▷ Reagent validity date refers to the last preservation date of the reagent, the reagent that exceeds the validity date can still be used normally, but you need to use a standard solution every week to test, if using a standard solution with a concentration close to the test upper limit to measure and get accurate results, then the reagent can still work normally in the whole test range.
