Study type
Description of intervention(s) / exposure
Adults who present to a general practitioner with an influenza-like illness and are swabbed for surveillance purposes are given the opportunity the participate in this study if they have an Android or iOS smartphone or tablet. The patient will take the self-test home. The test consists of the QuickVue test for influenza A and B, and the flu@home app. The QuickVue test is a lateral flow test. It requires the patient to take a nasal swab and elute the swab into the test tube with the reagents provided, and put a test strip into the test tube. If positive, a pink line will appear on the test strip. All instructions for performing the test are guided by the app. The app will also ask the patient to answer questions about symptom history and risk factors, and also ask the patient to take a photo of the test strip once completed. This, combined with the QuickVue test, will give them an accurate result in approximately 20 minutes, via the app. This result will be compared to the gold-standard PCR result (from surveillance data), the results of which are provided to their GP within 24 hours of receipt of the sample at the lab.

The app data are matched up to the PCR data via a unique barcode identification number. For the first 4 weeks of the study these data are continually analysed by the flu@home team and used to develop an optimal algorithm which incorporates the PCR data, photograph, and patient survey data to provide the patient with a highly accurate result.

Diagnosis / Prognosis
Comparator / control treatment
PCR test is the gold-standard test. ALL patients will undergo PCR test, as well as the flu@home test. The PCR is undertaken by the GP for surveillance purposes as part of the Australian Sentinel Practices Research Network (ASPREN), The GP performs a nasopharyngeal, deep nasal or throat swab on the patient. The sample is sent to SA Pathology via Australia Post.
Control group

Primary outcome [1] 320741 0
Diagnosis of influenza from the flu@home test.
Timepoint [1] 320741 0
The test itself takes approximately 15 minutes to perform. Patients must complete the test within 7 days of symptom onset.
Secondary outcome [1] 372706 0
Comparison of flu@home result to the gold-standard PCR test via sensitivity / specificity analysis.
Timepoint [1] 372706 0
We will receive the PCR result approximately 1 week after the GP consultation. Results will be matched via a unique 8 digit number.

Brief summary
The overall aim of the Australian arm of the Seattle Flu Study is to evaluate the accuracy of the flu@home self-test for influenza by recruiting patients who present with an influenza-like illness to a GP or nurse practitioner who is a member of ASPREN for national influenza surveillance activities. Flu@home test results will be compared to PCR test results, which is considered to be the gold-standard for detection of influenza.
