Tests that measure Alanine Aminotransferase

FIB-4 Index Panel with Reflex to Enhanced Liver Fibrosis ELF Score

Laboratory
Quest Diagnostics
Test code
12734
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

This reflex provides a cost-effective, medically justified, and guideline supported approach to evaluating a patient at risk of NAFLD with liver fibrosis. If the FIB-4 index is ≥1.30, the ELF score is performed.

Liver Fibrosis Fibrosis-4 FIB-4 Index Panel

Laboratory
Quest Diagnostics
Test code
30555
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

The FIB-4 index is a simple non-invasive approach using selected laboratory measures (AST, ALT, platelet count) in combination with patient age to assess if an individual is at higher risk for advanced liver fibrosis (F3-F4).

Alanine Aminotransferase ALT

Laboratory
Quest Diagnostics
Test code
823
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

Alanine Aminotransferase (ALT) measurements are particularly useful in the diagnosis and management of certain liver diseases, e.g., viral hepatitis and cirrhosis. ALT activity in tissue is generally much lower than aspartate aminotransferase (AST) activity and is found in highest concentrations in the liver. Significant elevations of ALT occur only in diseases of the liver. ALT is often measured in conjunction with AST to determine whether the source of the AST is the liver or the heart. ALT is normally not elevated in cases of myocardial infarction, i.e., a normal ALT, in conjunction with an elevated AST, tends to suggest cardiac disease. However, slight elevations of ALT may occur if an infarct destroys a very large volume of heart muscle.
