This study compared self-collected capillary blood devices with plasma for N-glycosylation analysis. Volumetric and plasma-separation formats showed better comparability and repeatability than conventional DBS, supporting further validation in larger cohorts.
This study developed and validated an LC-MS/MS method for cocaine and its metabolites in capillary blood collected with hemaPEN. The device produced fixed-volume samples with acceptable performance and seven-day analyte stability.
This study developed and validated an LC-MS/MS assay for furosemide in 10 µL VAMS whole-blood samples. The method is being used to support pharmacokinetic research in a prospective pediatric clinical study.
This study developed a green LC-MS/MS method to quantify methotrexate polyglutamates across whole blood and separated blood-cell matrices collected by venipuncture or VAMS. The assay achieved acceptable accuracy and precision while improving analyte coverage and reducing environmental impact.
This article describes the design and baseline characteristics of the Smidt Heart Institute Takotsubo Registry. The registry provides a deeply phenotyped participant cohort to investigate disease mechanisms, identify treatment targets, and support future trials.
This study developed a population-based model using serial PEth measurements to assess alcohol abstinence. A two-step decision tree verified abstinence even above the standard decision limit, with reported sensitivity and specificity of 89%.
This study developed a UHPLC-HRMS workflow to screen 235 drugs in capillary blood and compared seven dried-blood microsampling devices. The validated method was fit for doping-control use and provided data complementary to urine testing.
This study developed an eight-plex immunoassay for measuring Group A Streptococcus antibody responses from small-volume samples. The assay supports serology and vaccine research, including feasibility with dried blood samples.
This study evaluated an automated workflow for measuring tacrolimus from VAMS devices using tandem mass spectrometry. The approach supports higher-throughput therapeutic drug monitoring from microsampled blood.
This study compared volumetric blood collection devices with conventional DBS cards for monitoring phenylalanine and tyrosine in phenylketonuria. Volumetric devices reduced several pre-analytical limitations, although device-specific biases remained important.
