Rotavirus Rapid Test- Rotavirus Antigen Rapid Test | 818-591-3030


Medical tests conducted on the efficiency of the Rotavirus Rapid Test have shown that the Rotavirus Rapid Test is equally as accurate as the Rotavirus ELISA test available on the market today.  The test results revealed that the Rotavirus Rapid Test was just as sensitive as the direct electron microscopy of the Rotavirus ELISA test.   The Rapid Rotavirus Antigen Test has shown 98% sensitivity and 97% specificity compared to the Rotavirus ELISA test results.  Thus, the studies concluded that the Rotavirus Rapid Test is an accurate and rapid qualitative method for the detection of rotavirus in stools of symptomatic children.


Of course, Rotavirus ELISA kits are highly effective due to their reproductibility, easy interpretation, and their allowing simultaneous performance of several tests at one time.  For a number of years, Rotavirus ELISA Kits have been an important technique for the diagnosis of rotavirus infection.  Although particularly suited for testing large numbers of clinical specimens, Rotavirus ELISA tests often required several hours to complete, and their complexity limited their use to larger laboratories.  The ease of performance and time to completion clearly favored the Rotavirus Rapid Test.  The studies concluded that the Rotavirus Rapid test is particularly suited not only for major laboratories but also for physicians’ offices, clinics, and field work in rural or tropical settings.


Diagnostic Automation/Cortez Diagnostics, Inc. offers a one-step Rotavirus Rapid Test that is an in vitro qualitative immunocromatographic assay for the rapid detection of rotavirus antigens in human stool specimen.  The Rotavirus Rapid Test results are intended to aid in the diagnosis of rotavirus infection and to monitor the effectiveness of therapeutic treatment. This Rotavirus Rapid Test is for in vitro diagnostic use only.


To perform the Rotavirus rapid test, an aliquot of diluted stool sample is added to the sample well of the Rotavirus rapid test cassette.  The sample on the Rotavirus Rapid Test flows through a label pad containing rotavirus antibody coupled to red-colored colloidal gold.  If the sample on the Rotavirus rapid test contains rotavirus antigens, the antigen will bind to the antibody coated on the colloidal gold particles to form antigen-antibody-gold complexes. These complexes move on the nitrocellulose membrane by capillary action toward the Rotavirus rapid test line region on which rotavirus specific antibodies are immobilized.  As the complexes reach the Rotavirus rapid test line, they will bind to the antibody on the membrane in the form of a line. A second red control line will always appear in the Rotavirus rapid test result window to indicate that the Rotavirus rapid test has been correctly performed and the Rotavirus rapid test device functions properly.  If rotavirus antigen is not present or lower than the detection limit of the Rotavirus rapid test, only the control line will be visible.  If the control line does not develop, the Rotavirus rapid test is invalid.


Overall, with its proven high sensitivity and specificity, Diagnostic Automation/Cortez Diagnostics, Inc.’s OneStep Rotavirus Antigen RapiCardTM InstaTest is highly effective, inexpensive, and simple to use. Expected values for any given population should be determined for each laboratory. The positivity rate of any given laboratory may vary depending on geographic location, season, and living environment.  The Rotavirus Rapid Test is available in cassette format only.  Each Rotavirus rapid test cassette contains a test strip with rotavirus specific antibody on the Rotavirus rapid test region of the membrane and colored rotavirus antibody-gold conjugate pad.  For more information about this Rotavirus Rapid Test, or on our Rotavirus ELISA Kits, please contact our Customer Service Department.
