Self-sampling of capillary blood for safety monitoring of DMARD therapy in patients with rheumatic disease: a feasibility and method-comparison study.

Our study aimed to compare the quality of patient self-collected capillary samples with venous blood samples. Additionally, we assessed whether patients with rheumatic disease are both capable of and willing to perform capillary self-sampling through subjective and objective assessments. This research explores the future potential of at-home self-sampling.
