Fibrosis Index (FIB-4) Reference Guide
This profile includes FIB-4, AST, ALT, platelet count and the AST-to-ALT ratio. FIB-4 is a noninvasive estimate used to help stratify liver-fibrosis risk. Fasting is not required before the verified serum and EDTA collection. The score cannot diagnose fibrosis, cirrhosis or the cause of liver disease by itself.
Why This Test Is Ordered
Reason Description
Know the included results The FIB-4 result is included in this profile. AST and ALT results are included. Platelet count is included in this profile. The AST-to-ALT ratio is included. Understand what FIB-4 uses FIB-4 uses age, AST, ALT and platelets. It helps stratify risk of advanced fibrosis. It is not a direct measurement of scarring. Different clinical settings use different follow-up pathways. Keep interpretation limits clear A score alone cannot diagnose cirrhosis. Intermediate results may need additional assessment. Acute illness can affect enzyme and platelet results. A clinician considers symptoms, history and report ranges.
Symptoms And Who Should Test
Situation Description
People with clinician-directed liver assessment A clinician may request noninvasive fibrosis assessment. Testing reasons depend on individual liver risk. Bring earlier liver reports when available. Testing does not replace urgent symptom assessment. People with metabolic liver-risk factors FIB-4 may support fibrosis risk stratification. Diabetes and obesity need individual clinical context. Abnormal enzymes may need further evaluation. A clinician selects appropriate secondary testing. People reviewing chronic liver disease care Repeat timing depends on the clinical question. Previous trends can help guide follow-up. Alcohol, medicines and infections can matter. Do not change treatment from one score.
Preparation And Interpretation Notes
Topic Guidance
Follow verified collection guidance Fasting is not required before collection. Serum and EDTA blood samples are collected. Follow laboratory collection instructions provided. Confirm any concurrent-test instructions separately. Share useful clinical information List medicines and supplements accurately. Mention recent fever or acute illness. Bring prior liver reports when available. Share known liver disease history. Use results safely Review all results with a clinician. Do not self-diagnose liver fibrosis. Discuss further testing when recommended. Seek urgent care for severe symptoms.
