Abstract

Immunofluorescence staining of centrifugation-enhanced shell vial (SV) cultures for respiratory viruses (RV) after 24 h of incubation, rather than the more commonly prescribed times of 48 h and 5 days, allowed for the detection of 77% of the RV-positive specimens that would ordinarily not have been detected as positive until 48 h. Staining SVs at 24 h also permitted earlier detection of viruses that were missed by rapid antigen detection methods.

摘要

对呼吸道病毒(RV)进行离心增强空斑培养(SV),培养24小时后进行免疫荧光染色,而非更常用的48小时和5天的培养时间,能够检测出77%的RV阳性标本,这些标本通常在48小时前不会被检测为阳性。在24小时对SV进行染色,还能更早地检测出快速抗原检测方法遗漏的病毒。
