Delta-8 and Delta-9-Carboxy-Tetrahydrocannabinol (THC) Confirmation, Chain of Custody, Random, Urine
Use
This test is useful for the detection and confirmation of drug use of cannabis/marijuana and specifically identifies and quantifies delta-8 carboxy tetrahydrocannabinol (THC-COOH) and delta-9-THC-COOH. It is particularly relevant where chain-of-custody is required to ensure the results could be used in a court of law. The test confirms initial immunoassay screening results, which are crucial in medico-legal cases or when there is denial of cannabis use and a positive screening result.
Special Instructions
Not provided.
Limitations
The test confirms the presence of delta-8 and delta-9 carboxy THC-COOH metabolites in urine, which indicates marijuana use. However, it may not distinguish between recent use and chronic exposure since THC metabolites can persist in urine for extended periods, especially in regular users. It does not provide information on the source of THC exposure (e.g., smoking versus ingestion) or the time since last use.
