Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)
Detection of Respiratory Syncytial Virus (RSV).
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
A negative test does not rule out infection. The specimen must be taken at the appropriate time during infection and properly stored and transported; if optimum conditions are not met, the viral agents may not be detected in the presence of an infection.
1 day (6 hours for UM inpatients and ED)
- RESP. SYNCYTIAL VIRUS; PCR
- RSV by PCR
SWAB: Use flocked swab, dacron or rayon swab to obtain specimen and place into M4-RT transport medium. Refrigerate. BAL FLUID: Place in sterile cup and refrigerate. M6-RT or UTM transport media is also acceptable. Deliver all specimen types to the laboratory as soon as possible. The possibility for virus isolation decreases as the length of storage time increases. Many viral agents will survive at room temperature for several hours; however, for optimum recovery of viruses, please refrigerate; do not freeze.
Specimen will be held for a minimum of 2 weeks to allow additional testing to be added as needed.
