About Our Cannabinoid (Marijuana) Screen, Blood

Note: Fasting is not required for this test.

This blood test detects the presence of cannabinoids, including the following cannabinoid chemicals: Delta-9 THC, 11-Hydroxy Delta-9 THC, 11-Nor-9 Carboxy THC. Cannabis, also commonly referred to as marijuana, is a psychoactive drug. Sometimes marijuana is prescribed as medicine.

Unlike urine tests, blood tests detect the active presence of THC in the bloodstream. In the case of smoked marijuana, THC typically peaks rapidly in the first few minutes after inhaling, then declines quickly within an hour. When marijuana is smoked, THC passes quickly from the lungs into the bloodstream. The blood carries the chemical to the brain and other organs throughout the body. It is absorbed more slowly when ingested in food or drink.


Marijuana Metabolites: Tetrahydrocannabinol (THC) can be detected for up to 7 days after initially taken.
With HealthLabs.com, you will receive your drug test results within 24-48 hours.
