This cross-validation study compared VAMS and venous tacrolimus measurements in pediatric solid-organ transplant recipients. The methods showed close agreement before and after dosing, supporting the feasibility of home-based tacrolimus monitoring for children.
Researchers developed VAMS–LC-MS/MS methods for phosphatidylethanol, a direct marker of alcohol intake, and compared results between two laboratories. The final methods were reproducible and closely aligned, while the work identified calibration and transition-selection issues important for broader standardization.
Researchers developed a high-throughput microfluidic nanoimmunoassay for SARS-CoV-2 antibodies and paired it with ultralow-volume finger-prick collection. The platform achieved high sensitivity and specificity while using minimal reagent, supporting decentralized serology and broader protein-biomarker testing.
This review evaluates published applications of Mitra VAMS for therapeutic monitoring of antiseizure medications. It highlights minimally invasive home collection and reduced hematocrit effects while noting that stability and performance remain drug-specific.
This article reports lessons from rapidly launching nationwide internet-based randomized clinical trials during the COVID-19 pandemic. Online screening, enrollment, outcomes, and follow-up enabled recruitment of 2,795 participants and informed recommendations for future remote trials.
This study evaluated a sensitive immunoassay for SARS-CoV-2 nucleocapsid protein in venous and capillary blood and saliva. The assay showed strong agreement with molecular testing early in infection and may support swab-free at-home or point-of-care collection.
This study standardized a highly specific SARS-CoV-2 ELISA protocol using conventional serum and mail-in dried-blood samples. Validation showed minimal cross-reactivity and supported reliable population measurement of infection, seropositivity, and immunity.
This review examines dried blood spots and newer microsampling approaches for therapeutic monitoring of monoclonal antibodies used in inflammatory disease. Home sampling offers practical advantages, but hematocrit and clinical validation remain important barriers to routine adoption.
This proof-of-concept study compared VAMS, dried blood spots, and fluid blood for untargeted lipid profiling by high-resolution LC-MS/MS. VAMS captured a broad lipid profile and appeared viable for lipidomics, although further characterization is needed.
This study developed multiplex antibody assays using SARS-CoV-2 and seasonal-coronavirus antigens to distinguish vaccination, natural infection, and cross-reactive immunity. The antigen-dependent assays achieved high sensitivity and specificity and may support surveillance as vaccination becomes widespread.
