LABORATORY RESOURCES

Laboratory Biosafety:

• Biosafety in Microbiological and Biomedical Laboratories—6th Edition (CDC)

  • See Pages 262, Highly Pathogenic Avian Influenza (HPAI) A Viruses 

  • Note that HPAI A viruses are CDC/USDA select agents! 

    • See BMBL 6 Appendix F for more information: Biosafety in Microbiological and Biomedical Laboratories—6th Edition (CDC)

Community Health Biosafety:

• Extension for Community Healthcare Outcomes Biosafety Program 

Infection Control and Safety When Collecting Specimens and Caring for Patients:  

• Interim Guidance for Infection Control Within Healthcare Settings When Caring for Confirmed Cases, Probable Cases, and Cases Under Investigation for Infection with Novel Influenza A Viruses Associated with Severe Disease (CDC)

CDC Laboratorian Guidance for Specimen Collection and Testing: 

• Interim Guidance on Specimen Collection and Testing for Patients with Suspected Infection with Novel Influenza A Viruses Associated with Severe Disease or with the Potential to Cause Severe Disease in Humans (CDC)

• Influenza Specimen Collection (CDC)

  • Note that CDC recommends collecting a conjunctival swab from patients with conjunctivitis (see here). 

  • Collect both a conjunctival swab and a respiratory specimen (e.g., nasopharyngeal swab) even if the patient doesn’t have respiratory symptoms.   

FDA Influenza IVD Tests with FDA 510(K) Clearance, EUA, or de nova request for Humans:

• List of Influenza Diagnostic Tests

  • Influenza A/H5N1 Specific Detection Test 

  • Influenza A/H7N9 Specific Detection Test 

  • Influenza A/H1/H1pdm09/H3 Seasonal Subtyping Tests 

  • Influenza A Tests (no subtyping)

Information relevant to incidental detection of HPAI on routine influenza IVDs and LDTs 

• Labs are not encouraged to develop or validate specific LDTs for HPAIs at this time. 

• Labs can contact relevant IVD manufacturers for pan-Influenza A primer/probe coverage information on FDA cleared assays.  

• Labs that run LDPs for pan-Influenza A detection can refer to published sequences from recent human and bovine cases for primer/probe coverage:
