Respiratory rapid tests for clinics and laboratories

First Diagnostic™ Corporation supplies respiratory rapid tests for professional in vitro diagnostic use. The range centers on one product, the ATFirst™ Flu A & B test, which detects influenza A and B nucleoprotein antigens and distinguishes type A from type B.

Lateral flow tests of this kind are used in outpatient and emergency departments, primary care clinics and hospital laboratories during the influenza season. Each result is an aid to diagnosis and must be interpreted by a clinician with other clinical and laboratory findings.

Using influenza antigen results responsibly

  • A negative result does not exclude infection with influenza A or B; results are used together with clinical findings.
  • The test distinguishes influenza A from B but does not identify subtypes or strains.
  • It detects both viable and non-viable virus, and its performance has not been established for monitoring antiviral treatment.
  • Predictive values depend on how much influenza is circulating.
  • A nasally administered influenza A vaccine may produce a positive result for up to three days after vaccination.
