Antigen preparation generally includes tutorials on cleaning hands, sample collection, sample extraction, testing, waste disposal, etc.:
1. Clean hands: Before antigen testing, hands should be strictly disinfected. ,clean. Then check whether the packaging of the kit is intact or damaged.
2. Sample collection: Clean the nasal cavity and tilt your head back slightly. Hold the tail of the nasal swab and enter it from one nostril, slowly go deep into the nasal cavity, rotate it at least 4 times inside the nasal cavity, and then repeat this operation on the other side of the nasal cavity.
3. Sample extraction: Immediately after sampling, put the nasal swab into the sampling tube, and rotate the swab vigorously to fully mix it with the treatment solution.
4. Test: Break off the cap of the processing bottle, take out the detection card, invert the processing bottle vertically, drop three drops of liquid into the sample hole, and wait for fifteen minutes. If color appears at C but not at T, the test card is negative. If color appears at both C and T, it is positive, and a bar on the T scale means the test is invalid.
5. Waste disposal: Put the test items into medical sealed bags and dispose of them as medical waste.
Antigen:
Refers to the substance that initially stimulates the immune system. Viruses or bacteria are typical representatives of the antigen group.
Antigens are mainly divided into alloantigens (blood transfusion, transplantation, pregnancy, etc.), xenoantigens (pet hair, etc.), plant antigens (pollen, food, etc.), and synthetic antigens (synthetic peptides, vaccines, etc.) , Microbial antigens (bacteria, viruses, fungi, parasitic protozoa, etc.). In short, non-self substances other than body components existing around us may become antigens.
