This swab test is intended for the rapid detection of COVID-19  - results available within 15 minutes with high accuracy.

​

 

 

 

Use the nasopharyngeal swab supplied in the kit

Carefully insert the swab into the nostril of the patient, reaching the surface of posterior nasopharynx that presents the most secretion under visual inspection.

Swab over the surface of the posterior nasopharynx.

Rotate the swab several times. Withdraw the swab from the nasal cavity.

 

 

Insert the test extraction tube into the workstation

Make sure that the tube is standing firm and reaches the bottom of the workstation

Add 0.3 mL (about 10 drops) of the sample extraction buffer into the extraction tube.

Insert the swab into the extraction tube which contains 0.3 mL of the extraction buffer. Roll the swab at least 6 times while pressing the head against the bottom and side of the extraction tube. Leave the swab in the extraction tube for 1 minute.

Squeeze the tube several times with fingers from outside of the to immerse the swab

Fit the dropper tip with filter on top the extraction tube tightly

Remove the swab. The extracted solution will be used as test sample.

 

 

Allow the test device, test sample and buffer to equilibrate to room temperature prior to testing

 

Remove test device from the sealed pouch just prior to the testing and lay flat on work bench.

Ensure the nozzle with filter is fitted on to the sample extraction tube tightly.

Reverse the sample extraction tube, and add 4 drops (about 100 μL) of test sample by squeezing the extracted

solution tube into the sample window.

Wait for the colored band(s) to appear. The result should be read in 15 minutes.

Do not interpret the result after 20 minutes.

 

POSITIVE - The presence of two lines as control line (C) and test line (T) within the result window indicates a positive result.

NEGATIVE* - The presence of only control line (C) within the result window indicates a negative result.

INVALID - If the control line (C) is not visible within the result window after performing the test, the result is considered invalid. Some causes of invalid results are because of not following the directions correctly or the test may have deteriorated beyond the expiration date. It is recommended that the specimen be re-tested using a new test.

Note: The intensity of color in the test line region (T) may vary depending on the concentration of analytes present in the specimen. Therefore, any shade of color in the test line region (T) should be considered positive. Please note that this is a qualitative test only and cannot determine the concentration of analytes in the specimen. Insufficient specimen volume, incorrect operating procedure or expired tests are the most likely reasons for control band failure.

 

(*Negative results do not rule out SARS-CoV-2 infection, particularly those who have been in contact with the virus. Follow up testing with a molecular diagnostic test should be considered to rule out infection in these individuals.)

 

In-vitro use only. Please note, each box includes 1 x work station and 2x buffer solutions, therefore it can not be split up.

 

The Healgen Covid-19 Antigen Test (Swab) is an in vitro immunochromatographic assay for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in nasopharyngeal (NP) swab specimens directly or after the swabs have been added to viral transport media from individuals who are suspected of COVID-19 by their healthcare provider. It is intended to aid in the rapid diagnosis of SARS-CoV-2 infections. The Healgen Covid-19 Antigen Test (Swab) does not differentiate between SARS-CoV and SARS-CoV-2.
