Fibrosis-4 Score

About the test :

The FIB-4 score is a non-invasive blood test calculation used to estimate liver fibrosis (scarring)—especially in people with fatty liver disease, hepatitis B or C, or elevated liver enzymes. It helps determine whether advanced liver scarring is unlikely or needs further evaluation.

 

Why should consider this test :

• It helps identify early liver damage without the need for a biopsy.
• It uses routine blood test results, so no extra testing is required.
• It helps screen patients at risk of liver disease quickly and easily.
• It guides doctors on whether further tests or specialist referral are needed.
• It is a simple, cost-effective, and non-invasive way to assess liver health.

 

Who should consider this test :

• People with fatty liver disease or suspected liver problems.
• Patients with diabetes, obesity, or metabolic syndrome
• Individuals with chronic hepatitis B or C
• People who consume alcohol regularly
• Patients with abnormal liver enzyme levels in blood tests

 

More about the test :

It is calculated from four routine lab values:

1. Age
2. AST (SGOT) – liver enzyme
3. ALT (SGPT) – liver enzyme
4. Platelet count

FIB-4 = (Age × AST) / (Platelets × √ALT)

• < 1.3 → Low risk of advanced fibrosis
• 3 – 2.67 → Indeterminate (needs further testing)
• > 2.67 → High risk of advanced fibrosis
