POCT Respiratory Syncytial Virus antigen
|Performed by||Authorized Point of Care testing site staff|
|In House Availability||During clinic hours|
|Collection Instructions||Nasopharyngeal Swabs:
Polyester, rayon, foam or cotton swabs, all with flexible shafts, may be used to collect the specimen. Add swab specimens to 0.5-3.0 ml of saline immediately after collection, rolling swab in the solution to elute sample.
Collect nasal wash samples in standard collection cups. Use procedures appropriate for the age of the patient. Nasal washes do not need additional preparation.
|Sample type||Nasal swab or nasal wash|
|Stability||Samples should be tested as soon as possible after collection.|
|Additional information||A negative test result does not exclude infection with RSV nor is it intended to rule out other microbial-caused respiratory infections.
The Binax RSV test detects viable and non-viable RSV. Test performance depends on antigen load in the specimen and may not correlate with cell culture performed on the same specimen.
Inadequate specimen collection or low levels of virus shedding may result in sub-optimal performance and may yield false negative results.
Binax test performance has not been evaluated in patients who have been treated with palivisumab. However, an analytical study has demonstrated that palivisumab interferes with the ability of the Binax RSV Test to detect RSV.
The potential for interference from anti-microbials and interferon has not been established.
Monoclonal antibodies may not detect all antigenic variants or new strains of RSV.
|LDT or Mod FDA?||No|
