Diagnostic accuracy and reliability of the Toshiba rapid influenza diagnostic kit compared to the quickNavi diagnostic kit and polymerase chain reaction (PCR) test

INTERVENTION: Analysis of Toshiba's rapid diagnosis of nasal or throat swabs to detect Influenza virus A or B by new point of care testing (POCT) device using optical attenuation caused by reflection or scattering at formed immune complexes, the accuracy of results will be compared with an existing rapid influenza POCT device. Diagnosis of influenza will only be made from the sample analysed by the Australian accepted standard RT‐PCR test. Participants will provide 3 samples in total at the one visit from either nose or throat. One for each of the devices and one for the RT‐PCR test Participants will be asked about the onset of their influenza symptoms and what those symptoms are and have their temperature taken. CONDITION: influenza PRIMARY OUTCOME: Diagnostic testing of nasal and throat sampling on Toshiba's scanning system compared to the QuickNavi existing rapid point of care test (POCT) device to determine the accuracy of Toshiba's POCT against and existing POCT. SECONDARY OUTCOME: Compare both POCT devices for accuracy of nasal and throat sampling results for influenza against the PCR test INCLUSION CRITERIA: Consenting adults or children (parent, guardian, or legal representative providing consent) presenting with influenza symptoms in whom there is a physician assessment of suspected influenza.
