Healf Zone requests separate and unique email addresses to create an account for each household member to prevent confusion on which test results belong to which household member.

If you believe that you need to change the biological sex, date of birth, or e-mail address information stored on your account, please contact our customer service team here.

Currently, we are unable to offer the option to order our blood tests outside of the UK. However, we are working towards expanding Healf Zone to enable customers to upload their own test results in the future. We appreciate your understanding and look forward to providing this valuable feature soon.

In the meantime, you can sign up on our mailing list and when our service outside of the UK is up and running we will contact you.

You will need to fast for 8 hours before collecting your sample. For the best results, we recommend completing the test in the morning and drinking at least two glasses of water 30 minutes before you begin.

You should collect your sample in the morning after an 8-hour fast any day between Monday - Thursday, as this ensures your test arrives at the labs on a working day. Please avoid Fridays, Saturdays, and Sundays, as your kit may sit in transit too long, which could result in a failed test. Your collected sample should then be posted the same day to prevent the sample from coagulating, which then cannot be used by the lab.

• Our number one tip is to follow the instructions closely and carefully while making sure to take your time collecting your sample. Our instructions and tips are there for a reason (we promise!) and by following them you have the best chance of collecting your sample in the best way to get accurate results.

- Stay hydrated:  Drinking plenty of water before your test allows blood to flow more freely.

- Exercise:  Exercise can help increase blood flow - we recommend some light exercise like swinging arms or some star jumps should be sufficient.

- Warm up your hands:  Place your hand in warm water for 3 minutes, or take a hot shower before taking the test. 

- Massage your finger: When you’ve pricked your finger, massage it to stimulate blood flow in a milking motion down to the pricked area. Don’t squeeze your finger tightly, as this can affect the plasma dilution and lead to haemolysis. If you feel like you can’t get any more blood from your finger, clean another finger and use a new lancet to try again.

- Stand up: Gravity can help with blood flow, so consider standing during the collection process. You could also make sure that your hand is hanging down, and drip the blood into the tubes that way.

- 8-hour fasting: Fasting for about 8 hours before the blood draw will help ensure the accuracy of the blood test. The easy way to do this is to take your test before you’ve had breakfast, after waking up.

- Mix tubes correctly:  After you've collected your blood, it's crucial to mix it properly with the additives in the collection tube. Follow the instructions provided on how to do this, and you’ll be mixing like a scientist.

- Collect samples Monday to Thursday:  This ensures that your sample isn't sitting in a postbox or sorting office over the weekend, or at our lab, which could lead to sample degradation.

- Post your sample promptly:  Post your sample the same day you collect it, in a priority postbox – you can find one here: https://www.royalmail.com/services-near-you#/. Delaying sending your sample can increase the risk of haemolysis.

While we’ll try our best to help find a solution, at-home blood testing may not be for you right now. We want to make sure that everyone has access to their health data. So, the good news is that we’ll soon be introducing a phlebotomy service. This means you’ll be able to visit a participating nearby pharmacy or health clinic and have your blood drawn for you venously, which you can then send to our lab for results.

Your sample will be sent to and analysed at Alderly Lighthouse Labs, our trusted partner for delivering accurate and reliable results. We’ve chosen them to ensure your test is handled with care and precision every step of the way.

Once we receive each set of results, we will notify you through email and text. You can access the results directly by logging into Healf Zone.

After receiving your test results, you will enjoy a one-on-one consultation with one of our experts to discuss your results in depth and focus on what matters most to you. Healf Zone provides access to specialist tests for areas such as metabolic health, fertility, sleep, and more, ensuring a comprehensive understanding of your wellbeing. This consultation is included with your Healf Zone package at no extra cost.

No, Healf Zone does not replace your doctor or concierge care. Instead, it makes you a more powerful patient. Healf Zone empowers you with knowledge of your key health biomarkers and provides detailed insights from functional medicine experts, specific to your results. Additionally, you will receive a supplement plan to optimise your wellbeing and a dashboard to track your progress.

Bringing a history of lab test results to your next doctor visit may reduce the need for follow-up tests and enable a more productive appointment. Healf Zone is designed to make the doctor's time more effective and empower you to be your own advocate.

Your body is ever-changing. Your eating, sleeping, stress and outdoor exposure all impact your body. Regular testing allows you to understand how your health is changing and therefore what you can do to improve it.

Healf Zone includes insights that can help illuminate the role of vitamins, minerals, and toxins on your wellbeing and the imbalances that can sometimes contribute to depression, anxiety, brain fog, insomnia, attention deficits, mood swings, and more.

While we aim to provide a full set of biomarker results, occasionally, some biomarkers may be missing. This is typically due to factors like insufficient sample volume or contamination, rather than being indicative of your wellbeing. 

If your panel still provides a comprehensive overview of your health, you’ll have full access to your Healf Zone results and receive a gift card reflecting the number of missing biomarkers. 

If the results are insufficient for a detailed analysis, no need to worry. You’ll have the opportunity to take another test free of charge, along with a complimentary consultation with one of our experts to guide you through the process. This is our way of supporting you as you continue your journey to unlock your optimal wellbeing.

Yes, medications can impact the results of a blood test. Certain medications may affect the levels of various biomarkers in your blood, potentially altering the test outcomes. The health assessment that you do will also ask you what medications you are taking so that we are aware and any medications you take are recorded on your dashboard.

If you have any concerns about specific medications and their impact on your blood test, we recommend consulting with your healthcare provider once receiving your results.

We understand how important accurate health data is – it’s our whole business. That's why we offer free, express returns to get your sample to our lab as soon as possible. Our labs are fully safety accredited with our test kits regulated by the Medicines & Healthcare Products Regulatory Agency, and we’re continuously improving our methods to get you the most accurate results possible.
