ABSTRACT
BackgroundNon-pharmaceutical interventions to prevent the spread of coronavirus disease 2019 also decreased the spread of respiratory syncytial virus (RSV) and influenza. Viral diagnostic testing in patients with respiratory tract infections (RTI) is a necessary tool for patient management; therefore, sensitive and specific tests are required. This scoping literature review evaluated the analytical validity of commercially available sample-to- answer RSV diagnostic tests in different contexts. ContentPubMed and Embase were queried for studies reporting on the analytical validity of tests for RSV in patients with RTI (published January 2005-January 2021). Sensitivity and specificity of RSV tests and information on study design, patient, and setting characteristics were extracted from 77 studies that met predefined inclusion criteria. A literature gap was identified for studies of RSV tests conducted in adult-only populations (5.3% of total sub- records), and in outpatient (7.5%) or household (0.8%) settings. Overall, RSV tests with analytical time >30 min had higher sensitivity (62.5-100%) versus RSV tests with analytical time [≤] 30 min (25.7-100%), this sensitivity range could be partially attributed to the different modalities (antigen versus molecular) used. Molecular-based rapid RSV tests had higher sensitivity (66.7-100%) and specificity (94.3-100%) than antigen-based RSV tests (25.7- 100%; 80.3-100%). SummaryMolecular-based RSV tests should be considered for first-line use when possible, given their high sensitivity and specificity and that adults with RTI typically have low viral load, necessitating a highly sensitive test. This review benefits healthcare professionals by summarizing the diagnostic accuracy data available for commercially available RSV tests. IMPACT STATEMENTViral diagnostic testing in patients with respiratory tract infection is a powerful tool for patient management. This scoping literature review included 77 studies reporting the analytical validity of commercially available respiratory syncytial virus (RSV) diagnostic tests (published January 2005-January 2021) and examined the characteristics of such studies. The data suggest that molecular-based RSV tests have higher sensitivity and specificity than antigen-based tests, thus should be considered for first-line use for timely diagnosis and to detect infections in adults with low level viral load. Future studies should investigate the diagnostic accuracy of RSV tests in adults and in outpatient/household settings.
