Urine test to detect recent marijuana exposure.
This urine test checks for recent exposure to marijuana. It detects the presence of Delta-9 tetrahydrocannabinol metabolite (THC-COOH), a biomarker indicating marijuana use. If the initial test is positive, a confirmation test is performed at no extra cost. Results are typically available within a few business days, but processing times may vary. An independent healthcare coordinator may contact you if results fall outside expected ranges. Independent physicians are available to answer questions.
