Why Take A Baseline Plus Test?

 Baseline Plus is our most comprehensive health check and is designed for those who want to improve and optimise their health. You’ll gain scientific results for 22 of your body’s most essential biomarkers for good health including; key micronutrients (vitamin D, B12, ferritin, folate), good & bad cholesterol, average blood sugar levels, inflammation, liver function as well as stress.

The data you’ll gain together with advice from our health experts, will identify whether you need to improve your diet, increase your exercise or reduce the stress load on your body. By gathering data over time you can build a picture of your own unique biomarker profile, discover what lifestyle changes work best for your body and get an early warning when things start to go wrong. 

When to take This test

It is recommended you collect your sample for this test within 3 hours of waking and before food.

Diet and Energy

Measuring your levels of active B12, ferritin and vitamin D will help you understand whether your diet is providing you with the right nutrients. Low levels of active B12, ferritin and vitamin D can contribute to low energy levels and feelings of fatigue. Vitamin D is also key for muscle function, bone health and a healthy immune system. The test also measures the thyroid stimulating hormone (TSH) which can indicate a thyroid imbalance – the symptoms of which include changes in weight, mood and energy.

Lifestyle Risk Assessment

It is important to track your risk of developing heart disease, liver disease or type 2 diabetes as these are all, on the whole, preventable illnesses. The Baseline Plus test gives you a breakdown of your different types of cholesterol levels (both good and bad), HbA1C which gives you a measure of how much sugar is in your diet and helps identify your risk for type 2 diabetes, together with key biomarkers to assess the performance of your liver.

Sleep and Stress

Sleep is crucial for your overall wellbeing.  Getting a good 7-8 hours sleep a night helps your mind and body repair and improves your immune system. Stress from our daily lives can impact our ability to sleep and stress also takes its toll on both the mind & body. Our Baseline Plus test measures your levels of the stress hormone cortisol so you can see what impact your lifestyle is having on your body.

What’s the Difference Between the Baseline and Baseline Plus Tests?

The major difference between the Baseline and Baseline Plus tests are the number of biomarkers they measure. The baseline test measures 16 key biomarkers associated with energy, liver function and cholesterol. The Baseline Plus test measures 22 biomarkers – the 4 additional markers are calcium, cortisol, hba1c and hs-CRP.

How Will My Lifestyle Affect
My Results?


Having a good, balanced diet is the most important part of staying healthy along with getting enough good quality sleep each night. This will ensure your body is getting the right nutrients to function well, and you have enough energy to exercise.

A poor diet that is high in fat, sugar and salt will impact your heart health and will not provide your body with the essential nutrients it needs to function well. High blood glucose levels can also cause inflammation in your body which is a risk factor for heart disease. High blood glucose also raises your cortisol levels.

Alcohol and Caffeine

We all know that drinking too much alcohol can affect our livers, but it also impacts our mental health by interfering with chemicals in our brain and our bodies ability to absorb nutrients.

Drinking too much caffeine can also have a negative impact on our bodies, such as increasing our cortisol levels.


Exercising and not taking in the right amount of nutrients and calories will put stress on our bodies and impact energy levels as well as our immune system. Mid to high intensity exercise can also increase cortisol levels, so you need to ensure sufficient rest periods between training sessions.

It’s also important to ensure your exercise routine is made up of weight bearing exercise to help with bone and muscle strength. Plus, exercise that increases your heart rate and makes you feel out of breath which will keep your heart and lungs healthy.


Having a stressful lifestyle can have a big impact on our bodies. Raised cortisol levels can contribute to weight gain, low mood, reduced libido and high blood pressure. Exercise and lifestyle changes will help reduce stress levels and improve overall wellbeing.

Frequently asked questions

Take the guess work out of your health. Here are some of the most frequently asked questions we get asked. If you need anything else try our help section.

  • How does the subscription work?

    When you purchase this product you will be given the option to sign up to a subscription every 3, 4, 6 or 12 months. Your next test will then be sent out automatically and your payment card will be billed. You can manage your subscription through your own personal dashboard where you view your results. You can change the frequency or cancel the subscription at any time.

  • Can I cancel my subscription?

    Yes, you can cancel at any time by logging into your own personal dashboard and clicking the cancel button. It’s quick and easy.

  • Should I take supplements?

    If your nutrient levels are outside of the normal range, then one of our doctors may suggest you take a supplement. For example, most adults in the UK need to take a vitamin D supplement, particularly during winter. However, you should be able to get all the nutrients you need by adjusting your diet. If you are already taking supplements, then the test will indicate if you should reduce or increase your dose.

  • What are the benefits of subscription?

    Sometimes life is just so busy you forget things that are important. Our Baseline Plus test is a tracking package designed to help you keep track of your health and see if the changes you are making are having an impact. The benefit of a subscription is that you can set the frequency of the repeat tests to suit your needs and you can start to build up a scientific blueprint of your unique biological health. Your dashboard will show a count down of the days until your next test, so you are always in control and we’ll send you a message just before your test kit is despatched.

  • Will I get advice if my levels are outside of the normal range?

    Yes. Our GPs will comment on any results that are outside of the normal range and offer advice on how to improve your results. The comments will be on your dashboard along with your results.
