肠道蠕虫(钩、鞭虫)感染的患者,感染度越低,用定透法检查粪便蠕虫卵的检漏率越高。本文用指数曲线拟合的方法找出定透法检漏率与肠道钩、鞭虫不同感染度数量变化关系,并建立了推算检漏人数的公式。由此得出结论:当肠道钩、鞭虫感染度低时,单用定透法检查不能反映人群真实感染情况,宜与盐浮法联合检查。
Intestinal worm (hook, whipworm) infected patients, the lower the level of infection, fixed stool method to check the higher the leak rate of stool eggs. In this paper, the exponential curve fitting method to find Ding-law leak rate and gut hooks, whipworm the number of different changes in the relationship between infection, and establish a formula to estimate the number of leaks. This concludes: When the intestinal hook, whipworm infection is low, the single fixed-law test does not reflect the real population of people infected with the situation, should be combined with the salt float inspection.
