For the test, you will have to insert the nasal swab in both the nostrils up to 2 to 4 cm or until resistance is met. Roll the swab 4-5 times in both the nostril, then immerse it in the pre-filled tube and close the cap of the tube. Add two drops of liquid from the tube on the testing card and wait for 15 minutes for the result. In general, it will take 5-7 minutes to detect a positive case, but it is advised to wait for 15 minutes. Any result taking more than 20 minutes to appear will be considered invalid.
