Why Take A liver function test?

The biomarkers used in our liver test can indicate liver inflammation and help detect damage which may have arisen from a poor diet or high alcohol consumption.

If liver problems are spotted early you can make proactive lifestyle changes to improve your liver function health.

The biomarkers used in this test are alanine aminotransferase (ALT), albumin, alkaline phosphatase (ALP), bilirubin (total), gamma GT, globulin, and total protein.

Taking control of your health and gaining a deeper understanding of your liver health may help to identify potential problems early and keep your liver fit and healthy.

How To Improve Liver Health

A Healthy, Balanced Diet

Having a diet that is high in saturated fat and sugar can lead to non-alcoholic fatty liver disease which can cause inflammation.

A healthy, balanced diet will help to keep your liver healthy and should include the following:

  • Plenty of fresh fruit and vegetables
  • Whole grains, nuts, beans and lentils
  • Lean meats such as chicken and turkey
  • Oily fish such as salmon
  • Swap saturated fat for unsaturated fat
  • Reduce the amount of fatty meats you eat along with processed meat such as sausages and bacon
  • A small amount of high-fat dairy products
  • Low sugar intake
  • No more than 14 units of alcohol a week

Symptoms Of Poor
Liver Function

Early Signs

Liver disease is a result of liver damage due to excess alcohol, poor diet and/or obesity, although it can also be genetic.

The early signs of poor liver function can include:

  • Loss of appetite
  • Weight loss
  • Nausea and vomiting
  • Liver pain
  • Poor sleep
  • Feeling unwell
Symptoms Of Liver Disease

More pronounced symptoms appear as the damage to the liver progresses, these include:

  • Yellow skin and eyes, a condition known as jaundice
  • Itchy skin
  • Changes in mood
  • Swelling of the legs and ankles
  • Abdominal pain
  • Chronic Fatigue

You can learn more about the symptoms from the British Liver Trust.

Dr Nicky Keay
the Experts Opinion

The liver is a very important organ, so it is good to check that it is functionally well via a liver function test. Liver function blood tests include many liver enzymes and biomarkers such as bilirubin and albumin. Particular patterns in the levels in these liver function blood tests can identify potential liver problems ranging from inflammatory and infective conditions to mechanical blockage of the gall bladder. As the liver plays a major role in detoxification, excessive alcohol intake can lead to an increase in a specific liver enzyme. Depending on the results from liver function tests, appropriate advice can be given to address any lifestyle issues.

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.

  • What does the liver do?

    The liver is the largest organ in the human body, weighing in at around 1.5 kilos! It has vital roles in human health and without one, we cannot survive.

    The liver’s main functions are associated with the metabolic processes and its role is so vast that it takes part in over 500 functions within your body, including:

    • detoxifying the blood
    • breaking down nutrients
    • converting glycogen to glucose for energy and vice versa for storage
    • producing bile acids to aid digestion
    • removing old and damaged red blood cells from circulation
    • storing nutrients such as iron
    • fighting infections

    As well as playing a huge part in your everyday health, the liver also has an amazing capacity to regenerate itself. That means that liver tissue can grow back after an injury or surgery.

  • What does alcohol do to your liver?

    Excessive alcohol consumption can lead to a condition called alcohol-related fatty liver disease (ARLD) where the organ is unable to break down fats. That’s because when the liver tries to break down the alcohol, the chemical reaction that takes place can cause damage to the liver’s cells, called hepatocytes.

    The liver then tries to repair itself which can lead to inflammation and in the long-term, scarring (cirrhosis). Cirrhosis is permanent and can cause irreversible liver disease and even liver failure.

    Limiting your intake of alcohol is essential. Current guidelines state that we should consume less than 14 units of alcohol per week and that alcohol drinking days should be spread out. Having the odd pint, a glass of wine or an alcopop isn’t likely to cause you much harm, but regular and long-term alcohol consumption will. So, being mindful of what you drink and giving your liver rest days will help to support your liver health.

  • What is Liver Disease?

    There are over 100 different types of liver disease. The most common are alcohol-related liver disease, non-alcoholic fatty liver disease, hepatitis, haemochromatosis, and primary biliary cirrhosis.

    During the early stages, most liver diseases don’t cause any symptoms, so you may be unaware of any damage. However, when symptoms start to show, liver damage and scarring has already occurred, and this is called cirrhosis. Cirrhosis is irreversible and usually occurs when the liver is exposed to continuous and long-term damage.

  • What can I do to keep my liver healthy?

    Permanent liver damage can take years to develop. So, spotting the early signs and making changes to your lifestyle can help the liver repair and regenerate itself.

    Supporting your liver health isn’t as hard as it sounds. You can improve your liver function by:

    • limiting your alcohol intake – less than 14 units per week
    • losing weight if you’re overweight or obese
    • consuming a healthy diet – low fat, whole grains, fibre, lean meat
    • regularly exercising
    • giving up smoking
