Using orange juice as antigen test, the result turned out to be "positive"! What else will be tested as false positive?

Soda, red bull, vodka, brandy, etc. Will be tested as false positive.

There is a saying on the Internet that using orange juice to do antigen test will show positive results, so you can't eat oranges or drink orange juice when doing antigen test. But experts believe that this statement has no scientific basis. It is said on the internet that orange juice will be positive for antigen test. It is to squeeze orange juice directly on the antigen test paper for testing, instead of collecting samples after drinking orange juice. In fact, not only orange juice, but also soda water, red bull and alcohol that people usually drink, as well as vodka brandy, etc. are dripped on the COVID-19 antigen reagent test box. Drops will also appear on this test box.

When introducing this problem, experts told people that most anti-inflammatory tests will collect nasal swabs, and he will not collect samples of people's mouth and throat at all, so it has nothing to do with what people eat and drink, and people's daily diet will not affect the results of antigen testing at all. In other words, the online saying that eating oranges as antigens will win is simply not credible and has no scientific basis.

COVID-19 antigen detection kit captures specific antigens through special antibodies. There is a special treatment solution in this kit, and the pH value of the treatment solution should be kept stable. If the pH value changes, it will affect its detection. Results People directly drop the ammonia water and brandy of orange juice into the kit, which will change the pH value of the treatment solution, and then the antigen result will be abnormal.

COVID-19's antigen detection kit can only detect the correct results if it is used correctly, and its detection results have reference value. If orange juice and drinks are directly dropped into the kit, resulting in a positive result of the reagent, then it has no reference significance and no meaning. It is suggested that when using the COVID-19 antigen test kit, you should use it correctly according to the regulations and procedures, and don't blindly believe the online statement.
