Determination of Fluconazole in Children in Small Blood Volumes Using Volumetric Absorptive Microsampling (VAMS) and Isocratic High-Performance Liquid Chromatography-Ultraviolet (HPLC-UV) Detection
Zimbelmann et al.
The finding, in our words
This study validated a method for quantifying fluconazole using the Mitra device, demonstrating sufficient accuracy and precision for therapeutic drug monitoring in paediatric patients.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
The study developed and validated a rapid LC-MS/MS method for quantifying cefazolin in capillary whole blood collected via VAMS, plasma, and plasma ultrafiltrate, showing robust performance across matrices and successful application in a pediatric pilot cohort for therapeutic drug monitoring.

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 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.

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.

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.
