目的:探讨儿童发样铅测定的方法及临床应用。方法:采用石墨炉原子吸收光谱法测定儿童发样中铅的含量。结果:该方法灵敏度高,回收率98.1%,CV4.5%,线性范围0～100μg/L。结论:该方法准确可靠,符合《全国临床检验操作规程》(第3版)要求,发样铅测定能真实反映元素的储存水平,可做为超量筛查的一种方法,发样采集方便,容易运输和保存。发铅测定可作为铅中毒筛查项目。
Objective: To explore the method and clinical application of determination of lead in children. Methods: The contents of lead in children hair samples were determined by graphite furnace atomic absorption spectrometry. Results: The sensitivity of this method was high, the recovery was 98.1%, CV4.5% and the linear range was 0 ~ 100μg / L. Conclusion: The method is accurate and reliable, in line with the requirements of the “National Clinical Laboratory Procedures” (3rd edition), hair sample determination can truly reflect the level of elemental storage, can be used as a method of over-screening, hair sample collection convenience , Easy to transport and save. Hair lead determination can be used as lead poisoning screening project.
