- Directigen Influenza
- Influenza A Direct Assay
Enzyme immunoassay for influenza type A.
Confirm the diagnosis of influenza type A infection
Presentation of influenza infection ranges from mild respiratory illness to fatal pneumonia. In addition, secondary bacterial infection can be a serious complication. People at highest risk from infection include the elderly and patients with underlying health problems. Individuals residing in institutional settings, such as nursing homes or college dormitories, may also be at increased risk. This rapid test may be useful in early documentation of influenza A in a community not known to have flu activity during the current season. This can allow for rapid implementation of appropriate control and/or prophylactic measures.
Nasopharyngeal (NP) swab in viral transport medium or NP wash or aspirate
2-3 mL NP wash, 0.5 mL NP aspirate dispersed in at least 2-3 mL transport medium or saline, or swab
Viral, Chlamydia, or Mycoplasma culture transport provided by LabCorp, or other appropriate transport medium; sterile leakproof container
Causes for Rejection
Bacterial swab specimen; specimen received in grossly leaking transport container; dry specimen; specimen submitted in fixative or additive; specimen received in expired transport media or incorrect transport device; inappropriate specimen transport conditions; specimen received after prolonged delay in transport (usually more than 72 hours); specimen stored or transported at room temperature; wooden shaft swab in transport device; unlabeled specimen or name discrepancy between specimen and request label
Submit one specimen per test requested. Specify the exact specimen source/origin (eg, genital lesion). Indicate a specific test number on the request form. Check expiration date of transport; do not use expired devices.
