A closer look
Guessing drug dosages based on body weight is an archaic game of medical Russian roulette. Precision dosing leverages your liver's specific genetic code to avoid disaster. The enzyme responsible for clearing the dangerous blood thinner Warfarin from your system is governed by the CYP2C9 gene. If a patient harbors a slow-metabolizer variant, a standard 'safe' dose will heavily accumulate in their blood, thinning it until they suffer a spontaneous and lethal hemorrhage.
