Rapid Diagnostic Test for Influenza

Clinical Validation of the Point-of-Care MSD Influenza Test in Asia

The primary objective of this study is to evaluate the performance of the MSD® Influenza Test in detecting influenza A and influenza B in subjects presenting with influenza-like-illness (ILI).

This is a multicenter, prospective study to evaluate the performance of the MSD Influenza Test for the detection and differentiation of influenza A (including A/H1, A/H3, and A/H5 subtypes) and influenza B. Nasal swabs from subjects presenting at the clinical care facility with ILI will be collected and tested on the MSD Influenza Test. Results from the Test will be compared to results obtained from viral culture performed on a second nasal swab at a reference laboratory.

Inclusion Criteria:

• Any subject (all ages) presenting with ILI (defined as fever [subjective or documented] and cough or sore throat), and suspected of having influenza.
• Subject (parent, guardian, or authorized legal representative) gives informed consent to the study, and provides signed authorization for use and disclosure of protected health information.

Exclusion Criteria:

• Subjects who had prior nasal wash/aspirate or nasopharyngeal wash/aspirate specimens collected for routine health-care purposes within the same suspected influenza infection episode.
• Unable to collect nasal and throat swab.
• Severely ill patient without a family relative to provide informed consent.
