How Does It Work?
Antigen testing is used for testing different viruses and pathogens. The viral antigen testing employs the sandwich immunocapture method to determine the presence of SARS-CoV-2 antigen.
Specificity of a test kit refers to the ability of a test for correct identification of patient without disease. The SARS-CoV-2 Antigen Test Kit (Colloidal Gold) had a negative percent agreement of 99.5% (95%CI: 98.6%~99.7%).
Sensitivity, often treated as accuracy, is the test’s ability for correct identification of patients having a disease. The SARS-CoV-2 Antigen Test Kit (Colloidal Gold) had a positive percent agreement of 96.8% (95%CI: 92.8%~98.6%) with specimens of a Ct count ≤33, 92.2% (95%CI: 87.8%~ 95.2%)) with specimens of a Ct count ≤37.
Unlike NAATs and PCR, you don’t have to wait for 1-3 days. It only takes 15-30 minutes for an antigen test to give you the results.
The accuracy, and sensitivity values of the Colloidal gold antigen test are high and trustable.
How To Store?
The shelf life of the test kit is valid for 18 months, and it should be stored at 2 -30oC in a dry place.
