铅中毒的早期诊断是防治铅中毒的重要环节。近几年来,国内外在这方面的研究有不少新的进展,获得了一些特异性较高、敏感性较强的指标,有的已列为铅中毒诊断指标和预防性体检的常规项目。对于某些习已常用的实验室检验项目,经多年使用的经验积累和检查方法的改进,其使用价值方面亦有新的评价。本文就有关铅中毒早期诊断指标方面的研究近况简述如下。一、反映铅进入机体内代谢水平的指标人体自外界环境摄取铅。其途径有:铅及其化合物以铅烟和铅尘的形式通过呼吸道进入人体;铅也可以由于手和食物被污染而通过消化道进入人
Early detection of lead poisoning is an important part of prevention and treatment of lead poisoning. In recent years, there are quite a few new developments in this field both at home and abroad. Some high-specificity and high-sensitivity indicators have been obtained, some of which have been listed as routine items for the diagnosis of lead poisoning and preventive medical examination. For some commonly used laboratory test items, after years of experience and improvement of inspection methods, its value is also a new evaluation. This article on the early diagnosis of lead poisoning indicators recent research is as follows. First, reflect the lead into the body’s metabolism indicators of the body from the external environment, lead intake. The way: lead and its compounds in the form of lead and lead dust through the respiratory tract into the body; lead can also be contaminated by hand and food through the digestive tract into people
