This study compared anti-SARS-CoV-2 antibody results from home-collected dried blood with conventional venous samples using an electrochemiluminescence immunoassay. The methods showed comparable performance, and repeat testing indicated persistent antibodies up to ten months after infection.
This study developed a VAMS–LC-HRMS/MS method to monitor adherence to ten commonly prescribed antihypertensive drugs. The workflow was successfully validated for most analytes and performed consistently across hematocrit levels.
This study developed LC-MS/MS methods to assess thiamine status in dried VAMS and liquid blood. Comparable results and successful testing in healthy volunteers supported the method’s validity for patient-centric nutritional assessment.
This study developed and evaluated a VAMS-based method for measuring 13 frequently prescribed antipsychotics in finger-prick blood. The workflow was successfully validated for most analytes across multiple hematocrit levels and supported adherence monitoring.
This study compared thiamine measurements from capillary and venous VAMS samples with conventional liquid blood. The methods showed strong agreement, supporting one-drop finger-prick VAMS as a reliable patient-centric tool for assessing thiamine status.
This study developed and validated an HPLC-PDA method for hydroxychloroquine measurement in VAMS samples. The method met FDA validation criteria across a 2–6500 ng/mL calibration range, supporting therapeutic drug monitoring.
This application note describes purification of total RNA, including miRNA, from whole blood collected on Mitra microsamplers using the Maxwell RSC miRNA Plasma and Serum Kit and Maxwell RSC Instrument.
This method development study quantified several opioids and metabolites in plasma, whole blood, and VAMS-collected blood. Results support accurate LC-MS/MS analysis across matrices, including whole blood collected using VAMS.
This presentation explores a universal bioanalytical workflow for VAMS samples. Continuous polarity switching supported a single-assay approach in place of separate positive- and negative-ionization workflows.
This presentation examines quantitation of the monoclonal antibody rituximab using VAMS, impact-assisted extraction, trypsin digestion and LC-MRM. The developed assay demonstrated excellent linearity, precision and accuracy whilst negating hematocrit effect.
