The GOLDEN TIME COVID-19 (SARS-CoV-2) Antigen Test Kit is a rapid diagnostic tool designed for the in vitro qualitative detection of SARS-CoV-2 antigens in human nasal, oropharyngeal, or nasopharyngeal swabs. This test provides preliminary results within 10 minutes, offering a reliable solution for early detection and containment of the virus. Developed by Gaobeidian PRISES Biotechnology Co., Ltd, the kit combines advanced immunochromatography technology with high clinical accuracy, making it a trusted choice for healthcare professionals and individuals alike.

Product Overview

The rapid antigen test kit for COVID-19 utilizes colloidal gold-based immunochromatography, a widely recognized method for its simplicity and speed. The test strip is composed of a burgundy-colored conjugate pad containing mouse anti-novel coronavirus nucleoprotein monoclonal antibodies conjugated with colloidal gold. This is paired with a nitrocellulose membrane featuring 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. The kit is designed to deliver 96.33% clinical sensitivity and 99.57% clinical specificity, with an overall agreement of 98.79% compared to PCR testing. These metrics highlight its reliability in clinical settings.

Key Features

• Easier: No special equipment required. The test is user-friendly and allows for intuitive visual interpretation.
• Rapid: Results are available in 10 minutes, enabling quick decision-making.
• Accurate: Validated by PCR testing and clinical diagnosis, ensuring high reliability.
• Diverse: Compatible with oropharyngeal swabs, nasal swabs, and nasopharyngeal swabs, offering flexibility in sample collection.
