Clopidogrel dosing guided by platelet function assays helps achieve platelet inhibition in carriers of the CYP2C19*2 allele. Graphs show individuals who received additional clopidogrel loading doses (LD) if their post-clopidogrel platelet function remained elevated (according to the VASP assay), up to a total of 4 loading doses. Charts summarize the percentage of patients with elevated VASP index after the 1^st and 4^th loading doses (if needed). Adapted from²⁰.
