Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Respiratory syncytial virus (RSV) is an infectious pathogen that infects the human respiratory tract causing an influenza-like illness. Most healthy people spontaneously recover from RSV infection in 1 to 2 weeks, but infection can be severe in infants, young children, and older adults. The virus is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children under 1 year of age in the United States. .It is recognized increasingly as a frequent cause of respiratory illnesses in older adults.
RSV can be detected by polymerase chain reaction in upper and lower respiratory tract specimens. Nasopharyngeal swabs or aspirates are the preferred specimen types for detection of RSV RNA. Nasal swabs may not yield as high detection rate as those of nasopharyngeal specimens for molecular detection of RSV RNA. Bronchoalveolar lavage fluid, bronchial washings, endotracheal aspirate, and sputum are suitable specimens for detection of RSV infection of the lower respiratory tract.

Undetected
Interpretation
Provides information to assist in interpretation of the test results
Provides information to assist in interpretation of the test results
A "Detected" result indicates that respiratory syncytial virus (RSV) RNA is present and suggests the presence of RSV infection in the symptomatic patient.
An "Undetected" result indicates that RSV RNA is absent in the patient's specimen.
An "Inconclusive" result indicates that the presence or absence of RSV RNA in the specimen could not be determined with certainty after repeat testing in the laboratory, possibly due to inhibition of polymerase chain reaction from interfering substances present in the respiratory tract specimen. Submission of a new specimen for testing is recommended when clinically indicated.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
The sensitivity of the assay is dependent on the timing of the specimen collection (in relation to symptom onset), quality, and type of specimen submitted for testing. This test should not be performed unless the patient meets clinical and epidemiologic criteria for testing.
The test is specific for detection of respiratory syncytial virus (RSV), and positive test results do not exclude the possibility of concurrent infection with other respiratory viruses, such as SARS-CoV-2, influenza A and B viruses.
Undetected (ie, negative) results do not rule out RSV infection in patients and should not be used as the sole basis for treatment or other patient management decisions. Results should be correlated with patient's history and clinical presentation. This assay detects both viable (ie, replicating) and nonviable virus.

Method Description

Describes how the test is performed and provides a method-specific reference
This assay is a laboratory-developed, TaqMan probe-based, real-time, reverse transcription polymerase chain reaction (PCR) assay using a commercially available test designed for qualitative detection of respiratory syncytial virus (RSV) in human upper and lower respiratory tract specimens. Viral target-specific primers and probe are used to amplify and detect the matrix protein (M)-encoding sequence of RSV. Clinical samples undergo automated sample preparation (nucleic acid extraction and purification), during which viral nucleic acid in patient samples and added internal control RNA molecules are simultaneously extracted. Nucleic acid is released by the addition of proteinase and lysis reagent to the sample. The released nucleic acid binds to the silica surface of the added magnetic glass particles. Unbound substances and impurities, such as denatured protein, cellular debris, and potential PCR inhibitors, are removed with subsequent wash steps, and purified nucleic acid is eluted from the magnetic glass particles with elution buffer at elevated temperature. Known positive and negative controls are processed in the same way in each assay run.(Package insert: cobas Influenza A/B and RSV UC: Qualitative nucleic acid test for use on the cobas 6800/8800 Systems.
