Antigen testing is exemplified by the new coronavirus antigen test, where fever usually does not affect the antigen test results. Antigen tests screen for viruses by detecting their surface proteins and are specific and generally do not react to viruses other than the target virus being tested.
The medical name for fever is febrile, and there are more causes of fever, which are commonly seen in various infectious diseases, such as upper respiratory tract infections, tuberculosis, lung abscess, sepsis, bronchitis and other diseases, but also in malignant tumors, drug fever, rheumatoid arthritis, systemic lupus erythematosus and other diseases. As long as the fever is not caused by a new coronavirus infection, it usually does not affect the antigen test.
Factors affecting the results of antigen detection include the reagent itself, such as the concentration of the antibody, specificity, affinity, and the width of the equivalence band. In addition, proper handling can also have a direct impact on the antigen test results.
In summary, fever does not directly affect antigen test results.
