Covid 19 Antigen Professional Test 10 Tests/Kit CE Sensitivity 98%
Antigen Swab Test Kit Principle
The Green Spring® SARS-CoV-2 Antigen Rapid Test is a qualitative membrane-based immunoassay for the detection of the nucleocapsid protein antigen of SARS-CoV-2 with the detection line area coated with SARS-CoV-2 antibodies. The sample reacts with SARS-CoV-2 antibodies in the test line area. If the sample contains SARS-CoV-2 antigen, a colored line will appear in the test line area (T). As a program control, a colored line appears in the control line area (C), indicating that the correct volume of sample has been added and that membrane wicking has occurred correctly.
Clinical Performance
The clinical performance of the Green Spring ® SARS-CoV-2 antigen rapid test was determined in prospective,randomized, single-blind studies. A total of 310 nasopharyngeal specimens from symptomatic and asymptomatic patients were collected within 5 days of the onset of initial symptoms. The performance of the kit was compared with the results of a commercially available molecular test. The test was found to have a sensitivity of 98% and a specificity of 100.00%. The accuracy is 99.35%.
