  • Age 18 years or older
  • Diagnosis of chronic liver disease
  • Recent liver function tests (AST, ALT)
  • Platelet count

What are the measure values for the test FIB-4 INDEX

  • Low FIB-4 Index: less than 1.3
  • Indeterminate FIB-4 Index: 1.3 to 2.67
  • High FIB-4 Index: greater than 2.67

What does this test FIB-4 INDEX identify?

The FIB-4 index is a non-invasive blood test that helps in identifying the degree of liver fibrosis in patients with chronic liver disease, specifically in those with hepatitis C virus (HCV) infection. The index is calculated using four simple laboratory tests: age, platelet count, AST (aspartate aminotransferase) level, and ALT (alanine aminotransferase) level.

The FIB-4 index is used to assess the risk of advanced fibrosis or cirrhosis in patients with chronic liver disease. It is a convenient and cost-effective tool for clinicians to determine the severity of liver fibrosis without the need for more invasive procedures like liver biopsy.

Why is this test FIB-4 INDEX taken?

Why is the FIB-4 Index Test Taken?

The FIB-4 Index test is taken to assess the degree of liver fibrosis in patients with chronic liver disease, particularly those with hepatitis C or non-alcoholic fatty liver disease (NAFLD).

This test is important because liver fibrosis is a key factor in determining the progression of liver disease and the need for treatment. The FIB-4 Index is a simple and non-invasive way to estimate liver fibrosis based on routine blood tests, making it a valuable tool for monitoring patients with liver disease over time.

By regularly monitoring the FIB-4 Index, healthcare providers can track changes in liver fibrosis and make informed decisions about treatment options and disease management.

Popular FAQs on Test

The FIB-4 index is a blood test used to assess the degree of liver fibrosis in patients with chronic liver disease. It is a non-invasive test that calculates a score based on the patient's age, aspartate aminotransferase (AST) level, alanine aminotransferase (ALT) level, and platelet count.
The FIB-4 index is calculated using the following formula: (Age x AST) / (Platelet count x √ALT). The resulting score can help determine the degree of liver fibrosis in a patient.
A high FIB-4 index score typically indicates a higher degree of liver fibrosis in a patient. It may suggest the presence of advanced liver disease, such as cirrhosis, and may prompt further evaluation or treatment.
While the FIB-4 index is a useful tool for assessing liver fibrosis, it is not a definitive diagnostic test. It is often used in conjunction with other clinical and laboratory assessments to help guide treatment decisions for patients with chronic liver disease.
