A rapid influenza diagnostic test (RIDT) 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 or less.[1]

A study published in The New England Journal of Medicine concludes that that one test generated a false negative 49 percent of the time, meaning it detected H1N1 only 51 percent of the time.[citation needed] Another study published in the Journal of Clinical Virology found another test generated a false negative 82.2 percent of the time, detecting H1N1 only 17.2 percent of the time.[citation needed]

A study in Emerging Infectious Diseases,[2] published by the Centers for Disease Control (CDC), found that a test generated a false negative 88.9 of the time, detecting H1N1 only 11.1 percent of the time.[3][Dead link]
