Liver
Total Bilirubin
Unit: mg/dLID: M025
What This Test Measures
Breakdown product of red blood cells; processed by liver
Conventional vs. Functional Optimal Range
Conventional "Normal"
0.1-1.2 mg/dLYour doctor says you're "fine" anywhere in this range
Functional Optimal
0.5-0.9 mg/dLThis 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
Mildly elevated bilirubin (1.0-2.0) often = Gilbert's syndrome (benign genetic variant, actually protective). Very high = liver disease or hemolysis. Gabriel's optimal band is 0.5-0.9 for liver conjugation and bile flow.
When This Test Is High
Gilbert's syndrome (benign), hemolysis, liver disease, bile duct obstruction
When This Test Is Low
Usually not significant
Related Conditions
Jaundice, liver disease, hemolytic anemia
Recommended Follow-Up
If elevated, check direct/indirect bilirubin, liver enzymes, CBC; rule out hemolysis
