Test Details
Methodology
Nucleic Acid Amplification (NAA)
Result Turnaround Time
1 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Results are for the identification of respiratory syncytial virus (RSV) from upper respiratory specimens.
Limitations
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Specimen Requirements
Specimen
Anterior nasal swab, nasopharyngeal swab, mid-turbinate swab
Volume
1 - 3 mL
Minimum Volume
1 mL (Note: This volume does not allow for repeat testing.)
Container
Anterior nasal swab, nasopharyngeal (NP) swab or mid-turbinate swab in viral/universal transport medium (VTM/UTM) or 0.9% saline
Collection Instructions
Nasopharyngeal (NP) and mid-turbinate swabs: Collect using standard techniques. Place the swab into VTM/UTM and cap tightly.
Anterior nasal swab: Insert the tip of the swab into one nostril. The swab does not need to be inserted far. Insert just until the tip of the swab is no longer visible. Rotate the swab in a circle around the entire edge of your nostril at least three times. Repeat with the second nostril. Insert swab into the 0.9% saline tube and cap tightly.
Stability Requirements
Temperature | Period |
|---|---|
Room temperature | 72 hours |
Refrigerated | 72 hours |
Frozen | >72 hours |
Storage Instructions
Frozen at -20° C (preferred). Refrigerated specimens and room temperature specimens (if received for testing within 72 hours of collection) are also acceptable.
Causes for Rejection
Unacceptable specimens include specimens that are beyond the established stability, improperly labeled, grossly contaminated, broken or with significant leakage in transit or improperly collected or shipped. Substances inhibitory to PCR should not be used to collect specimens; known inhibitory substances include heparin, hemoglobin, ethanol, EDTA concentrations >0.01M. Specimens must be submitted with a swab.
