Nucleic acid testing cannot be performed by yourself. Nucleic acid testing is a technology that relies on a number of procedures such as sampling by professional inspectors, laboratory testing, analysis of the results, and reporting of the results, which cannot be accomplished by those who have not been trained in the technology and the system, and therefore individuals are not able to perform nucleic acid self-testing. Currently there exists a new crown antigen detection kit that can be operated by individuals. When a virus infects the human body, the viral proteins can be utilized as antigens to stimulate the body’s cells to produce antibodies. The antigen test actually detects the presence of the NeoCoronavirus proteins in the sample, which can be quickly detected with the kit. First, the patient can collect nasal and oral secretions with a swab provided by the product, and then drop the sample into the kit to observe the test results and determine whether the virus is present. However, this method has some limitations, compared with the nucleic acid test, the sensitivity is low, can not be used as a basis for diagnosis, still need to carry out nucleic acid testing.
