Introduction

The GOLDEN TIME COVID-19 (SARS-CoV-2) Antigen Test Kit represents a critical advancement in rapid diagnostic technology, offering a user-friendly and efficient method for detecting the presence of the SARS-CoV-2 virus. This test kit leverages immunochromatography technology, a widely recognized method for point-of-care diagnostics. By providing results within 10 minutes, it enables timely decision-making for healthcare providers and individuals alike. The product is designed to meet the urgent need for fast, accurate, and accessible testing in the context of the global pandemic.

Functionality and Technology

The GOLDEN TIME antigen test kit operates on the principle of immunochromatography, a technique that utilizes colloidal gold as a detection label. This method is known for its simplicity, speed, and reliability. The test strip consists of 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) and a control line (C line). The T line is pre-coated with antibodies for detecting the novel coronavirus nucleoprotein, while the C line ensures the test is functioning correctly.

When a nasal swab, oropharyngeal swab, or nasopharyngeal swab is collected and processed with the provided reagents, the test detects the presence of SARS-CoV-2 antigens. The colloidal gold-labeled antibodies bind to the viral antigens, creating a visible color change on the test strip. This visual interpretation eliminates the need for specialized equipment, making it ideal for use in diverse settings.

Technical Specifications

Components and Packaging

The GOLDEN TIME test kit includes the following components:

• Individually Sealed Foil Pouches containing:
  • One device with a recombined pad (novel coronavirus monoclonal antibody and rabbit IgG antibody), T line (novel coronavirus monoclonal antibody), and C line (goat-anti-rabbit IgG antibody).
  • A desiccant to maintain product stability.
• Sample Tubes (20): Each containing 0.3ml of sample buffer.
• Nasopharyngeal Swabs (20): For specimen collection.
• Quick Reference Instructions (1): A guide for proper test execution.

The kit is available in 1, 5, or 20 tests per carton, with customization options to meet specific customer needs.

Storage and Stability

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

Applications and Use Cases

The GOLDEN TIME antigen test kit is designed for in vitro qualitative detection of SARS-CoV-2 antigens in human nasopharyngeal swabs. Its applications include:

• Point-of-Care Testing (POCT): Ideal for use in clinics, hospitals, and community health centers where rapid results are critical.
• Screening Programs: Facilitates large-scale screening in workplaces, schools, and public events to identify potential cases quickly.
• Travel and Quarantine Requirements: Provides a reliable solution for travelers and individuals in quarantine to confirm their infection status.
• Home Use: The user-friendly design allows for self-testing in home settings, though professional interpretation is recommended.

While the test provides a preliminary result, it is essential to correlate findings with clinical judgment and other diagnostic methods such as PCR for confirmation, as emphasized by the National Institute of Standards and Technology (NIST) in its guidelines for diagnostic testing accuracy [1].
