the result is .36 mmol/l, which converts to 5 mg/dl, and is considered to be low for somebody taking aspirin in a serious dose for something like arthritis (which is what the test is designed for. so, it says i'm low because it's low for an arthritis patient on rx strength aspirin), but about on par with somebody taking something like a half an aspirin as a daily blood thinner. so, if you want the effects of aspirin without actually taking aspirin, try a diet high in fruits and spices - it's not hyperbole, i just measured it.
