CDC Interim Guidance on Specimen Collection & Testing for Avian Influenza

Avian Influenza Testing for suspect cases of highly pathogenic avian influenza (H5N1) or influenza A (H7N9) is available from the MSPHL only if indicated after a case investigation has been initiated. Refer to the Department of Health and Senior Service's (DHSS) Pandemic Influenza website, for instructions and to report any suspect case of avian influenza to DHSS. Note: primary point of contact is the Bureau of Communicable Disease Control and Prevention (573-751-6113 or 800-392-0272).

Consultation with the Bureau of Communicable Disease Control and Prevention (573-751-6113 or 800-392-0272) is required prior to collecting clinical specimens.

Kits for the submission of avian influenza A (H5N1) and avian influenza A (H7N9) specimens are certified for the transportation of infectious substances. These kits will be provided only after consultation with the Healthcare Associated Infections Coordinator.

Nasopharyngeal Swab
Nasal Swab / Oropharyngeal Swab combination
Conjunctival Swab
Nasopharyngeal Swab / Oropharyngeal Swab combination
Nasal Aspirate or Wash Endotrachial Aspirate 
Bronchoalveolar Lavage

Autopsy specimens that are acceptable: Fresh-frozen, unfixed lung tissue

See Avian Flu Information link above for further information on additional autopsy and blood specimens that can be sent to CDC for testing.

Because the sensitivity of commercially available rapid diagnostic tests for influenza may not always be optimal, RT-PCR testing may be performed even if influenza rapid diagnostic testing is negative on patients meeting the clinical criteria for avian influenza infection.

Requests for avian influenza collection kits should be directed to the Missouri State Public Health Laboratory at 573-751-3334. Instructions for specimen collection and transport may be found in the “Instructions for Submitting Avian Influenza Specimens to the State Public Health Laboratory” (see link below).

Refer to the CDC infection control precautions when collecting and handling laboratory specimens.
