Objectives: Iron depletion is common around the world and among certain risk groups in developed countries. The overall purpose was to test the suitability of a novel plasma collection card for minimally invasive iron status assessment.
Methods: Twenty participants (10 f/10 m) participated in this cross-sectional study. Ferritin and hemoglobin were measured from blood collected from a forearm vein, serving as reference method. Blood was also collected from the fingertip using the NoviplexTM Plasma Prep Card as well as capillary collection tubes.
Results: There was substantial concordance between ferritin measured from samples collected via NoviplexTM and venous ferritin (concordance correlation …
