Serum calcium

這是什麼

A calcium blood test measures calcium in blood, where only a small portion of body calcium is found.^[1]

為什麼重要

Blood calcium helps interpret parathyroid, kidney, vitamin D, and cancer-related contexts, but it is not a bone calcium score.^[1,2]

它會影響哪些判斷

• High blood calcium can be related to parathyroid disorders, certain cancers, Paget disease, excessive vitamin D exposure, or other conditions.^[1]
• Low blood calcium can be related to low vitamin D, kidney disease, parathyroid problems, low protein, or other contexts.^[1]

解讀陷阱

• Total calcium and ionized calcium are different measurements; albumin, illness, supplements, and medicines can affect interpretation.^[1]
