Hi Ama Konadu:

Depending on your diagnosis and your physician, that will determine what your therapeutic goal range is for your PT/INR.  

For example, your doctor may want to keep your INR between 2.0-3.0 (this is a common range as well as, 2.5-3.5). So the office that is monitoring your lab work should notify what your PT/INR is. If you are within your therapeutic range that means your blood has a less chance of clotting and it is where your doctor wants it to be. If it is less than 2.0, it means your blood is too thick, which increases your chance of your blood clotting, so your doctor may increase your warfarin dose, or choose to monitor. If you lab is greater than 3.0, meaning your blood is too thin, your doctor may choose to lower your warfarin dose, hold your medication, monitor, or give you a different medication that can decrease your chance of bleeding too much. Your lab results and if there are any warfarin dose changes, that will help determine how frequently you need your lab drawn.

There are many things such as foods and medications that can effect your PT/INR levels. I recommend you visiting with your physician to get further information on the diet that you should eat. Also be sure to notify your physician if you have any medicaiton changes.

Take care,
