Development and validation of ivermectin quantification method in volumetric absorptive microsampling using liquid chromatography-tandem mass spectrometry
Harahap et al.
The finding, in our words
The authors validated a VAMS method for ivermectin therapeutic drug monitoring in whole blood, achieving a lower limit of quantification of 1 ng/mL and a linear range of 1–150 ng/mL. By eliminating haematocrit effects that limit dried blood spots, the method supports accurate decentralised sampling for antiparasitic therapy.

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.

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.

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.

A VAMS-LC-MS/MS method was developed and validated for measuring four antibiotics in 10 microlitres of human blood, showing that VAMS provided accurate quantification unaffected by haematocrit, unlike dried blood spots. The method was applied to paediatric patient samples, supporting its use for therapeutic drug monitoring in children.

An LC-MS/MS method for miltefosine quantification using VAMS was successfully validated, showing good accuracy within ±10.8% and precision below 11.9%. Although VAMS reduced haematocrit-induced bias compared to traditional dried blood spots, recovery still declined at higher haematocrit levels.
