A muscle-waste product measured in blood and used to estimate kidney filtration.

這是什麼

Creatinine is a waste product from muscle activity that kidneys remove from blood.[1,2]

為什麼重要

Blood creatinine is often used to estimate eGFR, but creatinine alone is not the best kidney-function measure.[1,2]

它會影響哪些判斷

  • Creatinine depends on muscle mass, diet, age, activity, and clinical context.[1,2]

解讀陷阱

  • A single high creatinine result cannot diagnose a specific condition.[1,2]
