| Turnaround Time: 3 weeks | Reference Range: Nonreactive |
| Limitations: May not detect a recent infection, or infection in a person with a severely compromised immune system. | Interpretation: Nonreactive indicates that the patient does not have detectable antibody to the infectious agent. Reactive indicates that the patient has detectable antibody to the infectious agent, and depending on the clinical picture, may have a current or past infection. |

Parainfluenza (Culture – Isolation)
< Return to Table of Contents
| Test Includes: Cell culture | |
|
Reporting |
|
| Results Available: 5-14 days | Contact #s: 512-458-7594 |
|
Reference |
|
| Method: Cell Culture | |
| Turnaround Time: 5-14 days | Reference Range: No virus isolated |
| Limitations: | Interpretation: A result of “No virus isolated” does not necessarily mean absence of a viral agent. The success of virus isolation depends a great deal on the submission of the proper specimen, collected at the right time, adequately maintained, and shipped with the least possible delay. |
|
Specimen Requirements |
|
| Specimen Collection: Specimens should be collected at an appropriate anatomic site and at the proper time after infection because viruses are generally shed for only a short period of time. Refer to Specimen Collection by Type table for additional instructions. | Sample Type: See preferred specimen. |
| Volume/Amount Required: Swabs in 2-4 mLs of viral transport media. | Preferred Specimen: Throat Swab; Nasopharyngeal Secretions |
| Collection/Preservation: Viral transport media. | Storage Instructions: Arriving < 48 hours after collection, store and send at 2-8° C. Arriving > 48 hours after collection, store and send at -70° C (dry ice). |
| Causes for Rejection: Specimens submitted on a preservative such as formalin. | Sample Container: Sterile container |
| Sample Test Kit: | Availability: Monday - Friday |
| Diagnostic Information: Specimens are inoculated onto a variety of cell culture monolayers. If characteristic CPE or hemadsorption is observed, confirmation of identification will be performed. | |
