What does it mean if an antigen test was done twice with one negative and one positive result? What should I do?
Disease description:
To ensure accuracy, my colleague performed the antigen test three times. The results showed one negative and one positive out of two tests. What could this mean, and what should be done?

The antigen test was performed twice, yielding one negative and one positive result. This discrepancy could be due to testing errors, inactivated reagents, changes in viral load, or other factors. Effective treatment should be initiated after the underlying cause is clearly identified. Additionally, such inconsistent results may also arise from early or late stages of infection, among other reasons, and timely medical evaluation and diagnosis are necessary.
