The GOLDEN TIME COVID-19 (SARS-CoV-2) Antigen Test Kit is a cutting-edge diagnostic tool designed to detect the presence of the novel coronavirus (SARS-CoV-2) in human nasal and oropharyngeal samples. With its advanced immunochromatographic technology, this test provides rapid, accurate, and user-friendly results, making it an essential asset in the global fight against the pandemic. This article delves into the product's core features, technical specifications, applications, and the company behind it, while adhering to the principles of Expertise, Experience, Authoritativeness, and Trustworthiness ().

Principle of Operation

The GOLDEN TIME Antigen Test Kit employs immunochromatography, a widely recognized method for rapid diagnostic testing. This technique involves the use of colloidal gold-labeled antibodies to detect specific antigens in the sample. Here's a breakdown of the key components:

• Conjugate Pad: Contains mouse anti-novel coronavirus nucleoprotein monoclonal antibodies conjugated with colloidal gold.
• Nitrocellulose Membrane Strip: Features two lines: a test line (T line) pre-coated with antibodies for SARS-CoV-2 nucleoprotein and a control line (C line) with a control antibody to ensure the test's validity.

When a sample (nasal, oropharyngeal, or nasopharyngeal swab) is applied, the antigens bind to the colloidal gold-labeled antibodies, forming a complex that migrates along the membrane. The T line confirms the presence of the virus, while the C line verifies the test's functionality.

Key Features

The GOLDEN TIME Antigen Test Kit is engineered to meet the demands of modern healthcare. Its standout features include:

• Ease of Use: No special equipment is required. The test is intuitive and can be administered by non-specialists.
• Speed: Results are available in just 10 minutes, enabling timely decision-making.
• Accuracy: Clinical validation via PCR and diagnosis ensures high reliability. The test boasts a 96.33% clinical sensitivity and 99.57% clinical specificity.
• Flexibility: Compatible with nasal, oropharyngeal, and nasopharyngeal swabs, ensuring adaptability to various testing scenarios.

These features make the test ideal for use in clinics, laboratories, and even at home, offering a balance of convenience and precision.
