What is a Liver Function Test (LFT)?

A liver function test (LFT) is a simple blood test that evaluates the levels of proteins, enzymes and other important substances manufactured by the liver. These levels help to analyse the liver health and ascertain if there is any damage or inflammation. ²

It usually checks levels of ALT, AST, ALP, bilirubin, and albumin which are the key markers of liver health.

Why Is Your Liver Health Important

Your liver needs to be in top-notch condition because it caters to very important functions in the body, like breaking down nutrients and manufacturing essential proteins. An unhealthy liver will lead to fatigue, digestive issues and even death in extreme cases. 

Ignoring early signs can lead to problems like cirrhosis, fatty liver disease, or hepatitis. That's why it's so important to get a liver function test on time.

7 Signs That Depict You May Need a Liver Function Test

There are some signs you need to watch out for: ³

1. Persistent Fatigu

If you're always tired and don't know why, it could be a sign that your liver isn't working properly. When the liver doesn't work right, toxins build up, which makes you tired.

2. Yellowing of Skin or Eyes (Jaundice)

Jaundice is a clear sign that something is wrong with the liver. It happens when the bilirubin levels in the blood go up.

3. Abdominal Pain or Swelling

If you have pain in the upper right abdomen or unexplained bloating, it could mean that your liver is inflamed or enlarged.

4. Dark Urine or Pale Stools

Changes in the colour of urine or stool may indicate problems with bile flow, which are often caused by liver problems.

5. Nausea and Loss of Appetite

Early warning signs may include stomach pain, nausea, or a sudden loss of appetite.

6. Sudden Unexplained Weight Loss

If you lose weight quickly without trying, it could mean you have liver problems.

7. Itchy Skin (Pruritus)

Chronic itching without a rash could be caused by bile salt building up in the liver.

If you have any of these symptoms, you should see a doctor and think about getting a liver function test.
