Liver
Alkaline Phosphatase (ALP)
Unit: U/LID: M024
What This Test Measures
Enzyme in liver, bone, intestine; bile flow and bone turnover
Conventional vs. Functional Optimal Range
Conventional "Normal"
44-147 U/LYour doctor says you're "fine" anywhere in this range
Functional Optimal
45-100 U/LThis 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
Gabriel's optimal band for ALP is 45-100. Very high ALP with elevated GGT = bile duct issues. Very high ALP with normal GGT = bone disease. Low ALP = zinc deficiency. Functional medicine monitors for bile flow and nutrient status.
When This Test Is High
Bile duct obstruction, liver disease, bone disease (Paget's)
When This Test Is Low
Zinc deficiency, malnutrition, hypothyroidism
Related Conditions
Cholestasis, bone disorders, liver disease
Recommended Follow-Up
If elevated, check GGT to confirm liver source vs. bone; check bilirubin, ultrasound liver
