背景：性传播感染（STI）的全球增加使得有必要寻求促进快速和微创诊断的公共卫生策略。目的是评估用于STI诊断的阴道和子宫颈样本之间的一致性。
方法：对在我们的参考区域就诊的女性的阴道和宫颈样本进行了回顾性横断面研究，这些女性在研究期间症状提示外阴阴道炎或进行STI筛查。
结果：共分析了130个配对样本；57个和59个样本对阴道和宫颈标本呈阳性（Kappa指数为0.969（标准误差=0.022）。阴道样本的灵敏度为96.5％（IC95％：87.2-99.4），特异性为100%(IC95%:93.0-100)。
结论：在我们的环境中，在阴道样本中引入STI筛查可以促进快速有效的诊断，并可以早期治疗STI。此外,它有助于在社区环境中进行样本收集和诊断，对于最佳筛选至关重要。
BACKGROUND: The global increase in sexual transmitted infections (STI) makes it necessary to seek public health strategies that facilitate rapid and minimally invasive diagnosis. The objective was to evaluate the concordance between vaginal and endocervical samples for STI diagnosis.
METHODS: A retrospective cross-sectional study was carried out on vaginal and endocervical samples from women attended in our reference area with symptoms suggestive of vulvovaginitis or for STI screening during the study period.
RESULTS: A total of 130 paired samples were analyzed; fifty-seven and 59 samples were positive for vaginal and endocervical specimens (Kappa index of 0.969 (Standard error = 0.022). The sensitivity of the vaginal samples was 96.5% (IC95%: 87.2-99.4), with a specificity of 100% (IC95%: 93.0-100).
CONCLUSIONS: The introduction of STI screening in vaginal samples in our environment can facilitate rapid and effective diagnosis and allow early treatment of STI. Additionally, it facilitates sample collection and diagnosis in the community setting, essential for optimal screening.
