In lung and renal transplant recipients, VAMS sampling with LC-MS/MS quantification of mycophenolic acid and tacrolimus showed good linearity and accuracy, and with a haematocrit-adjusted conversion formula achieved clinical agreement in most samples; tacrolimus did not require haematocrit correction. The approach is virtually painless and enables richer sampling for more accurate drug exposure estimates, supporting decentralised therapeutic drug monitoring.

This study found that volumetric absorptive microsampling shows satisfactory agreement with venous plasma for monitoring several antiseizure medications in paediatric patients. However, a blood-to-plasma conversion factor was required to estimate plasma concentrations for clobazam and carbamazepine metabolites due to poor capillary-to-plasma interchangeability.

ALAS2 and CA1 mRNA were reliably quantified from venous-cellulose, capillary-cellulose and Tasso-M20 dried blood spots with strong linear agreement (r ≥ 0.96) and no bias for ALAS2. CA1 showed modest proportional bias of 9-22% only when Tasso-M20 was compared with cellulose cards in the rEPO cohort, but no significant differences in relative expression across matrices were observed at any timepoint. These findings support decentralised capillary sampling for longitudinal anti-doping monitoring.

In a cohort of 62 participants evaluating home self-collection with the TassoPlus device, 38 returned samples, with 29% excluded due to insufficient plasma volume below 200 ΔL. Although viral load measurements in adequate samples correlated well with conventional testing (r = 0.800), the high failure rate and missed detection in low-volume viremic samples indicate that further technical refinements are necessary before clinical adoption.
