Test Details
Methodology
Shell vials or equivalent multiwell plate culture with fluorescent antibody staining
Result Turnaround Time
2 - 4 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.
Test Includes
Shell vials or equivalent multiwell plate cell culture; identification (additional CPT codes/charges will apply) if culture results warrant. This culture is for the isolation of influenza A and influenza B, other viral agents will not routinely be detected. CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed. If a virus other than those specified for this virus-specific culture are recovered, identification will be made, and an additional charge will apply. The client will not be telephoned to approve this charge.
Use
Isolate and identify influenza virus as an etiologic agent in cases of influenza and viral pneumonia
Special Instructions
If reflex testing is performed, concomitant CPT codes/charges will apply.
Submit one specimen per test requested. Specify the exact specimen source/origin (eg, nasopharynx). Indicate a specific test number on the test request form. Do not use transport devices beyond their expiration date.
