| 摘 要： | 调查了125例2－5岁儿童铅中毒状况，测定其全血铅含量和头发铅含量，以全血铅含量为标准，应用诊断试验评价方法评价头发铅测定的应用价值。结果表明，该试验的灵敏度可达88．3％，应用串联试验，即同时测定头发中锌、铁、钙含量，可将该试验的特异度提高至81．8％，阳性预测值达69．6％，阴性预测值达78．8％。 |
| 关 键 词： | 头发 铅含量 测定 灵敏度 特异度 预测值 儿童 铅中毒 全血铅含量 应用价值 评价方法 |

| Abstract: | children aged from 2 to 5 years old had been surveyed.The content of lead in whole blood samples and hair samples from the children was determined.Comprared to the whole blood lead content determination as the gold standard,the application value of hair lead content determination was estimated by diagnostic test method.The results showed that the testing sensitivity was 88 3%.The specificity of serial testing was increased to 81 8%,combined with determination of zinc,iron and calcium content in hair. |
| Keywords: | hair lead determination sensitivity specificity predicative value |
