Comprehensive blood test to detect and monitor non-alcoholic fatty liver disease (NAFLD) risk.
This test measures alanine transaminase (ALT), aspartate aminotransferase (AST), and platelet levels. These, along with your age, determine your risk for advanced liver fibrosis. A FIB4 Index ≥1.30 triggers a free Enhanced Liver Fibrosis test on your existing sample. Early diagnosis allows for treatment to reverse or slow disease progression, preventing NASH, fibrosis, and cirrhosis.

Who Is This For?
Anyone wanting to check specific health markers. People monitoring known conditions or treatment effectiveness. Those who want targeted testing rather than a comprehensive panel. Individuals following up on previous abnormal results or investigating specific symptoms.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
7A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.
An enzyme found in the liver, heart, and muscles. While less liver-specific than ALT, elevated AST can indicate liver damage, heart attack, or muscle injury. The AST/ALT ratio helps distinguish between different liver conditions.
Calculated score based on ALT, AST, platelet levels, and age; indicates risk of advanced liver fibrosis.
Calculated score based on hyaluronic acid (HA), Type III procollagen peptide (PIIINP), and tissue inhibitor of matrix metalloproteinase 1 (TIMP-1) levels; further assesses fibrosis severity if FIB-4 is high.
Marker of liver fibrosis; elevated levels suggest increased fibrosis.
Marker of collagen synthesis; elevated levels suggest increased fibrosis.
Measures the number of platelets, small cell fragments essential for blood clotting. Low platelets increase bleeding risk, while high platelets may increase clot risk. Important for monitoring clotting disorders and medication effects.
