Frequently asked questions​

This is what our customers ask us most about this test. For more information, try our help centre.

  • What does the liver do?

    The liver is a very important organ as it filters all of our blood, filtering out poisonous substances like drugs and alcohol. It also produces bile which is integral to digestion.

  • What are the first signs of liver disease?

    The signs of liver disease can include:

    • loss of appetite
    • feeling tired and weak
    • loss of libido
    • yellow skin and white of the eyes (jaundice)
    • feeling nauseous
    • feeling itchy

  • How can I keep my liver healthy?

    Remember that your liver has to work hard to filter out harmful substances in your blood, what you eat and drink has an important part to play in ensuring a health liver.

    The following can help to ensure a healthy liver:

    • moderate the amount of alcohol you drink (NHS alcohol support)
    • drinking a few cups of coffee may reduce cirrhosis (scarring) of the liver
    • practise safe sex to avoid hepatitis C, which infects the liver
    • monitor the use of prescription drugs that may harm your liver
    • be careful what supplements you take as your liver can be harmed by: coltsfoot, comfrey, groomwell, and borage
    • eat a wide range of fruits and vegetables as part of a balanced diet low in ultra-processed foods
    • exercise and keep a healthy BMI
    • monitor your liver function with blood tests

  • 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 first class post, so it should be with you within 1-2 working days.

  • How secure is my data?

  • 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.

Recommended by doctors

"Your liver is the body's major processing centre. A liver function test measures various enzymes, proteins, and substances in your blood that are involved in a number of metabolic pathways. The results show if your liver is functioning properly, helping assess the impact of diet, alcohol, exercise and some medications."

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.
