We used an enzyme-linked immunosorbent assay (ELISA) of immunoglobulin G avidity to determine the dengue immune status of 105 pairs of serum samples from patients infected with dengue virus. This study shows that a simple avidity test, for which only one acute-phase serum sample is required, is potentially more useful than the hemagglutination inhibition test for the discrimination of primary from secondary dengue virus infection, whatever the type of dengue antigen used.
我们采用免疫球蛋白G亲和力的酶联免疫吸附测定(ELISA)来确定105对感染登革病毒患者血清样本的登革免疫状态。本研究表明,一种简单的亲和力检测,仅需一份急性期血清样本,无论使用何种类型的登革抗原,对于区分原发性和继发性登革病毒感染而言,可能比血凝抑制试验更有用。
