PBF Vstrip COVID-19 Antigen Rapid Test is a rapid immunochromatographic assay that utilizes specific antibodies to detect nucleocapsid protein of SARS-CoV-2 virus in nasopharyngeal swab specimens.
The Vstrip COVID-19 Antigen Rapid Test is designed to detect antigen from the SARS-CoV-2 in nasopharyngeal swab from patients who are suspected of COVID-19 by their healthcare provider.
To perform the test, insert the test dipstick into the extraction buffer. If the extracted specimen contains SARS-CoV-2 viral antigen, a red test line will appear on the dipstick indicating a positive result and along with a purple black control line.
A purple black control line will always appear in the result window to indicate that it confirms correct assay procedure and active kit components.
If SARS-CoV-2 viral antigen is not present, or is present at very low levels in the specimen, only the control line will be visible.
Whenever the purple black control line does not develop within 10 minutes, the test is considered invalid. – Read IFU for more information.
