Use of Quantitative LC-MS/MS Methods to Compare Conventional Blood Collection and Microsampling in Non-human Primate

Toxicokinetic evaluation is a regulatory and scientific requirement in the drug development process. To obtain plasma, blood is generally withdrawn by a conventional venous collection method. Microsampling is a less invasive sampling technique, which allows to reduce the stress correlated to the conventional blood sampling and to decrease the number of rodents for a preclinical study. The implementation of microsampling in particular, in non-human primate can reduce the stress and promote a positive interaction with technical staff which improves the overall well-being of the animal (refinement).

In this poster we summarise the work done to evaluate the possible influence of the blood sampling method on drug plasma concentrations, using LC-MS/MS methods in non-human primate for four drugs selected based on acid-base and volume of distribution properties.

The poster was presented by our expert Rossella Cardin at the 24th International Reid Bioanalytical Forum held in Cambridge, UK, on June 13-16, 2022.
