Covid19 Nasal Swab Rapid Test

The CareStart point-of-care test detects antigens specific to SARS-CoV-2, the coronavirus that causes COVID-19. WorkCare onsite clinicians use a nasopharyngeal swab to collect nasal secretions that may contain infectious particles from employees. Results appear on a test strip in 10 minutes.

The U.S. Food and Drug Administration (FDA) granted Emergency Use Authorization (EUA) for the test in mid-October 2020. Access Bio reported 88.4 percent sensitivity and 100 percent test specificity in a related document describing intended use.

Methodology

The rapid antigen test is a lateral flow immunochromatographic assay for the detection of extracted nucleocapsid protein. After a specimen is collected – optimally within five days of symptom onset – the swab is placed in an extraction buffer solution. The extracted swab sample is added to the well of a test device. When the sample migrates through the test strip, SARS-CoV-2 viral antigens bind to anti-SARS-CoV-2 nucleocapsid protein antibodies to form an immune complex that is captured by the device.

Results are indicated by lines that appear on the device. Two colored lines in control region “C” and test region “T” indicate the presence of viral antigens. One colored line in control region “C” indicates a negative result. The absence of a colored line in region “C” indicates an invalid test. No additional equipment or specialized instruments are needed for sample analyses.
