The following biomarkers are discussed: b-type natriuretic peptide (BNP), d-dimer, c-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), neutrophil–lymphocyte ratio (NLR), total cholesterol, triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and apolipoprotein A. Lastly, the structure of a point-of-care biosensor device is presented, as a measuring tool for stroke biomarkers on-site. This evidence concerns the gene IL6 and Stroke.
