白血球增多（Leukocytosis）是身體對急性感染的正常發炎反應，是臨床診斷感染最基礎的實驗室數據。雖然在極嚴重感染或免疫功能低下時可能出現 Leukopenia，但 Leukocytosis 仍為最普遍的初始指標。
Leukocytosis is the normal inflammatory response of the body to acute infection and is the most basic laboratory finding for the clinical diagnosis of infection. Although leukopenia may occur in severe infection or in immunocompromised clients, leukocytosis remains the most universal initial indicator.
