COVID-19 Antigen Rapid Test Principle

The coronavirus antigen rapid test kit is a lateral flow assay that qualitatively detects the presence of nucleocapsid (N) protein in upper respiratory samples (nasal swabs). This lateral flow assay is designed with the sandwich immunoassay format. When the specimen is added onto the sample pad of a test cassette, coronavirus N protein binds with colloidal gold-labeled SARS-CoV-2 N protein antibody to form an antibody-antigen (Ab-Ag) complex. The Ab-Ag complex is captured by SARS-CoV-2 N protein antibody (Rabbit monoclonal antibody) when migrating to the test line under capillary action. A red-colored band will appear on the test line, which indicates the specimen is COVID-19 nucleocapsid protein positive. No color band will appear on the test line if the specimen does not contain any coronavirus antigen (N protein), or the antigen level is below detection limit.

Advantages of Antigen Rapid Test

Although the development cycle of antigen detection is relatively long, its
1. Sensitivity and specificity are higher than antibody detection
2. The pathogen can be detected at the initial stage of infection
3. Short TAT and simple operation.
4. No professional technicians and equipment are required, and the test can be completed in 15 min.
5. Home use.
6. Personal test.
