Influenza A/B Ag
1 FLOCKED NPH swab or Nasal Washings
Culturette or Specimen container
1 NPH Swab. Send swab in culturette. We recommend a second NPH swab in M4 viral transport medium in case follow-up testing may be required. Alternate specimen: Nasal wash: 1.5 mL wash in sterile container
Cause for rejection:
Specimen dry, non- sterile container or incorrect swab (do not use NPH wire swab), QNS.
NPH swab in culturette or Nasal wash used for Rapid Influenza test. Testing no longer automatically reflexes to Respiratory Virus Isolation (RVI). A second NPH flocked swab, broken off in M4 must be submitted along with a separate order for RVI requests.
RVI's are not performed on specimens that are positive by the Rapid Influenza Ag Test. A negative result does not rule out viral infection. Positive results will be called.
