The QuickVue Dipstick Strep A test allows for the rapid qualitative detection of Group A Streptococcal antigen directly from patient throat swab specimens, or confirmation of presumptive Group A Streptococcal colonies recovered from culture. The test is intended for use as an aid in the diagnosis of Group A Streptococcal infection. The QuickVue Dipstick Strep A test is a lateral flow immunoassay utilizing Quidel's patented antibody-labeled particles (within 5 minutes). The test detects either viable or nonviable organisms directly from throat swabs or culture colonies.
