Use

Results are for the identification of respiratory syncytial virus (RSV) from upper respiratory specimens.

Special Instructions

Not provided.

Limitations

This test was developed and its performance characteristics were determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. Results should be interpreted in the context of clinical findings and should not be used as the sole basis for diagnosis or patient management. Specimens collected using substances inhibitory to PCR such as heparin, hemoglobin, ethanol, and high concentrations of EDTA may lead to inaccurate results.

Specimen

Nasal Swab

Volume

1 - 3 mL

Minimum Volume

1 mL

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.

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.
