Tests and diagnosisBy Mayo Clinic Staff
Diagnosing drug addiction (also called substance use disorder) requires a thorough evaluation and often includes an assessment by a psychiatrist, a psychologist, or a licensed alcohol and drug counselor. Blood, urine or other lab tests are used to assess drug use, but they're not a diagnostic test for addiction. These tests may be used for monitoring treatment and recovery.
For diagnosis of a substance use disorder, most mental health professionals use criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, to diagnose mental conditions. This manual is also used by insurance companies to reimburse for treatment.
DSM-5 criteria for substance use disorder include a behavior pattern of drug use that causes significant problems and distress, regardless of what drug is used.
You may have a substance use disorder if at least two of these issues occur within a 12-month period:

- You have intense urges for the drug that block out any other thoughts
- You aren't meeting obligations and responsibilities because of your substance use
- You keep using the drug, even though you know it's causing problems in your life

- You use the substance in situations that may be unsafe, such as when driving or operating machinery
- You use the substance even though you know it's causing you physical or psychological harm
