The GOLDEN TIME COVID-19 (SARS-CoV-2) Antigen Rapid Test Kit represents a significant advancement in diagnostic technology, offering a reliable and efficient solution for detecting the novel coronavirus. This article delves into the product's functionality, advantages, technical specifications, applications, and the background of its manufacturer, Gaobeidian PRISES Biotechnology Co., Ltd.

How the Test Kit Works

The GOLDEN TIME Antigen Test Kit employs immunochromatography, a widely used method in rapid diagnostic tests. The test strip consists of 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.

Key Features and Advantages

The GOLDEN TIME Antigen Test Kit is designed to provide rapid, accurate, and user-friendly results. Here are its standout features:

• Easier: No special equipment is required. The test is straightforward and does not necessitate complex procedures.
• Rapid: Results are available in just 10 minutes, making it ideal for on-site testing.
• Accurate: The kit's clinical sensitivity (96.33%) and specificity (99.56%) have been validated through PCR and clinical diagnosis.
• Diversity: It works with multiple specimen types, including nasal swabs, oropharyngeal swabs, and nasopharyngeal swabs.
