What this test is
This test screens for cannabinoids, the active compounds in marijuana, using a blood or urine sample. It can indicate recent use, though it does not measure impairment or frequency of use.
What it measures
- THC (tetrahydrocannabinol) — the primary psychoactive compound in marijuana
- THC-COOH (carboxy-THC) — a metabolite that indicates recent or past use
- Cannabidiol (CBD) — a non-psychoactive cannabinoid sometimes included in screens
- Cannabinol (CBN) — a breakdown product that may suggest older use
What the test involves
The test involves a standard blood draw from a vein in your arm or a urine sample collected at a laboratory. Both methods are quick and usually require no special preparation beyond following the lab's instructions.
Why it is often ordered
A clinician may order this test as part of a routine health evaluation, pre-employment screening, or monitoring for substance use. It is also used in some clinical settings to assess potential drug interactions or compliance with treatment plans.
Preparation
Preparation is minimal, but you should follow the specific instructions provided by the collection laboratory. This may include avoiding certain foods or medications, so always confirm details with the lab before your visit.
How results are reported
Results are reported as either negative or positive, with positive results sometimes followed by a confirmation test to identify specific cannabinoids. Reference ranges and cutoff levels vary by laboratory, so your results should be interpreted in the context of the lab's own standards.
