Performing a test

Simple to perform and fast results in 15 to 30 minutes*

sars cov 2 antigen self test nasal procedure step 1
Collecting a nasal sample

Insert the swab into one nostril. Slowly slide it approx. 2 cm forward. Rotate the swab 4 times (for approx. 15 seconds) against the lining of the nasal wall, before removing it. Repeat in other nostril using the same swab.

Sample preparation


Insert the swab into an extraction buffer tube, squeeze the tube and stir the swab more than 10 times. Remove the swab while squeezing the sides of the tube. Press the nozzle cap tightly onto the tube.

Read the results


Read the test result at 15 to 30 minutes. Do not touch or move the test device until the result can be read.


WARNING! Test results that are read before 15 minutes or after 30 minutes may be incorrect.

WARNING! Failure to squeeze the tube can lead to incorrect results.

*Before using the Sars-Cov-2 Antigen Self Test Nasal, carefully read the Instructions for Use and all included warnings and precautions. Wash your hands or use hand sanitizer before and after performing the test. 

Interpreting results

Test results are quick and easy to read

rapid antigen test nasal 2.0 positive result
Positive test result


If both colored lines C and T are visible, even if they are faint or not uniform, the test result is positive. This means the test detected the virus protein in the sample. The tested person is very likely infected with SARS-CoV-2.


Control line C: Indicates that the test is working correctly 

Test line T: visible if SARS-CoV-2 antigen was detected

rapid antigen test nasal 2.0 negative result
Negative test result


A visible control line C alone means the test worked correctly. The test result is negative. No virus protein could be detected in the sample. The tested person is unlikely infected with SARS-CoV-2.

Invalid test result

If a control line (C) is not visible, or only the line marked with a T, the result must be considered invalid. The test is not working correctly and you should perform another test using a different test kit.

  1. Roche Diagnostics. SARS-CoV-2 Rapid Antigen Self Test Nasal, Package Insert 2022-05, V1.0; Relative sensitivity and relative specificity are compared to RT-PCR.
Intended use

This test is an in vitro nucleic acid amplification test for the qualitative detection of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) in patient specimens.* The test utilizes amplification of target DNA by the Polymerase Chain Reaction (PCR) and nucleic acid hybridization for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae. This test is intended to be used as a diagnostic as well as a screening tool.
