In the ongoing battle against the COVID-19 pandemic, rapid and reliable diagnostic tools have become essential. The GOLDEN TIME COVID-19 (SARS-CoV-2) Antigen Test Kit stands out as a critical solution for quick, on-site detection of the virus. This article delves into the product's functionality, technical specifications, applications, and the company behind it, while emphasizing its role in public health and safety.

Understanding the Technology: Immunochromatography

The GOLDEN TIME Antigen Test Kit employs immunochromatography, a widely used method in rapid diagnostic tests. This technique involves the use of colloidal gold as a detection label, which binds to specific antibodies to produce a visible result. The test strip is composed of two key components: a conjugate pad and a nitrocellulose membrane strip. The conjugate pad contains mouse anti-novel coronavirus nucleoprotein monoclonal antibodies conjugated with colloidal gold, while the 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 nucleoprotein of SARS-CoV-2, and the C line ensures the test's validity by reacting to the conjugate pad's components.

Key Features of the GOLDEN TIME Antigen Test Kit

The GOLDEN TIME Antigen Test Kit is designed to meet the demands of modern healthcare with its ease of use, speed, and accuracy. Below are its core features:

• Easier: No specialized equipment is required. The test is simple to administer, with intuitive visual interpretation of results.
• Rapid: Results are available in just 10 minutes, enabling timely decision-making.
• Accurate: The test has been validated using PCR and clinical diagnosis, ensuring high reliability.
• Diverse: It works with oropharyngeal, nasal, or nasopharyngeal swabs, providing flexibility in sample collection.

Components and Usage

The kit includes the following components:

• Individually sealed foil pouches containing:
• a. One device with:
• 1) Novel coronavirus monoclonal antibody and rabbit IgG antibody for the recombined pad
• 2) Novel coronavirus monoclonal antibody for the T line
• 3) Goat-anti-rabbit IgG antibody for the C line
• b. One desiccant
• Sample Tubes (20): Sample buffer (0.3 ml/bottle)
• Nasopharyngeal Swabs (20)
• Quick Reference Instructions (1)

The test is straightforward to use. After collecting a sample, the user adds it to the sample buffer, applies the mixture to the test strip, and waits for the results. The T line indicates a positive result, while the C line confirms the test's validity.

Storage and Stability

To ensure optimal performance, the test should be stored at 2℃–30℃ in a dry place, away from direct sunlight. It should not be frozen. The shelf life is 24 months from the manufacturing date. Once the foil pouch 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 suitable for a variety of applications, including:

• Point-of-Care Testing: Ideal for use in clinics, pharmacies, and remote areas where access to advanced laboratories is limited.
• Screening Programs: Facilitates large-scale screening in schools, workplaces, and public events to identify potential cases quickly.
• Home Use: Provides individuals with a reliable way to monitor their health status without visiting a healthcare facility.
• Travel and Quarantine: Helps travelers and quarantined individuals confirm their infection status before and after journeys.

According to the National Institute of Standards and Technology (NIST), rapid antigen tests like this one play a crucial role in public health surveillance and epidemic control (NIST, 2025). These tests complement PCR testing by offering a faster alternative, especially in resource-limited settings.
