7. Iron Tests（检查血中的铁）:

        是测定血中铁的含量、血液运输铁的能力和铁的儲存量。用于各型贫血的鉴别诊断（如：缺铁性贫血、再生障碍性贫血、铁粒幼红细胞贫血和慢性溶血性贫血等）。需空腹12小时抽静脉血检查。

11.Cardiac marker（心脏病指标） :

        虽然仍有医院、有医生在做CPK-MB test，但这里只介绍一个目前被认为是检测急性心肌梗塞（Acute Myocardial Infarction）最灵敏的检测法---Troponin test (Troponin I (肌钙蛋白I) onset: 4-6 hrs, peak: 12-24 hrs, return to normal: 4-7 days).

0.00--0.09	Normal
0.10--0.60	Possible indication of myocardial damage,  unstable angina, congestive heart failure, myocarditis, cardiac surgery or invasive testing. Clinical correlation is required.
>0.60	May indicate significant myocardial injury. Clinical correlation is required.

12.Cancer marker（癌症指标）:

      这些指标不是诊断癌症的专属的、特异性指标，很多非肿瘤的、偶然的身体变化也可能使这些指标不正常，所以它们只能作为一种参考或评估治疗前后的参考值。请不要心慌，让自己的医生根据具体情况来判读结果。

test	中文	Reference range in US Units	Clinical significance
AFP (Alpha fetoprotein)	甲胎蛋白	<10 µg/L	Often elevated in liver cancers (hepatocellular) and testicular cancers (non-seminomatous). Raised levels are also present during pregnancy or some gastrointestinal cancers.
CA 15-3	CA 15-3	<30 IU/L	Increased in metastatic breast. Raised levels are also present in other non-malignant conditions (eg. cirrhosis, benign diseases of ovaries & breast).
CA 19-9	CA 19-9	<37 IU/L	Increased in pancreatic,hepatobiliary,gastric,and colorectal cancer,gallstones .Its level is best evaluated along with CEA marker test.
CA125	CA125	<35 IU/L	Increased in colon, upper gastrointestinal(GI),ovarian, and other gynecologic cancers; during menstruation,pregnancy or individuals with ovarian cysts,pericarditis,hepatitis,cirrhosis of the liver or peritonitis.
Carcinoembryonic antigen (CEA)	癌胚抗原	0-2.5 µg/L(nonsmoker); 0-5 µg/L(smoker)	CEA was first identified in colon cancer. Elevated CEA levels are found in a variety of cancers other than colonic, including pancreatic, gastric, lung, and breast. It is also detected in benign conditions including cirrhosis, inflammatory bowel disease, chronic lung disease, and pancreatitis.
PSA (Prostate-Specific Antigen)	前列腺特异性抗原	0-4 ng/ml	PSA is prostate-specific, not cancer-specific. A variety of conditions can raise PSA levels: prostatitis (prostate inflammation), benign prostatic hypertrophy (prostate enlargement), and prostate cancer.

*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（the 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。）*

You did a great job. It helps me a lot.

A little suggestion: it will be nice if you can contribute more time to give a review for each value - what happen if a value is high/low.
