Why Have I Been Asked to Have This Test?
You may have been invited for this test because you have risk factors for liver disease. Your doctor wants to:
- Check for early signs of liver damage
- Monitor your liver health over time
- Decide if you need more tests, like a liver scan or ultrasound
These risk factors can include:
- Obesity
- Diabetes
- Current or previous higher alcohol consumption
- Previous diagnosis of fatty liver
- Certain medications such as methotrexate
What Is the FIB-4 Test?
The FIB-4 (Fibrosis-4) blood test is a simple, non-invasive way to check how healthy your liver is. It helps estimate if there is any scarring (fibrosis) in your liver.
How Is the Test Done?
The FIB-4 test uses information from:
- Your age
- A blood test called AST
- A blood test called ALT
- Your platelet count
These results are used in a formula to give you a FIB-4 score.
What Do the Results Mean?
Your FIB-4 score falls into one of three categories:
| Low (<1.3) | Unlikely to have significant liver scarring |
| Intermediate (1.3–2.67) | May need further tests (like a liver scan) |
| High (>2.67) | Higher chance of liver scarring – more tests are usually recommended |
Note: The cut-off values may differ slightly depending on your age.
What Happens Next?
- Low score? Great! Your liver is likely in good shape. Your doctor may still check your liver regularly.
- Intermediate or high score? You may need further tests, such as a FibroScan, we will be in contact with you to book in you for the scan.
Is the FIB-4 Test a Diagnosis?
No. The FIB-4 test is a screening tool. It can’t confirm liver disease on its own but helps your doctor decide what to do next.
