I always test in the morning, seldom drink then.. Particularly when to test after having alcohol
Having alcohol in your blood makes no difference to the test accuracy but the effect of the body clearing the alcohol does choke down the disposal system (cytochrome p450) and results in a short term elevation of INR after drinking (a day or two). Its either minimal (meaning sub clinical significance) for a few drinks or notable (after a lot of drinks). Either way once you get the hang of it you may be the type to reduce your subsequent dose by (say) 10% to account for that and its all smoothed out.
