Serological diagnostic tests were introduced for detection of immunoresponse against to etiological agents of current infectious diseases. Interpretation criteria for those tests should eliminate unspecific reactions, cross-reactivity with related viruses as well as traces amounts of immunological response against to the past infections. In the case of past hantaviruses infections for obtaining an adequate seroepidemiological data revalidation of this tests are required. In present studies Puumala IgG results obtained in sera from healthy population had been analysed by statistical method and interpretation criteria were recalculated. Panels of 86 sera from forest workers and 47 zoologists working with small mammals were evaluated for hantavirus specific IgG (Hantavirus Puumala ELISA test). Puumala specific antibodies were detected in 7 zoologist's sera and in 5 sera gave equivocal results. All sera collected from forest's workers were negative. Statistical analysis based on negative results in forest workers group suggests that the cut off of the ELISA test suitable for diagnosis of suspected nephropathia epidemica cases is too restrictive for seroepidemiological research of hantavirus in healthy population.
血清学诊断测试被用于检测针对当前传染病病原体的免疫反应。这些测试的解释标准应消除非特异性反应、与相关病毒的交叉反应以及针对既往感染的微量免疫反应。对于既往汉坦病毒感染,为了获得充分的血清流行病学数据,需要对这些测试进行重新验证。在目前的研究中,通过统计方法分析了健康人群血清中获得的普马拉IgG结果,并重新计算了解释标准。对86名森林工人和47名从事小型哺乳动物研究的动物学家的血清样本进行了汉坦病毒特异性IgG(汉坦病毒普马拉ELISA检测)评估。在7名动物学家的血清中检测到普马拉特异性抗体,5份血清结果不明确。从森林工人采集的所有血清均为阴性。基于森林工人组阴性结果的统计分析表明,适用于疑似流行性肾病病例诊断的ELISA检测临界值对于健康人群中汉坦病毒的血清流行病学研究而言限制过严。
