Rapid influenza diagnostic test

A rapid influenza diagnostic test (RIDT) tells whether a person has a current influenza infection by detecting the <a href="/en/Influenza" title="Influenza" class="wl">influenza</a> viral <a href="/en/Nucleoprotein" title="Nucleoprotein" class="wl">nucleoprotein</a> <a href="/en/Antigen" title="Antigen" class="wl">antigen</a>. Commercially available RIDTs can provide results within 30 minutes. These results can be observed by a color change or other visual signals.<a href="#cite_note-1" style="counter-reset: mw-Ref 1;">[1]</a><a href="#cite_note-2" style="counter-reset: mw-Ref 2;">[2]</a> For clinicians, RIDTs serve as a first-line test that can be confirmed (especially if negative) by traditional diagnostic tests. RIDTs also allow clinicians to promptly start antiviral treatment in high-risk populations, to formulate effective infection control measures, and to make informed decisions regarding diagnostic investigations.<a href="#cite_note-3" style="counter-reset: mw-Ref 3;">[3]</a><a href="#cite_note-4" style="counter-reset: mw-Ref 4;">[4]</a> RIDTs have been shown to reduce chest radiography and blood tests in ambulatory care settings, but not antibiotic prescribing, or time in the emergency department.<a href="#cite_note-5" style="counter-reset: mw-Ref 5;">[5]</a>

Accordung to a study, an H1N1 rapid test had a sensitivity of 66&nbsp;%, corresponding to a false-negative probability of 34&nbsp;% in detecting H1N1.<a href="#cite_note-pmid20409373-6" style="counter-reset: mw-Ref 6;">[6]</a>

A rapid influenza diagnostic test tells whether a person has a current influenza infection by detecting the influenza viral nucleoprotein antigen. Commercially available RIDTs can provide results within 30 minutes. These results can be observed by a color change or other visual signals. Accordung to a study, an H1N1 rapid test had a sensitivity of 66 %, corresponding to a false-negative probability of 34 % in detecting H1N1.
