How to do nucleic acid testing at home?

Methods for detecting nucleic acids at home:

Buy a self-test nucleic acid test box first.

1. Clean hands: Before antigen detection, hands should be strictly disinfected and cleaned. Then check whether the package of the kit is intact.

2, sample collection: clean the nasal cavity, head slightly backward. The tail of the hand-held nasal swab enters through one nostril, slowly penetrates into the nasal cavity, rotates in the nasal cavity for at least 4 times, and then repeats this operation in the other 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. Detection: break the lid of the processing bottle, take out the detection card, turn the processing bottle upside down vertically, drop three drops of liquid into the sample hole and wait for fifteen minutes. The test card is colored at c and not negative at t. If both C and T are colored as positive, a bar on the T scale indicates that the test is invalid.

5. Waste disposal: put the tested articles into medical sealed bags and treat them as medical waste.

Principle of antigen detection:

It is necessary to immobilize the corresponding virus protein antigen on carriers such as colloidal gold or latex. If the sample contains viral proteins, these proteins will combine with antibodies on the carrier, thus discoloring the test paper. Novel coronavirus antigen test is usually used in acute infection period, and the positive result can be used for early metastasis and rapid management of suspected population, but it cannot be used as a diagnostic basis for novel coronavirus infection.
