Spilling the liquid in the nucleic acid test tube on your hands is usually not infectious. The liquid in the nucleic acid test tube is a reagent protection liquid that is used to preserve the proteins from destruction and protect the integrity of the virus, contributing to the accuracy of the nucleic acid test results. The liquid is not toxic, corrosive, etc., and also contains no pathogenic components of the new coronavirus or other viruses. Infection generally refers to viral or bacterial infection, that is, pathogenic microorganisms, as well as parasites, etc., through different channels to invade the organism and growth and reproduction caused by pathological reactions and damage to the organism. The liquid in the nucleic acid test tube does not contain bacteria and viruses, and will not be used as a means of transmission, so when the liquid in the nucleic acid test tube is spilled on the hands, infection usually does not occur. To summarize, when the liquid in the nucleic acid test tube is spilled on the hands, it can be washed off in time, and usually will not cause infection and other harm.
