Recently, information such as "eating before collecting nucleic acids will cause false positive nucleic acid" and "cold will activate the inactivated COVID-19 vaccine to test positive" have been circulated on Weibo, , Douyin , WeChat group circle and other platforms. Many netizens asked if this is true?

In response to this, Xinjiang Internet jointly verb refuting platform conducted verification from multiple parties.

Will eating before collecting nucleic acid cause false positive nucleic acid?

No scientific basis

Recently, information such as

Previously, in response to this issue, People's Daily reporter interviewed Li Dongzeng, chief physician of the Department of Respiratory and Infectious Diseases in Beijing You'an Hospital. Li Tongzhe said that the claim that diet causes false positive nucleic acids has no scientific basis. Xinjiang Disease Control and Prevention has also made a professional explanation on this issue. nucleic acid testing has nothing to do with food, because nucleic acid testing targets specific fragments in the new coronavirus, which does not intersect with other microorganisms or foods. Therefore, food does not cause nonspecific false positive results to appear. Simply put, we should eat and drink, and what we should eat and drink has little impact on the nucleic acid test results.

Will a cold activate the inactivated COVID-19 vaccine test positive?

has no direct relationship with

Recently, information such as

According to the Xinjiang Disease Control and Prevention, the inactivated new crown vaccine is prepared by wild viruses through culture, inactivation and other processes. After inactivated viruses, they have lost their pathogenicity and infectivity, but their genes are retained. After vaccination, the body will stimulate the production of specific antibodies, so the antibody test result will be positive, but the nucleic acid test result will not be positive. If it is a simple cold and there is no new coronavirus in the body, the new coronavirus nucleic acid test will not test positive, and it has nothing to do with vaccination.
