真菌性水（脓）疱检测体系建立与验证

真菌性水（脓）疱检测体系建立与验证摘要：

真菌性水（脓）疱是指由真菌感染引起的病变，发生率逐年增高并表现出较高的病死率。传统的真菌性水（脓）疱的检测方法存在着繁琐、费时、操作复杂、准确率差等缺陷。因此，建立一个快速、高效、准确的真菌性水（脓）疱检测体系是非常必要和重要的。本文基于PCR和ELISA技术建立并验证了一种新的真菌性水（脓）疱检测体系。

通过对76例真菌性水（脓）疱患者的分析，我们发现了五种可能受到真菌感染的基因。通过PCR检测，我们进一步验证了这些基因的存在，并对它们进行了定量分析。ELISA技术对这些基因的蛋白质表达进行了检测，以及对真菌特异性IgG的水平进行了测量。通过构建多元线性回归模型，我们最终建立了一种真菌性水（脓）疱检测体系。

在144个水（脓）样品中，该体系的检测准确率为92.3％，灵敏度为89.2％，特异性为94.1％。这种检测体系还具有简便、快速和经济的特点，为临床治疗和诊断提供了一种新的选择。
