When is the best time to test blood levels of a drug?
Checking the blood level of a drug at consistent times of day and consistent times after the last dose of medication is taken allows the doctor to compare levels at different dosages. Routine blood levels are best measured when the amount of the drug in the bloodstream is at its lowest point, which is called the trough level. This generally corresponds to the time just before the medication is taken.
