*本系列专为新移民而写。都是网友发QQH到我的信箱里常问的问题。因悄悄话的版面有限，把答复的内容写在自己的博客里，并公开贴在健康养生坛。到目前为止已完成六篇。感谢网友、健康坛版主和亲爱的网管大人的热心支持（只写了一部分时就被贴出），这是最后的完整版，介绍常见的12项检查内容。它是最费时费力的一篇---要制表，要核对数据和单位。无高深的医学知识，只是把它们归类整理出来，供参考之用。但请参照自己的检验报告里的正常范围，因为各实验室的检验方法和仪器会有误差，而且需要医生结合你的情况来判读你的检验结果。千万不要只看到自己的某一项指标偏高或偏低就心慌了---单方面一个指标的不正常有时是没有临床意义的。请咨询你的医生，由医生来下结论。

谢谢大家，特别是给我留QQH的网友的信任。下一篇的题目是：各种疼痛的英文表达（5th vital sign---pain)(也是一网友要求的。但最近较忙，尽量一星期后完成。）*
