About the Cannabis Test
The cerascreen® Cannabis Test examines your blood sample for traces of THC, cannabidiol and a total of four metabolites. The blood test can detect active cannabis ingredients and metabolites if you have consumed them within the last 48 hours.
With the cerascreen® Cannabis Test, you do not get a quick test, but a blood test that has been professionally analysed by a highly reliable laboratory.
The following substances are examined: tetrahydrocannabinol (THC), THC-OH, THC-COOH, cannabidiol (CBD), CBD-OH, CBD-COOH.
Please note: The cerascreen® Cannabis Test is not a substitute for medical or professional advice or diagnosis. Please talk to your doctor if you suspect that you have problems with cannabis abuse.
