Covid 19 &
Flu A B
CHERTO SARS-CoV-2 & Influenza A+B is a test for the simultaneous detection of SARS-CoV-2, Influenza A, and Influenza B using a nasal swab sample. It is intended for self-use and helps determine whether symptoms are related to COVID-19 or influenza at the very first signs of illness.
The symptoms of these infections are often similar – fever, cough, fatigue and frequently overlap, which is why even doctors rely on testing to make a reliable distinction. If the correct infection is not treated, the risk of complications such as pneumonia, lung involvement, or worsening of chronic conditions increases.
The accuracy of CHERTO SARS-CoV-2 & Influenza A+B has been confirmed through clinical comparison with RT-PCR, a molecular laboratory method considered the gold standard. This provides laboratory-level precision at home.
Remove the sterile swab from its packaging.
Insert the swab into the nostril until slight resistance is felt, approximately 2 cm inside.
Rotate slowly, rubbing the inside of the nostril against the nasal wall 5 to 10 times.
Repeat in the other nostril.
Place the swab into the extraction buffer tube, ensuring it touches the bottom. Mix thoroughly. Press the tip of the swab against the inner wall of the tube and rotate for 10 to 15 seconds.
Remove the swab while squeezing the tube to extract the liquid from the swab. Close the cap or attach the dropper tip to the tube.
Turn the tube upside down and add 3 drops of the extracted specimen into each sample well marked “S” on the cassette. Start a timer. Read the result after 10 minutes. Do not read after 20 minutes.
Two colored lines appear in the COVID-19 window: one in the control region C and one in the test region T.
Two lines appear in the FLU A+B window: one in region C and one in region A.
Two lines appear in the FLU A+B window: one in region C and one in region B.
Three lines appear in the FLU A+B window: one in region C and one each in regions A and B.
Only one line appears in the control region C, with no line in regions T, A, or B.
The control line does not appear. Possible reasons include insufficient sample volume or incorrect procedure execution.
