Normal Values
Normal value ranges for over-the-counter or prescription medications may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results. A negative value usually means that alcohol, prescription medications that have not been prescribed, and illegal drugs have not been detected.
A blood toxicology screen can determine the presence and level (amount) of a drug in your body. Urine sample results are usually reported as positive (substance is found) or negative (no substance is found).
What do Abnormal Results Mean?
Elevated levels of alcohol or prescription drugs can be a sign of intentional or accidental intoxication or overdose. The presence of illegal drugs or drugs not prescribed for the person indicates illicit drug use.
