Absolutely: Testing you INR is essential. Coumadin (warfarin) won't work if you INR is too low and you could be in danger of serious bleeding if it is too high.

Yes....: The only way to determine whether your dose of Coumadin (warfarin) is therapeutic is to check your pt/inr regularly. You need to be on therapeutic Coumadin (warfarin) to prevent recurrence of dvt/pe.
