While you're taking warfarin, you need regular blood tests to see if your dose of warfarin needs to be adjusted. These blood tests, which are called protime (PT) tests or International Normalized Ratio (INR) tests, or PT/INR for short, measure how fast your blood clots. If your PT/INR test result is too high, your risk of bleeding increases; if it's too low, your risk of getting a blood clot increases. Your doctor and other healthcare providers will decide what range of numbers are best for you. Your dose of warfarin will be adjusted from time to time to keep your PT/INR within that range.
