| Normal Values: |
| "Normal" levels vary according to the institution performing the test. Blood can be tested for the presence and levels (amounts) of medications. Urine screening is usually reported as positive (substance is present) or negative (absent), but the level of certain substances can also be measured fairly accurately in urine. Therapeutic levels are measured for prescribed or over-the-counter medications (see the specific medication). Alcohol, prescription medications that are not prescribed, and illegal drugs are not normally present. |
| What abnormal results mean: |
| The presence of illegal drugs or drugs not prescribed for the person indicates illicit drug use. Elevated levels of alcohol or prescription drugs can indicate intentional or accidental intoxication and/or overdose. Additional conditions under which the test may be performed:
