Developed by Gaobeidian PRISES Biotechnology Co., Ltd, the COVID-19 (SARS-CoV-2) Antigen Test Kit represents a critical advancement in rapid diagnostic solutions. This article provides an in-depth exploration of its functionality, technical specifications, applications, and the company's commitment to innovation. For authoritative validation of diagnostic standards, refer to the National Institute of Standards and Technology (NIST), which establishes benchmarks for medical testing accuracy.

Principle of Operation

The COVID-19 (SARS-CoV-2) Antigen Test Kit employs immunochromatography, a technique that leverages antigen-antibody interactions for rapid detection. The test strip comprises three key components:

• Burgundy-colored conjugate pad: Contains mouse anti-novel coronavirus nucleoprotein monoclonal antibodies conjugated with colloidal gold.
• Nitrocellulose membrane strip: Features a test line (T line) pre-coated with antibodies for detecting the nucleoprotein of SARS-CoV-2 and a control line (C line) for validating the test's integrity.

This method ensures visual detection of the antigen within 10 minutes, offering a balance of speed and reliability. The and illustrate the kit's design and operational components.
