Comprehensive Panels

Liver Function Panel

Unit: U/L, mg/dL, g/dLID: LIV001

What This Test Measures

Liver health: enzymes (ALT, AST, ALP), protein production (albumin), bilirubin

Conventional vs. Functional Optimal Range

Conventional "Normal"

ALT 7-56, AST 10-40, ALP 44-147, Bilirubin 0.1-1.2, Albumin 3.5-5.5 U/L, mg/dL, g/dL

Your doctor says you're "fine" anywhere in this range

Functional Optimal

ALT 10-26 (men), 10-19 (women), AST 10-26, ALP 45-100, Bilirubin 0.5-0.9, Albumin 4.5-5.0 U/L, mg/dL, g/dL

This is where you actually feel great

The gap between these ranges is why you feel terrible with "normal" labs. Conventional medicine waits for disease. Functional medicine optimizes for health.

Gabriel's Take

Liver panel is critical. Gabriel's optimal bands: ALT 10-26 for men and 10-19 for women, AST 10-26 (not up to 40-56). Elevated enzymes flag fatty liver EARLY. ALT>AST = NAFLD (non-alcoholic fatty liver). AST/ALT >2 + elevated = alcoholic liver disease. GGT most sensitive. Albumin 4.5-5.0 reflects good liver protein production.
