Introduction

The COVID-19 (SARS-CoV-2) Antigen Test Kit represents a critical advancement in rapid diagnostic solutions, designed to detect the presence of the novel coronavirus (SARS-CoV-2) in human nasal and oropharyngeal swabs. Developed by Gaobeidian PRISES Biotechnology Co., Ltd, this test combines speed, accuracy, and ease of use to support public health efforts. This article provides an in-depth analysis of the product's features, technical specifications, applications, and the company's commitment to innovation.

Principle of Operation

The COVID-19 Antigen Test Kit employs immunochromatography, a widely used method for rapid diagnostics. The test strip comprises two key components: a burgundy-colored conjugate pad containing mouse anti-novel coronavirus nucleoprotein monoclonal antibodies conjugated with colloidal gold, and a nitrocellulose membrane strip with a test line (T line) and a control line (C line). The T line is pre-coated with antibodies for detecting the nucleoprotein of SARS-CoV-2, while the C line ensures the test's validity by reacting to the conjugate pad's antibodies.

This technology enables the detection of viral antigens within minutes, offering a reliable alternative to traditional PCR-based methods. The colloidal gold labeling enhances visibility, allowing for intuitive visual interpretation of results.

Key Features

• Easier: No special equipment is required, making it accessible for both professionals and laypersons.
• Rapid: Results are available in just 10 minutes, minimizing waiting times.
• Accurate: Validated by PCR and clinical diagnosis, ensuring high reliability.
• Diverse: Compatible with oropharyngeal, nasal, and nasopharyngeal swabs, offering flexibility in sample collection.

Product Components

The test kit includes the following components:

• Individually sealed foil pouches containing:
• One test device with a conjugate pad, T line, and C line.
• Desiccant to maintain stability.
• Sample Tubes (20): Each with 0.3ml of sample buffer.
• Nasopharyngeal Swabs (20): For sample collection.
• Quick Reference Instructions (1): Detailed guidelines for use.

Technical Specifications

Storage and Stability

The test kit should be stored at temperatures between 2°C and 30°C in a dry place, away from direct sunlight. Freezing is not recommended. The shelf life is 24 months from the manufacturing date. Once the aluminum foil bag is opened, the test card must be used within one hour to ensure accuracy.

Applications and Use Cases

The SARS-CoV-2 Antigen Test Kit is designed for in vitro qualitative detection of the novel coronavirus in human nasopharyngeal swabs. It serves as a preliminary diagnostic tool to aid in identifying infections. However, results must be interpreted alongside clinical findings and professional medical judgment. For confirmation, alternative tests such as PCR are recommended.

This product is ideal for use in healthcare facilities, airports, schools, and workplaces, where rapid screening is critical. Its portability and ease of use make it suitable for point-of-care testing and mass screening programs.
