HI Judy,
It's advised to get your INR done early enough in the day for your doctor to receive the results and call you before their office closes. Many people ask their doctors for a STAT requisision to take in to the lab every time. That way, you're guaranteed to get your results back same day. It doesn't help you one bit to get the results back the next day because you have to take a dose before bed. You need to know if your dose needs a change or not.
So taking your coumadin with your bedtime meds is the best way to go.
Here in Canada, a stat test can be entered into the computer system so you don't need a piece of paper every time you go in. If you need a paper every time, just make a wack of copies of the original!
Good luck on Monday! I have to go that day too!
