Part 4:  Long-term Treatment with Warfarin

Where do I go to have my PT or INR measured?

Usually a family doctor, internist, or other primary care provider will draw your blood and send it to a laboratory for analysis. Sometimes, you may be referred to a specialized anticoagulation clinic where monitoring is performed on site. At other times, especially in more complex cases, a hematologist will be involved, making recommendations and performing the necessary monitoring. When individuals live a long distance from a hematologist or specialized anticoagulation clinic, they may have their blood analyzed at a local hospital or laboratory and have the results faxed to their healthcare provider.
