The COVID-19 rapid antigen test kit we use is a lateral flow immunochromatographic assay intended for the qualitative detection of the nucleocapsid protein antigen from SARS-CoV-2 in nasopharyngeal swab specimens directly collected from individuals suspected of COVID-19 within 5 days of symptom onset. Test results are interpreted at 10 minutes.
Per the manufacturer, the testing can identify acute infection in symptomatic patients with 88.4% sensitivity and 100% specificity.
NOTE: If you are a healthcare professional who believes you have been directly exposed while at work by a patient, you should consult your place of work for specific occupational health guidance about whether to stay home or continue working while waiting for your results. You should adhere to recommendations set forth by your employer or the Department of Health, as they may differ from the CDC's guidelines.
