What is a Liver Function Blood Test?

Liver function tests or LFTs are blood tests that measure chemicals in the blood that are associated with the liver. They can give an indication of whether there is a change in the way the liver is working and can therefore help to identify any problems.

A liver function test is an important component of our patient health screens. Your doctor may recommend a health screen to investigate potential reasons as to why you are not feeling yourself. Do not worry about determining for yourself which if any blood test you need. This is something that your doctor will be able to determine and explain during your consultation.

All our blood tests are available same day with some of the fastest results in London. One of our doctors will take the time to explain to you what your test results mean and put in place any approprate next steps based on those results.

* Please note that the lab results are estimates and can vary. Tests taken after 1pm will be classified as the following day for timing purposes. You will receive a written analysis of your results within 1 working day of them being available from the laboratory. If you have multiple tests then we shall wait to report on them together unless the first results highlight any reason for concern. Sometimes the preliminary results will determine that additional tests need to be carried out on your sample. If this is the case then your results will take longer. There is no additional charge for this service.

What does the Liver do?

The liver is an amazing organ that performs several functions within the body, including:

  • Storing fuel for the body in the form of glycogen
  • Making clotting factors which help your blood clot
  • Makes bile to store in the gallbladder which helps your body to digest fats and proteins
  • Processing alcohol, toxins and many medicines

What illnesses can a Liver Function Test diagnose?

The LFT blood test is actually a panel of tests that look at various chemicals and processes from the liver. The test includes:

  • ALT (alanine aminotransferase) and AST (aspartate aminotransferase) - are enzymes found in liver cells (and some other body tissues). They may rise when there is inflammation or damage to the liver cells. This happens in liver infections (eg hepatitis A, B and C), alcohol abuse, fat deposit due to obesity and liver damage caused by medications (including antibiotics, herbal medicine and statins) .
  • ALP (alkaline phosphatase) - this is found in liver cells as well as in bone and the placenta. ALP can rise with liver problems due to gallstones. 
  • GGT (gamma glutamyltransferase) - this level will rises when gallstones block the bile duct that drains bile from the liver. It can also be increased by heavy alcohol consumption.  
  • Albumin - this is a protein made by the liver and can be low in inflammation or if the liver is not working well.
  • Bilirubin - this is made from haemoglobin, which is released when red blood cells are broken down. When there is too much bilirubin the skin and whites of the eyes can become yellow known as jaundice. Various liver conditions can raise the bilirubin level in the blood such as alcohol excess, hepatitis or gallstones.

Can a Liver Function Test show if I'm drinking too much?

Drinking an excessive amount of alcohol can cause inflammation and eventually scarring of your liver. A liver function blood test may show this inflammation but a normal results isn't a reliable way of knowing that your alcohol intake is safe. If you are unsure if you are drinking too much then talk to one of our doctors.
