*本係列專為新移民而寫。都是網友發QQH到我的信箱裏常問的問題。因悄悄話的版麵有限，把答複的內容寫在自己的博客裏，並公開貼在健康養生壇。到目前為止已完成六篇。感謝網友、健康壇版主和親愛的網管大人的熱心支持（隻寫了一部分時就被貼出），這是最後的完整版，介紹常見的12項檢查內容。它是最費時費力的一篇---要製表，要核對數據和單位。無高深的醫學知識，隻是把它們歸類整理出來，供參考之用。但請參照自己的檢驗報告裏的正常範圍，因為各實驗室的檢驗方法和儀器會有誤差，而且需要醫生結合你的情況來判讀你的檢驗結果。千萬不要隻看到自己的某一項指標偏高或偏低就心慌了---單方麵一個指標的不正常有時是沒有臨床意義的。請谘詢你的醫生，由醫生來下結論。

謝謝大家，特別是給我留QQH的網友的信任。下一篇的題目是：各種疼痛的英文表達（5th vital sign---pain)(也是一網友要求的。但最近較忙，盡量一星期後完成。）*
