Antigen Swab Test Kit of SARS-CoV-2 25 Tests/Kit CE Accuracy 99.68%
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%.
For the anterior nasal swab method,263 specimens were collected.A
sensitivity of 96.8% and a specificity of 100.00% were determined
for the test. The accuracy is 98.48%.
