This study developed a urine microsampling LC-MS/MS workflow for anti-doping analysis of glucocorticoids. Real microsamples agreed closely with liquid urine and showed strong linearity, extraction yield, precision, and limited matrix effects.
This study developed and validated an LC-MS/MS assay for vancomycin in 20 µL VAMS whole-blood samples. The method is being applied in an ongoing pediatric clinical study and demonstrated long-term dried-sample stability.
This study developed and validated a high-throughput LC-HRMS method for intact IGF-I in VAMS dried blood. The workflow showed promise for accurate, minimally invasive measurement in athlete anti-doping samples.
This study developed an LC-MS/MS assay for testosterone, androstenedione, and 17-hydroxyprogesterone in blood collected with Mitra devices. Finger-prick samples showed minimal bias for androstenedione and 17-hydroxyprogesterone compared with conventional measurements.
This study evaluated capillary volumetric microsampling for measuring central nervous system drugs and metabolites. The validated workflow supported accurate self- and home-sampling and may enable more patient-centered therapeutic drug monitoring.
This application note describes the use of VAMS devices with the Simoa SARS-CoV-2 IgG Antibody Test. Initial results demonstrated repeatability, correlation, and stability supporting remote, small-volume sample collection.
This study assessed Mitra microsampling for tacrolimus and creatinine monitoring in renal transplant patients. Results showed small biases versus standard assays and supported finger-prick microsampling as an alternative for home monitoring.
This review summarizes immune responses and immunopathological changes associated with COVID-19. While broader than microsampling, it may support COVID-related context for serology, immune monitoring, or related application areas.
This presentation examines metabolomics/lipidomics of dried blood spots using a novel blood microsampling device (hemaPEN®). No significant differences (p-values <0.05, fold change >1.5) were observed between biological/technical replicates (log transformed and median normalized data) demonstrating the intra- and inter- volumetric precision of the hemaPEN device.
This presentation examines implementation of Tecan® automation with neoteryx Mitra® volumetric absorptive microsampling (VAMS) for reagent preparation for an anti-drug antibody (ADA) assay. The poster will summarize the successful implementation of the Tecan® automation process with Mitra® VAMS tips, which demonstrated high concordance with data from manually processed VAMS.
