COVID-19 antigen test paper guide

First blow your nose with toilet paper, unpack the nose swab, avoid touching the head of the swab with your hand, slightly tilt your head, hold the tail of the swab with one hand, stick it into one side of the nostril, slowly go back 1 to 1.5cm along the bottom of the lower nasal tract, and then rotate it in the nasal cavity for at least 4 circles for at least 15 seconds. Then, repeat the same operation on the other nasal cavity with the same swab, and the nasal swab after collecting the sample shall be tested according to the instructions.
