Test Details
Methodology
Inoculation of specimen into shell vials or equivalent multiwell plate cell cultures, and identification by DFA or other methods
Result Turnaround Time
4 - 5 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 charges/CPT code[s] may apply) by fluorescent antibody or other methods if culture results warrant. CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed. The culture is for the isolation of common respiratory viruses that include adenovirus; influenza A; influenza B; parainfluenza 1, 2, and 3; and respiratory syncytial virus. Other viruses will not be routinely detected; however, if a virus other than those specified for this culture is recovered, identification will be made and an additional charge will apply. The client will not be contacted to approve this charge.
Use
Aid in the diagnosis of viral respiratory disease
Special Instructions
Submit one specimen per test requested. Specify the exact specimen source/origin (eg, nasopharynx). Indicate a specific test number on the request form. Age of patient, relevant vaccinations, and pertinent clinical history are helpful. Whenever a viral etiology is suspected and whenever appropriate, acute and convalescent serum should be collected for viral serology tests.

Custom Additional Information
Give date of onset of illness, date of collection, and brief clinical description or the provisional diagnosis.
Specimen Requirements
Specimen
Nasopharyngeal (NP) aspirate or wash, NP swab
Volume
1 mL fluid or one swab in transport
Container
Viral, Chlamydia, or Mycoplasma culture transport provided by LabCorp, or other appropriate transport medium; sterile screw-cap tube or container for nasal washings or bronchoalveolar lavage
Collection Instructions
Specimen should be collected during acute phase of disease.
Throat swab: Carefully rub the posterior wall of the nasopharynx with a dry, sterile swab. Avoid touching the tongue or buccal mucosa. Place swab in viral transport tube.
Reference Range
No virus isolated
Storage Instructions
Specimen must be kept cold and moist.
Causes for Rejection
Bacterial swab specimen; specimen received in grossly leaking transport container; dry specimen; specimen submitted in fixative or additives; specimen received in expired transport media or incorrect transport device; inappropriate specimen transport conditions; specimen received after prolonged delay in transport (usually more than 72 hours); specimen stored or transported at room temperature; wooden shaft swab in transport device; unlabeled specimen or name discrepancy between specimen and request label
