Iranian Researchers Produce Kit for Fast Detection of Covid-19
The technologists at one of the knowledge-based companies have produced and offered to the market various types of rapid detection kits containing nanoparticles, and their corona detection kit can detect the infection in less than 15 minutes with high accuracy, the website of Iran Nanotechnology Innovation Council (INIC) reported.
The knowledge-based company has produced and supplied to the market the rapid detection kit for Covid-19 (SARS-CoV-2019), the rapid detection kit for Troponin I (TnI), the pregnancy rapid test (HCG) and the Rapid Fecal Occult Blood (FOB) detection kit.
The rapid Covid-specific antigen test is a rapid membrane-based lateral flow immunoassay for the qualitative detection of SARS-CoV-2 antigens. During the test, the corona antigens, possibly present in the patient's sample, react with the nanoparticles coated with the antibody present in the test. As a result of chromatography, the resulting complex moves forward due to the capillarity in the strip membrane.
If the sample contains SARS-CoV-2 antigens, they will bind to the SARS-CoV-2 antibodies coated in the test line (T) region and produce a colored line on the test strip, indicating a positive result.
A colored line should always appear in the Control (C) region and another line should be in the Test (T) region. If the sample contains SARS-CoV-2 antigen, a colored line appears in the test line region, indicating a positive result. If the sample does not contain SARS-CoV-2 antigen, noncolored line appears in this area, indicating a negative result. As a procedural control, a colored line always appears in the control line region, indicating that the correct sample volume has been added and the membrane has been wetted through.
