Do your own antigen tutorial at home as follows:

Generally speaking, when using novel coronavirus antigen kit, hands should be cleaned and disinfected first. Then open the medicine box, take out the items in the medicine box and read the instructions carefully, because there are subtle differences between different brands and operations to avoid getting wrong results.

After reading the instructions, open the sample extract and pour it into the sample extraction tube. If there are many secretions in the nasal cavity, clean the nasal cavity before testing, and take out the cotton swab after cleaning the nasal cavity to avoid touching the cotton swab head with your hands, so as not to affect the test results.

During the test, the head is raised backwards, the cotton swab is pushed in the nasal cavity for about 1cm to about 1.5cm, and rotated in the nasal cavity for about 15 seconds, so as to ensure that the contact surface and sampling amount are increased during sampling, and then the same cotton swab is placed in the other nostril for sampling.

After taking the sample, put it into the extraction tube, put the cotton swab head into the extraction solution, rotate it for about 30 seconds, squeeze the cotton swab head five times, turn over the extraction tube, and drop about three drops of the extraction solution from the cover onto the detection card for detection.

After the detection of novel coronavirus antigen, the samples should be sealed to avoid exposure to air, and the result can be judged in about 10 minutes to 15 minutes.
