Assessment of low volume sampling technologies: utility in nonclinical and clinical studies.

Background: Low volume sampling technologies have come a long way; however, their uptake has been slow due to logistical and perceived implementation challenges. Additional studies are needed to overcome these barriers. Materials & methods/results: Here we present two studies where different sampling technologies were evaluated to determine the feasibility of their implementation. First, we evaluated pharmacokinetic profiles for anti-gD in rats using three tail bleed sampling methods, glass capillary tubes, Shimadzu MSW2® and the Neoteryx Mitra® microsampler. Second, we evaluated two low volume-sampling methods to measure drug levels from patients treated with anti-A therapeutic. This evaluation used whole blood finger pricks for Neoteryx Mitra and plasma from capillary blood using TASSO OnDemand technology to compare results to established venipuncture collection method.
Conclusion: These studies evaluate the feasibility and considerations for implementation of different low volume sampling technologies.
