A nucleic acid test result of 1 means negative, usually with a capital one in parentheses. If the result shows 1 after receiving the nucleic acid test report card, it means negative. However, the Arabic numeral 1 does not usually appear, but the Chinese capitalized number one. In the case of the Omicronucleic Acid Test, for example, a negative result means that no Omicronucleic Acid Virus has been detected in the sample of the tested person, and that the tested person is not currently infected. However, due to the invisibility of omicron and the incubation period of the new crown virus after infection, the results of a nucleic acid test can not completely ensure safety, but also need to follow up and continue to do, if also negative, the results will also appear in the number of one, if there is something you do not understand in the test report can be consulted with the staff of the testing center.
