Covid-19 Rapid Antigen Test Kit

Product Information:

Coronaviruses are a large family of viruses which may cause illness in animals or humans. SARS-CoV-2 is an enveloped, single-stranded RNA virus of the β genus. The virus can cause mild to severe respiratory illness and has spread globally. The SARS-CoV-2 Antigen Test Kit (GICA) for home use is a rapid lateral flow immunoassay for the qualitative detection of SARS-CoV-2 directly from nasal (anterior) swab, without viral

transport media. The Kit contains all components required to carry out an assay for SARS-CoV-2.

Theory:

The SARS-CoV-2 Antigen Test Kit (GICA) is a colloidal gold enhanced double antibody sandwich immunoassay for the qualitative determination of nucleocapsid (N) protein of SARS-CoV-2 virus in human nasal (anterior) swab.

SARS-CoV-2 antibody is immobilized in the test region on nitrocellulose membrane. If the specimen contains SARS-CoV-2 antigen, during the assay specimen is allowed to react with the colored conjugate (SARS-CoV-2 antibody-colloidal gold conjugate); the mixture then migrates chromatographically on the membrane by the capillary action. An SARS-CoV-2 positive specimen produces a distinct color band in the test region, formed by the specific antibody antigen colored conjugate complex "(Au-SARS-CoV-2-Ab)-(SARS-CoV-2-Ag)- (SARS-CoV-2-Ab)". Absence of this colored band in the test region suggests a negative result. A colored band always appears in the control region serving as procedural control regardless of the specimen contains SARS-CoV-2 or not.
