As you lose weight, various internal health markers adjust. This test gives you a clear insight into these shifts, allowing you to tailor your approach with comprehensive knowledge. This ensures your weight loss isn't just about appearance but about enhancing overall health, reducing the risk of diseases, and potentially increasing longevity.
We recommend taking the Weight Loss Blood Test at the onset of your weight loss journey and then monitoring your progress. This will help you to align with your goals and keep you motivated to improve your health.
Each blood test is easy to use, even if you’ve never used a home blood test kit before.
It only takes a small amount of preparation to successfully collect a blood sample and all the equipment you need to do so is included in the kit.
A summary of how to use the tests:
Wash your hands in warm water for 4 minutes and then dry them.
Use the lancet provided to prick your finger and collect a blood sample.
Post your sample to our accredited partner laboratory using the prepaid envelope included with your test.
Full instructions are provided with your test, which you should read thoroughly before use to ensure the best results.

Yes. It’s designed to be taken at home and we’ve included detailed instructions to help you through the process. We’ll also break down your results into simple, easy-to-understand language, so you’ll learn where you stand and how you can improve your heart health.
You should receive your blood test results three to five working days after you post your blood samples.
You’ll get an email notifying you that your results have arrived in your Numan account, so keep an eye on your inbox so you don’t miss them. Additionally, you’ll receive a written review of your results from one of our clinicians, which you can read alongside your results to help you understand them.
Once they’re in your account, you can view your results any time you wish. You can also view them in-app and save your results as a PDF to help you keep track of them (and show them to your GP if need be).
Small changes to your biomarkers are normal and generally nothing to worry about. However, any significant changes in your health markers should prompt a discussion with a healthcare professional. They can provide context, possible explanations, and guidance.
While weight loss often influences these markers, everybody and every body is different. That's why it’s a good idea to keep track throughout your journey.
The Weight Loss Blood Test can only indicate rather than diagnose health issues. If you’re worried and suspect you might have an underlying health condition, we advise speaking to your regular doctor first. If you get any unexpected or unusual test results, this should also be flagged and discussed in more detail with your doctor.
Unlike generic blood tests, this test specifically focuses on biomarkers that are crucial in understanding the internal shifts driven by weight loss. It’s tailor-made to give you insights related to cardiovascular health, diabetes risk, and other vital parameters associated with weight reduction and overall health.
