Using Vicks inside your nose can potentially interfere with your COVID-19 rapid test results. The ointment's oily barrier can prevent the swab from properly collecting the virus or interfere with the test's chemical reaction, leading to an inaccurate result. To ensure accuracy, please gently blow your nose to clear out any excess ointment before taking the swab. Do not aggressively rinse your nose with water right before the test, as this might dilute the sample.
