Introduction of an electrochemical point‐of‐care assay for quantitative determination of paracetamol in finger‐prick capillary whole blood samples

Upward biases in POC compared with venous plasma HPLC-MS/MS were likely due to higher paracetamol concentrations in capillary blood than in venous plasma and to faulty individual sensors. The novel POC method is a promising tool for paracetamol concentration analysis.
