Abstract

Two hundred seventy nasopharyngeal aspirates were tested in duplicate with the Ortho Diagnostics, Inc. (Raritan, N.J.), respiratory syncytial virus antigen enzyme-linked immunosorbent assay. The test was sensitive (80 to 82%) and specific (96%) when compared with cell culture. The enzyme-linked immunosorbent assay detected seven antigen-positive specimens not among the 71 specimens that were positive for respiratory syncytial virus in cell culture. A blocking test confirmed those specimens as true positives (specificity, 100%).

摘要

采用美国新泽西州拉里坦市奥索诊断公司的呼吸道合胞病毒抗原酶联免疫吸附试验,对270份鼻咽抽吸物进行了重复检测。与细胞培养法相比,该检测方法的敏感性为80%至82%,特异性为96%。酶联免疫吸附试验在细胞培养中呼吸道合胞病毒呈阳性的71份标本之外,又检测出7份抗原阳性标本。一项阻断试验证实这些标本为真阳性(特异性为100%)。
