Detailed Description

The LYHER® antigen test kit for the novel coronavirus (SARS-CoV-2, which causes COVID-19) is a diagnostic test. The test is to be used as an aid in the rapid diagnosis of infection with SARS-CoV-2. The test is used for the direct and qualitative detection of viral protein (the antigen: N protein) of SARS-CoV-2 in nasal mucus. The rapid test uses highly sensitive antibodies to measure the N protein. With this self-testing test, you can find out if you are infected with the virus caused COVID-19. To be used as a self-test from the age of 16. For children under the age of 16, a legal guardian will perform the test or the test will be done under their supervision.
A negative result of the LYHER® Novel Coronavirus (COVID-19) Antigen Test Kit does not exclude infection with COVID-19. If symptoms are suggestive of COVID-19, a negative result should be verified by laboratory test.

About COVID-19
COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.

01. Insert the cotton swab into a nostril gently. Insert the tip of the cotton swab 2-4 cm (for children is 1-2 cm) until resistance is felt.

02. Swirl the cotton swab along the nasal mucosa 5 times within 7-10 seconds to ensure that both mucus and cells are absorbed.
Repeat the process with the same cotton swab in the other nostril to ensure that sufficient sample is taken from both nasal cavities. Pull the swab out of the nasal cavity gently.


03. Dip the head of the cotton swab into the diluent after taking the sample from the nose.
04. Squeeze the sample tube with a cotton swab 10-15 times to mix evenly so that the wall of the sample tube touches the cotton swab.
05. Keep it upright for 1 minute to keep as much sample material as possible in the diluent. Discard the cotton swab. Place the dropper on the test tube.

Test Procedure


06. Add the sample as follows. Place a clean dropper on the sample tube. Invert the sample tube so that it is perpendicular to the sample hole (S). Add 3 DROPS of the sample. Set the timer for 15 MINUTES.
07. Read the result after 15 MINUTES in sufficient lighting condition. The test result can be read at 15 MINUTES after adding the sample to the test cassette. The result after 20 minutes is invalid.
08. POSITIVE: two colored lines appear in the test cassette
NEGATIVE: only a single colored line appears in the control region (C).
INVALID: The control line (C) does not appear in the test cassette.
