The Oregon State Public Health Laboratory will perform virus isolation and PCR typing (to distinguish influenza A and B) and sub‐typing (for H1 and H3) on the following specimens:
1) Specimens submitted by health care providers participating in Oregon’s Outpatient Influenza‐Like Illness Surveillance Network (ILINet).
When completing Form 42 (Virology/Immunology test request form) check off virus isolation and mark "ILI Net" under other. Visit Oregon ILINet for more information.
2) Specimens from patients hospitalized with influenza-like illness in the Portland Tri-county area (Multnomah, Clackamas and Washington counties) as part of a CDC-funded study. We encourage submission of specimens even if rapid influenza tests are negative or have not been performed. However, results of this testing will not be available for 3 days; thus, clinical decision making about treatment or isolation precautions should not be based on these test results.
When completing Form 42 (Virology/Immunology test request form) check off virus isolation and mark "hospitalized" under other. Visit CDC’s Emerging Infections Program for more information.
3) Specimens collected as part of investigations into clusters of respiratory illness in collaboration with Acute and Communicable Disease Program (ACDP) epidemiologists.
When completing Form 42 (Virology/Immunology test request form) check off virus isolation and write in the outbreak number assigned to the outbreak by ACDP in the Outbreak/Study ID box (to report a cluster of respiratory illness, call 971-673-1111).
Visit Respiratory Disease Outbreak Investigation for guidelines on investigating clusters of respiratory illness. For specimens that don’t fall under one of these three categories, please contact OSPHL at 503-693-4100 and ask for “Virus Isolation”.
