| SPECIMEN REQUIREMENTS | ||||
|---|---|---|---|---|
| Specimen | Specimen Volume (min) | Specimen Type | Specimen Container | Transport Environment |
| Preferred | See Instructions | Swab | Flocked Flexible Mini-Tip Nasopharyngeal Swab | Refrigerated |
| Alternate 1 | See Instructions | Saline nasal wash | Sterile Screwtop Container | Refrigerated |
| Instructions | Copan's Universal Transport Media (UTM), M4, M5, M6, and Starplex Multitrans are stable up to 72 hours at 2-8 degrees or 25 degrees. Saline nasal washes/aspirates must be refrigerated and tested within 24 hours (or within 4 hours at room temperature). Test sensitivity is optimal with minimally diluted specimens. Therefore, the preferred specimen is a mini-tip nylon flocked swab in 1mL UTM (item 406C from Materials Management). Note: The 1mL UTM provides a concentrated specimen for rapid antigen testing, however, this volume may not be appropriate for some other types of testing. If multiple tests will be ordered from this specimen, please collect additional specimen(s) in 3mL UTM when appropriate. |

| Internal Comments | Removed -H1N1 text: Swine Flu 04/27/09: If the patient is Positive by the rapid influenza A assay, then two nasopharyngeal swabs will be forwarded onto the OK State Health Laboratory for PCR testing. If the patient is Negative by the rapid influenza A assay, RML will hold the swabs for seven days. If the patient is symptomatic and has a recent history of travel to Mexico, Southern Texas or Southern California, then contact RML Microbiology (x15573) to have the two nasopharyngeal swabs forwarded onto the OK State Health Laboratory for molecular testing. If the state finds the specimen positive by PCR, the second swab will be forwarded by the state lab onto CDC for typing. ---------------- 9/21/17 previous spec proc instructions -----JK ----- The preferred specimen is Universal Transport Media (UTM) with mini-Flocked Swab (Comes as a kit: RML Supply# 50775), BD Viral Transport Media (VTM) or M5. Swabs in saline are only acceptable for up to 8 hours. Keep swabs refrigerated (room temperature stability is only 24hrs). For Saline nasal wash: Use bulbous syringe to dispense 2 ml saline into nasal passages. Aspirate at least 1mL back into syringe and transfer to sterile container. Note: Green cap minitip Swab is No Longer Acceptable. Also not acceptable are swabs in M4, M4-RT, Modified or Liquid Stuart’s and Remel M6 transport media. (the green cap minitip swab has liquid stuart’s) Also acceptable is: Mini-tip size applicator Copan eSwab - Green ------------------ 11/16/17 change processing instructions again... removing the information below (MARY HERMAN) -- 11/16/17 11:41:00 AM] Please remove all references to eSwabs from the C A/B flu on RML online. Please edit the recommended specimen type to be UTM- nylon flocked mini-tip swab in UTM. Stability is 72 hours. If you have questions, please consult Brittany V. or Kat H. -----JK ----- Copan's Universal Transport Media (UTM), M4, M5, M6, and Starplex Multitrans are stable up to 72 hours at 2-8 degrees or 25 degrees. Copan eSwab must be refrigerated and tested within 6 hours of collection. Saline nasal washes/aspirates must be refrigerated and tested within 24 hours (or within 4 hours at room temperature). |
