对于慢性汞中毒的诊断,尿汞数值是一个重要的指标,往往有一些病人其症状体征都明显,而自然排尿汞的数值很低,对于这一类病人也不能轻易下诊断。因此,卫生部在1974年颁布的“五种职工中毒的诊断标准及处理原则”中规定:“根据职业史及临床表现疑有慢性汞中毒而尿汞不高者,可进行驱汞试验,以辅助诊断”。但无具体规定驱汞试验正常数值。为此,我们曾对36名非汞接触者作驱汞试验,并与住院的汞接触者(部分是汞中毒患者)分组对照,作驱汞试验正常比值方法及标准的探讨。
For the diagnosis of chronic mercury poisoning, urinary mercury value is an important indicator, often some patients have obvious symptoms and signs, and the value of natural urination mercury is very low, for this type of patient can not be easily diagnosed. Therefore, the Ministry of Health promulgated in 1974, “five kinds of worker poisoning diagnostic criteria and principles of treatment,” states: “According to occupational history and clinical manifestations of suspected chronic mercury poisoning and urinary mercury is not high, mercury excretion tests can be carried out to Auxiliary diagnosis. ” However, there is no specific requirement for normal values of mercury extinction tests. To this end, we conducted a mercury-for-mercury test on 36 non-mercury-exposed patients and compared them with the grouping of hospitalized mercury-exposed patients (some of whom were mercury-poisoning patients) for methods and criteria for determining the normal ratio of mercury-forcing tests.
