Unlike other tests, thankfully food, drink and smoking is not an issue for us as the swab is a strictly and purely nostril only test.
However, nasally ingested medication such as nasal sprays and antihistamines may influence the result of the test.
3 hours should pass between any nasally ingested substances and the test being taken and there is no issue.
Although drinking will not affect the test result, our nurses will not continue the testing process, should any individual appear to be intoxicated.
