COVID-19 Antigen Rapid Test

Coronavirus Antigen Rapid Test Cassette (Swab)

COVID-19 is an infectious disease caused by a new coronavirus that can spread from person to person. COVID-19 symptoms can range from mild (or no symptoms) to severe illness. The Coronavirus Ag Rapid Test Cassette (Swab) is an in vitro immunochromatographic assay for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 virus in nasopharyngeal (NP) swab specimens for clinical diagnosis of COVID-19.

How Does Coronavirus Antigen Rapid Test Work?

The COVID-19 antigen rapid test is for the detection of SARS-CoV-2 nucleocapsid protein antigen, detectable in upper respiratory specimens during the acute phase of infection. Positive results indicate the presence of viral antigens.

Instructions for Use


1. Sample Collection

  1. Remove a nasopharyngeal swab from the pouch.
  2. Place the swab into one of the patient’s nostrils until it reaches the posterior nasopharynx; keep insert until resistance is encountered or the distance is equivalent to that from the ear to the nostril of the patient
  3. Slowly rotate 3-5 times the swab over the surface of the posterior nasopharynx
  4. Slowly remove the swab from the nostril while rotating it.

2. Sample Preparation

  1. Peel off aluminum foil seal from the top of the extraction vial containing the extraction buffer.
  2. Place the swab into the extraction vial. Rotate the swab vigorously at least 5 times.
  3. Remove the swab by rotating against the extraction vial while squeezing the sides of the vial to release the liquid from the swab. Properly discard the swab.
  4. Close the vial with the provided cap and push firmly onto the vial.
  5. Mix thoroughly by flicking the bottom of the tube.

3. Detection

  1. Invert the extraction vial and hold the sample vertically above the sample well. Squeeze the vial gently. Allow three (3) drops of sample to fall into the sample well. 2 drops of the sample are required minimum volume to initiate the test run and invalid results will be obtained if 1 drop of sample is added to the cassette. Leakage of the sample is possible when 6 drops or more of the sample are added.
  2. Read and interpret the test result at 10 minutes. The test result should not be read and interpreted after 15 minutes.

Interpretation of Test Results


***Disclaimer: Please see the image from Detection (step 3) of the ‘Instructions for Use’ section. The picture is for representation only, markings on test cassette may vary.


POSITIVE: Both the Ag test line (T) and the control line (C) are colored in the Coronavirus Ag Rapid Test Cassette.


NEGATIVE: One coloured line appears in the control region. No apparent coloured line appears in the Ag test region.


INVALID: Control line fails to appear. Insufficient sample volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test cassette. If the problem persists, discontinue using the COVID-19 rapid test kit immediately and contact our administration..

Validated by Clinical Study


The Coronavirus Ag Rapid Test Cassette has been validated by a comprehensive clinical study in which 106 clinical samples were selected.

43 cases of positive samples confirmed by PCR test: tested with Coronavirus Ag Rapid Test Cassette, 38 cases were positive, 5 cases were negative. 63 cases of negative samples confirmed by PCR test: tested with Coronavirus Ag Rapid Test Cassette, 63 cases were negative, 0 cases were positive. The relative sensitivity was 88.37%, the relative specificity was 100%.

Limitation of Coronavirus Antigen Rapid Test

  1. This test is recommended for Healthcare professional use only.
  2. The test procedure, precautions and interpretation of results for this test must be followed strictly when testing. Failure to follow the Test Procedure and Interpretations of Test Results may adversely affect test performance and/or invalidate the Test Result.
  3. The test should be used for the qualitative detection of SARS-CoV-2 antigen in human nasopharyngeal swab specimens. Neither the quantitative value nor the rate of SARS-CoV-2 antigen concentration can be determined by this qualitative test.
  4. A negative test result may occur if the level of antigen in a sample is below the detection limit of the test.
  5. Positive test results do not differentiate between SARS-CoV and SARS-CoV-2.
  6. Positive test results do not rule out co-infections with other pathogens.
  7. False-negative test results are more likely during peak activity when prevalence of disease is high.
  8. False-positive test results are more likely during periods of low SARS-CoV-2 activity when prevalence is moderate to low.
