Respiratory syncytial virus testing capabilities and practices among National Respiratory and Enteric Virus Surveillance System laboratories, United States, 2016

Laboratory testing and diagnostic capabilities differed by whether laboratories self-identified as a CHL or GHL. Many GHLs reported use of RADTs in adults ≥50 years, a less sensitive diagnostic method for this population compared to PCR-based assays. RADT use in adults might miss RSV cases and affect diagnoses and disease burden estimates.
