Quick Test COVID-19 Pre-nasal Test 

Covid-19 Pre-nasal Antigen Test [PRINCIPLE] The COVID-19 Antigen Rapid Test is a lateral flow immunoassay based on the principle of the double-antibody sandwich technique. The test strip is composed of the following parts: namely sample pad, reagent pad, reaction membrane, and absorbing pad. The reagent pad contains a conjugate formed by binding to a monoclonal antibody against SARS-CoV-2 nucleocapsid protein;the reaction membrane contains the secondary antibodies for Nucleocapsid protein protein of SARS-CoV-2. The whole strip is fixed inside a plastic device. When the sample is added into the sample well, conjugates dried in the reagent pad are dissolved and migrate along with the sample. If SARS-CoV-2 antigen presents in the sample, a complex formed between the anti-SARS-2 conjugate and the virus will be captured by the specific anti-SARS-2 monoclonal antibodies coated on the test line region (T). Absence of the T line suggests a negative result. To serve as a proce…
