Since the beginning of the ambush, most parts of the country have opened the "sauna day" mode. Many people are very concerned about whether the covid-19 antigen detection kit stored at home also needs "heatstroke prevention and cooling" under high temperature and humidity. The reporter of science and technology daily inquired about this matter with Tianjin boosis Biotechnology Co., Ltd. (hereinafter referred to as boosis), which produces covid-19 antigen detection kits. Liu Chaoyang, manager of the rapid diagnosis Department of the company, said: "as long as the covid-19 antigen detection kit and extraction solution are not exposed to direct sunlight for a long time, generally speaking, storage at room temperature will not affect the accuracy of its detection." The reporter learned that the storage temperature of most covid-19 antigen detection kits in the market is 2 to 30 ° C, or 4 to 30 ° C. at the same time, it is required to keep them dry and away from light. In this regard, Liu Chaoyang introduced that generally speaking, if the indoor temperature exceeds the upper limit of the storage temperature for a long time, it will cause the coronavirus antigen detection kit to accelerate "aging". Because the biological raw materials involved in the covid-19 antigen detection kit, such as antigen and antibody, will remain active for a long time under high temperature, that is, high energy, which will make it lose its activity faster and even have the possibility of protein denaturation, thus shortening the effective period of the product. "Of course, the emphasis here is on 'long time'. If the temperature exceeds the upper limit once or twice, it will not affect the covid-19 antigen detection kit." Liu Chaoyang pointed out that compared with ordinary biological agents, the storage conditions of the covid-19 antigen detection kit are relatively loose, and there is no problem in the air-conditioned room. Unlike many immune products, they are required to be stored within 2 to 8 degrees Celsius. However, if the ambient temperature of the covid-19 antigen detection kit exceeds 30 ° C for a long time, it is recommended to put it in the refrigerator for cold storage. Liu Chaoyang stressed that never put the covid-19 antigen detection kit in the freezer for storage. "After freezing, the bottle may swell and crack. Repeated freezing may also affect the properties of the extraction solution, resulting in precipitates; at the same time, the detection card may be frozen, and the surface film may peel off." Since the covid-19 antigen detection kit is sealed and packaged in an aluminum foil bag, there is no need to worry about food contamination after it is put into the refrigerator. However, in order to avoid food contaminating the outer packaging of the covid-19 antigen test kit, which will cause people to contaminate their hands when using it for testing, and then affect the test results, it is recommended to put a fresh-keeping bag on the covid-19 antigen test kit before putting it into the refrigerator. It should be specially reminded that after taking out the coronavirus antigen detection kit from the refrigerator compartment, do not immediately unpack it for use. It must be left for a period of time to recover its temperature to room temperature before testing. "It's good to judge when you can unpack and use it. It's OK to touch it with your hands." Liu Chaoyang explained that the reason why the covid-19 antigen detection kit should be "warmed" is that the water vapor in the air will liquefy and agglutinate on the low-temperature detection card, which is often called "moisture absorption", which will affect the accuracy of the detection results. After unpacking, the covid-19 antigen detection kit should be used as soon as possible within 1 hour. The temperature of the use environment is recommended to be 15-30 ° C
