Covid-19 Rapid Antigen Detection Kit (GICA)
Theory of the Test
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.

Interpret Result
Positive Result: If you see two lines, Both the control line (C) and test line (T) appear. This means that SARS-CoV-2 antigen was detected. NOTE: Any faint line in the test line region (T) should be considered positive.
Negative Result: If you see only the Control (C) line is present,and no test(T) line present, this means that SARS-CoV-2 antigen was not detected.
Invalid Result: Find the result window. If Control line (C) fails to appear, the test did not work and is considered Invalid
