1. If I have genetic testing done, will I still need to be monitored with PT/INR tests?
Yes. Regardless of your genetic makeup, your response to warfarin therapy will still need to be monitored with regular PT/INR tests. This is because your individual degree of anticoagulation ("blood-thinning") can be affected by other factors such as diet, age, weight, other medications and state of health, which can change over time.
2. Can warfarin sensitivity testing be done in my doctor's office?
No, it requires specialized equipment to perform and expertise to interpret. It is not offered by every laboratory and may need to be sent to a laboratory outside of your hospital (i.e., reference laboratory).
4. Should I tell other doctors about my warfarin sensitivity?
Yes, and you should always tell them that you are taking warfarin. The use of warfarin and your sensitivity to warfarin is important information for the medical professionals (including dentists) that you see. It can have an effect on your treatment options.
5. Should my other family members be tested for warfarin sensitivity?
This is something to discuss with your healthcare provider and family. It is not generally indicated unless a family member is also going to be taking warfarin, but having a family member who has warfarin sensitivity is important information to keep in mind and to share with your health practitioner.
