Test Principles

The CareStart COVID-19 Antigen Test is a lateral flow immunochromatographic assay for the detection of extracted nucleocapsid protein antigens specific to SARS-CoV-2 in swab specimens directly collected from individuals who are suspected of Covid-19 by their healthcare providers.


1. Peel off aluminum foil seal and rotate the swab inside the extraction vial vigorously at least 5 times.

2. Remove the swab, close the vial by pushing the cap onto the vial and squeeze the vial gently to release 3 drops of sample to the sample well.

3. Read the test results between 10 and 15 minutes

Results Interpretation

  • The color intensity in the test region will vary depending of the SARS-CoV-2 antigen present in the sample.

  • Any faint colored line in the test region should be considered as positive.

  • Rerun the test one time using the remaining specimen in the extraction vial.
