Quantitative analysis of cannabinoids and metabolites in oral fluid by volumetric absorptive microsampling combined with UHPLC-HRMS
Thiebot et al.
The finding, in our words
Researchers developed an assay to quantify seven cannabinoids and metabolites from 20 µL oral fluid self-collected via a VAMS device, achieving a limit of quantitation of 0.5 ng/mL. In six cannabis consumers, the method successfully quantified Δ9-tetrahydrocannabinol up to 6236 ng/mL, demonstrating the feasibility of low-volume volumetric microsampling for non-invasive toxicology and roadside testing.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
This study compared four dried blood spot devices for glucocorticoid detection, finding that the Mitra VAMS device offered the best combination of analytical recovery and user usability, whilst the HemaXis DB10 showed the least bias compared to whole blood.
The study compared five microsampling devices, including Mitra tips and Tasso-M20, for detecting 27 steroid esters in dried blood by LC-MS/MS, and found that methanol extraction with Girard's reagent P or T provided the best screening sensitivity with detection limits of 0.05 to 1.0 ng/mL, while methoxyamine derivatization was recommended for confirming boldenone and certain testosterone esters. The Tasso-M20 device produced chromatographic interference with methanol extraction that was only partially resolved by using mixed solvents, at the cost of lower recoveries.
The study validated a VAMS method for cocaine and metabolites in blood and plasma, achieving good extraction yield, precision and accuracy with analyte stability exceeding two months at room temperature. Results from VAMS correlated well with conventional fluid samples, supporting its use for decentralised forensic and toxicological monitoring without venepuncture or cold chain.
The study developed and validated an LC-MS/MS method for THC, its metabolites and synthetic cannabinoids in both dried blood spots and VAMS, showing that VAMS eliminates the haematocrit effect that limits DBS accuracy, thereby providing a reliable tool for toxicological and anti-doping analysis in decentralised settings.
The study developed and validated an LC-MS/MS method using volumetric absorptive microsampling to quantify cathinone analogues in dried urine, plasma and oral fluid, showing satisfactory linearity, precision, recovery, matrix effects, selectivity and stability, and was applied to real samples from users, offering a reliable decentralised sampling strategy for forensic toxicology and sport drug testing.
