Who it is for
Healthcare providers order this test in emergency rooms, treatment programs, or during routine monitoring. Employers may require it for safety-sensitive jobs, but a clinician interprets the results.
Preparation
No fasting or special preparation is usually needed. Tell your provider about any prescription or over-the-counter drugs you take, as they can affect results.
Results and what they mean

Frequently asked questions
How long do drugs stay in blood?
Most drugs are detectable for hours to a few days, depending on the substance and your body. Blood tests show recent use better than urine tests.
Can prescribed medications cause a positive result?
Yes, some prescription drugs can trigger a positive screen. Always tell your provider about all medications you take.
Is the test confidential?
Your results are protected health information and are kept private. They are shared only with those you authorize or as required by law.
What if I get a positive result?
A positive result does not automatically mean misuse. Your clinician will consider your history and may order a confirmatory test.
