A method was developed for quantitating 9-carboxy-ll-nor-A'-tetrahydrocannabinol in human urine as part of the process for validating an automated enzyme immunoassay for marijuana metabolites. Sample cleanup was accomplished using a mixed-mode solid-phase extraction. 9-Carboxy-ll-nor-A'-tetrahydroca
A method for the rapid and robust confirmation of 11‐nor‐∆9‐tetrahydrocannabinol‐9‐carboxylic acid (THCA) in urine involving basic hydrolysis with NaOH and direct injection of the hydrolysate in a column‐switching LC‐MS‐MS system was developed and validated. THCA‐d3 was used as internal standard. De
Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation
