If you’re on warfarin you may be interested in the 20 multiple choice question OAK test (Oral Anticoagulation Knowledge test). It was developed in Maryland, US in 2006 by Zeolla. It was validated in the US and later in Malaysia, which means it is a trustworthy test for finding out how much people understand about taking warfarin.
The pass score is 15 or more out of 20. You may like to see if you can beat the average mark which was 12/20 with 64% of people failing the test.

Paul’s comments on the test
How did you do? Angela insisted I take the test and fortunately I scored 100%. The test is good as it helps to remind you about some of the key things you need to know. It covers interactions with food and other drugs and reminds you about what the INR test means. Some of the questions are easy but a few make you stop and think just to keep you on your toes. Perhaps you should ask other members of your family if they can do it too?
