Assessment of Dried Serum Spots (DSS) and Volumetric-Absorptive Microsampling (VAMS) Techniques in Therapeutic Drug Monitoring of (Val)Ganciclovir-Comparative Study in Analytical and Clinical Practice

Kocur et al.

The finding, in our words

The study developed and validated LC-MS/MS methods for ganciclovir in serum, dried serum spots, and VAMS-Mitra devices. In 80 pediatric renal transplant recipients, VAMS showed interchangeability with serum samples while extending stability to at least 49 days at room temperature, making decentralised therapeutic drug monitoring more feasible for transplant patients.

A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.

    Bioanalysis of six antibiotics from volumetric microsamples: a new tool for precision dosing in critically ill children

    A validated LC-MS method quantified multiple antibiotics from a single volumetric absorptive microsample, with stability up to 90 days for most analytes and minimal haematocrit effect except vancomycin, enabling pharmacokinetic and pharmacodynamic studies in decentralised settings.

    Developing a Method for Quantifying Meropenem in Children-Volumetric Adsorptive Microsampling Versus Plasma Sampling

    Volumetric absorptive microsampling of whole blood did not provide a reliable basis for calculating meropenem plasma concentrations in critically ill children, so a validated low volume plasma method was required for paediatric therapeutic drug monitoring.

    Microsampling Assays for Pharmacokinetic Analysis and Therapeutic Drug Monitoring of Antimicrobial Drugs in Children: A Critical Review

    This review summarises liquid chromatography with tandem mass spectrometry assays using dried blood spots and volumetric absorptive microsampling for quantifying antimicrobial drugs in children, highlighting that VAMS reduces haematocrit bias and offers a viable alternative to traditional plasma sampling for therapeutic drug monitoring.
