A liver function test (LFT) 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, such as changing your diet.
What does it check?
A liver profile blood test checks your blood for protein and enzyme biomarkers. The liver proteins are albumin, globulin and total protein. The liver enzymes are alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma GT.
Checking these biomarkers can help identify infections, such as hepatitis B and C, liver disease and other problems. 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.
You can provide the sample for the liver test at any time but we recommend leaving a gap of 72-96 hours if a large amount of alcohol has been consumed.
Checking your liver function at home is quick and easy with our LFT test, and provides detailed insights into your liver health. It contains everything you need, including lancets (to collect blood via a finger prick), test tube/s, sterilising wipes and a pre-paid postage label to return your sample to our lab. The test comes with a full set of easy-to-follow instructions and we also have a video which can help you complete your liver blood test.
There is also an option for a phlebotomy test at checkout, where a healthcare professional will visit your home to draw blood for you.
A Healthy, Balanced Diet

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 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.

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:
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.
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.
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.
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:
