Antigen testing solutions are generally non-toxic extracts. First of all, the composition of the extracts used by different manufacturers generally varies considerably, but the main components are generally a biological buffer solution, surfactants and a small amount of preservatives. The main role of the buffer solution is to maintain the environmental conditions of the sample to ensure that the pathogen bioactive substances in the sample remain intact, so as to avoid affecting the results. In addition to the biological buffer solution, it also contains a certain amount of surfactant, the main role of surfactant is to cleave the cells that may be infected with the virus, so as to facilitate the subsequent extraction of antigens. Although the preservative may have some health effects on human beings, it will be highly diluted in the process of antigen detection, the concentration is very low, and the harm caused to human beings is negligible. Even inadvertent contact need not be too alarmed, rinse with water can be. Therefore, the antigen test solution has very little impact on human health, as long as the instructions are followed correctly. At the same time, we should also learn to dispose of it correctly to avoid a certain impact on the environment.
