How can you prepare for a prothrombin time test?

ANSWER

Typically, you don’t need to do anything special. Some foods -- such as liver, broccoli, chickpeas, green tea, kale, turnip greens, and foods made from soy -- can affect your results. If you need to avoid certain foods or drinks, your doctor will tell you ahead of time. Make sure to let your doctor know about any medicines, vitamins, herbs, or supplements you take. That includes over-the-counter, prescription, or illegal drugs. Many medications, from aspirin to steroids, can affect your results. Also, if you’re on warfarin, you typically want to get the test before you take your dose for the day.
