Abstract Hemoglobin A1c (HbA1c) testing is critical for diabetes diagnosis and monitoring. Although many studies have demonstrated the feasibility of measuring HbA1c from dried blood spots (DBS) using immunoassays, enzymatic assays, certain high-performance liquid chromatography (HPLC) there limited evidence supporting use Bio-Rad D100 HPLC method. We evaluated DBS to support assessment glycemi...

Metabolomics and lipidomics techniques are capable of comprehensively measuring hundreds to thousands small molecules in single analytical runs have been used characterize responses exercise traditionally using venipuncture-produced liquid samples. Advanced microsampling devices offer an alternative by circumventing the requirement maintain frozen This approach combines a microneedle puncture f...

The preferred sampling medium for measuring human exposures of persistent organic compounds (POPs) is blood, and relevant sample types include whole blood, plasma, and dried blood spots (DBS). Because information regarding the performance and comparability of measurements across these sample types is limited, it is difficult to compare across studies. This study evaluates the performance of POP...
