The sensitivities and specificities of an immunofluorescence assay and an enzyme immunoassay for detection of antibodies specific for severe acute respiratory syndrome coronavirus (SARS-CoV) were compared for 148 laboratory-confirmed SARS cases. The appearance and persistence of SARS-CoV-specific antibodies were assessed, with immunoglobulin G detected in 59% of samples collected within 14 days and persisting for 60 to 95 days after the onset of illness.
针对148例实验室确诊的严重急性呼吸综合征冠状病毒(SARS-CoV)病例,比较了免疫荧光测定法和酶免疫测定法检测SARS-CoV特异性抗体的敏感性和特异性。评估了SARS-CoV特异性抗体的出现和持续情况,在发病后14天内采集的样本中,59%检测到免疫球蛋白G,且在发病后60至95天内持续存在。
