Alkaline phosphatase

An enzyme signal that can come from bone, liver, bile ducts, or other tissues.

這是什麼

ALP is an enzyme found in several tissues, with higher amounts in liver, bile ducts, and bone.[1]

為什麼重要

Bone-related ALP context can appear in high bone turnover or mineralization disorders, but liver and bile sources must be separated.[1]

它會影響哪些判斷

  • Paget disease can involve elevated ALP when bone remodeling is active.[2]
  • Osteomalacia evaluation may include alkaline phosphatase together with vitamin D, calcium, phosphate, PTH, and kidney markers.[3]

解讀陷阱

  • ALP alone cannot identify the source; other tests are often needed.[1]
