一位急性胰臟炎患者主訴上腹部劇烈疼痛並放射至背部。下列哪項血液檢驗值最能診斷此狀況？
A client with acute pancreatitis presents with severe epigastric pain radiating to the back. Which serum laboratory value is most indicative of this condition?
- AElevated white blood cell count白血球計數升高
- BDecreased serum calcium血清鈣濃度降低
- CElevated serum amylase✓ 正解血清澱粉酶升高
- DDecreased serum glucose血清葡萄糖濃度降低

急性胰臟炎時，胰臟細胞損傷導致澱粉酶溢出至血液中。血清澱粉酶上升是此診斷的黃金標準，通常在發作後 12-24 小時內顯著升高。雖然白血球上升或低血鈣也可能出現，但缺乏澱粉酶上升的特異性，無法作為確診指標。
In acute pancreatitis, pancreatic cell injury causes amylase to leak into the bloodstream. An elevated serum amylase is the gold-standard diagnostic indicator for this condition, typically rising significantly within 12-24 hours of onset. Although leukocytosis or hypocalcemia may also occur, they lack the specificity of elevated amylase and cannot serve as confirmatory diagnostic markers.
✦ 台美臨床差異
美台臨床對於澱粉酶(Amylase)與解脂酶(Lipase)的依賴度不同，美國現在更傾向使用解脂酶作為首選指標，因其專一性較高。
