尿铅含量可以反映机体对铅吸收的程度,是铅中毒诊断的重要参考指标之一。现行国家诊断标准规定以收集24小时尿检查为准确,正常值在0.08毫克/升以下。对有铅接触史、工龄较长、临床症状明显,而尿铅量不高时,可进行驱铅试验,以辅助诊断。但是,至今对驱铅试验正常值范围尚未统一。为了探讨本地区正常人尿铅含量,以及驱铅试验后的尿铅水平,1979年4月～5月,我们作了此项试验,兹报道如下。
Urine lead content can reflect the extent of the body’s absorption of lead, is an important reference for the diagnosis of lead poisoning indicators. The current national diagnostic criteria to collect 24-hour urine examination is accurate, the normal value of 0.08 mg / L or less. Lead exposure history, longer working age, clinical symptoms, and urinary lead levels are not high, the lead-off test can be carried out to assist diagnosis. However, to date, the normal range of lead-removing test has not been unified yet. In order to explore the normal area of ?? urine lead levels, as well as lead urinary lead levels after the test, April 1979 ~ May, we made this test, it is reported below.
