Evaluation of volumetric DBS for lead analysis using ICP-MS/MS: addressing matrix effects and hematocrit variability

BACKGROUND: Lead testing in dried blood spots (DBS) offer a convenient alternative to venous blood draw; however, its adoption has been limited by variable extraction efficiency, matrix effects, and hematocrit-dependent recovery. To mitigate these challenges, we explored the util...
