Provided herein is a method of detecting the presence of influenza virus in a sample while minimizing false positives due to presence of one or more other pathogens in the sample, the method including measuring the enzymatic activity of neuraminidase (NA) in the sample under one or more differentiating conditions selected from the group consisting of pH, binding to anti-NanA antibody, size exclusion, hemagglutinin (HA) binding, chemical inhibition, and combinations thereof.
本文提供了一种检测样品中是否存在流感病毒的方法,同时最大限度地减少因样品中存在一种或多种其他病原体而导致的假阳性,该方法包括在一种或多种选自 pH 值、与抗 NanA
抗体的结合、尺寸排除、血凝素(HA)结合、
化学抑制及其组合的区分条件下测量样品中
神经氨酸酶(NA)的酶活性。
