Study Overview
=================
Brief Summary
-----------------
The primary purpose of this study is to validate the sensitivity and specificity of the iTreat Flu A+B Test and the ellume.lab Flu A+B Test in detecting influenza A and influenza B as compared to viral culture. The secondary aims are to: Validate the sensitivity and specificity of the iTreat Flu A+B Test and the ellume.lab Flu A+B Test in detecting influenza A and influenza B as compared to Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). Evaluate the correct interpretation of the iTreat Flu A+B Test by subjects with influenza-like symptoms. Evaluate the subjects' satisfaction with the convenience, comfort and ease of use of the iTreat Flu A+B Test. Evaluate the operators' satisfaction with the ease of use of the ellume.lab Flu A+B Test.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: iTreat Flu A+B Test and ellume.lab Flu A+B Test<br>Upper respiratory tract samples from participants will be tested with: iTreat Flu A+B Test; ellume.lab Flu A+B Test; Reverse Transcriptase Polymerase Chain Reaction (RT-PCR); and viral culture. | Diagnostic Test: iTreat Flu A+B Test<br>* The iTreat Flu A+B Test is a rapid in vitro diagnostic test for the detection of influenza A or influenza B in nasal swab samples. The iTreat Flu A+B Test is designed to be simple to use and generates a result within 15 minutes.<br>Diagnostic Test: ellume.lab Flu A+B Test<br>* The ellume.lab Flu A+B Test is an in vitro diagnostic test intended to be used at point-of-care for the detection of influenza A or influenza B in nasal swab samples. The ellume.lab Flu A+B Test generates a result within 10 minutes.<br>Diagnostic Test: Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)<br>* Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) is a molecular diagnostic technique for the detection and identification of influenza viruses, both for clinical samples and isolates. The reverse transcriptase polymerase chain reaction (RT-PCR) allows template viral RNA to be reverse transcribed producing complementary DNA (cDNA) which can then be amplified and detected.<br>Diagnostic Test: Viral culture<br>* Nasopharyngeal samples will be inoculated into appropriate culture media for influenza viral culture. In this test, the virus is actually grown and further identified in the laboratory as influenza A or B.<br>|
