Blood testing in toxicology has its own role to play in determining compliance with prescription regimens, court mandates, substance-abuse treatment and other directives. With the addition of blood testing, you can begin using the right test, at the right time, for the right information.
Unique Traits of Blood Testing
Urine drug testing provides a view of a patient’s medication use in a relatively short window of detection, but it can’t identify the amount of drug that’s been taken or which substances are live in a patient’s system.

Blood is also one of the only matrices capable of providing pharmacological information on drug impairment and medication tolerance.
Benefits of Blood Testing
Blood testing offers several benefits to healthcare providers, including the following:
- Supports positive correlation between drug concentration and dose using steady-state blood concentrations
- Identifies if more or less medication is being taken than prescribed
- Documents patient tolerance to toxic levels of medication
- Precursory test that determines the need for additional testing (ex: pharmacogenetic testing
