The FilmArray respiratory virus panel detects 15 viral agents in respiratory specimens using polymerase chain reaction. We performed FilmArray respiratory viral testing in a core laboratory at a regional children's hospital that provides service 24 hours a day 7 days a week. The average and median turnaround time were 1.6 and 1.4 hours, respectively, in contrast to 7 and 6.5 hours documented 1 year previously at an on-site reference laboratory using a direct fluorescence assay (DFA) that detected 8 viral agents. During the study period, rhinovirus was detected in 20% and coronavirus in 6% of samples using FilmArray; these viruses would not have been detected with DFA. We followed 97 patients with influenza A or influenza B who received care at the emergency department (ED). Overall, 79 patients (81%) were given oseltamivir in a timely manner defined as receiving the drug in the ED, a prescription in the ED, or a prescription within 3 hours of ED discharge. Our results demonstrate that molecular technology can be successfully deployed in a nonspecialty, high-volume, multidisciplinary core laboratory.
FilmArray 呼吸道病毒检测试剂盒采用聚合酶链反应技术,可检测呼吸道标本中的 15 种病毒。我们在一家区域儿童医院的核心实验室中进行了 FilmArray 呼吸道病毒检测,该实验室每天 24 小时、每周 7 天提供服务。与之前在现场参考实验室使用直接荧光检测(DFA)进行的检测相比,平均和中位数的周转时间分别为 1.6 小时和 1.4 小时,而 DFA 可检测 8 种病毒。在研究期间,FilArray 检测到 20%的样本中存在鼻病毒,6%的样本中存在冠状病毒;而这些病毒使用 DFA 是无法检测到的。我们对在急诊科接受治疗的 97 例甲型流感或乙型流感患者进行了随访。总体而言,79 例(81%)患者及时接受了奥司他韦治疗,及时治疗的定义为在急诊科接受药物治疗、在急诊科开具处方或在急诊科出院后 3 小时内开具处方。我们的研究结果表明,分子技术可以成功应用于非专业、高容量、多学科的核心实验室。
