Coke does not cause a positive New Crown Antigen. Coke is a common carbonated beverage and can be consumed before the test. It has not been found to affect the results of the test and cause false positives, so Coke does not cause a positive test. The new crown antigen test uses antibodies in a kit to look for the presence of antigens in the specimen. The test can be done at home by the test taker, and the results are usually available in about 15 minutes. However, there are limitations to the Neo-Crown antigen test and the results may be inaccurate. If the new crown antigen test is positive, a nucleic acid test is also required. If the nucleic acid test is also positive, the case should be reported immediately according to local policy for quarantine and treatment. If the nucleic acid test is negative, treatment may be withheld, but the nucleic acid test should be repeated several times to ensure accurate results.
