What do your Alkaline Phosphatase levels mean?
The short answer
Nobody we follow has said what your Alkaline Phosphatase should be. It comes up on the shows, but never with a number.
Your lab prints 40–129 U/L. That range exists to catch disease, not to describe your best.
What Alkaline Phosphatase measures
An enzyme found all over your body. Your liver, bile ducts and bones carry the most.
It rises when something blocks bile flow, or when bone rebuilds itself.
Checked against MedlinePlus — Alkaline Phosphatase.
