If you have hemophilia (A or B) or von Willebrand disease (VWD) and use clotting factor replacement products, then talk to your health care provider about the chances of developing an inhibitor and about getting tested. Ask your health care provider about when you were tested last and how often they want you to get tested in the future.
Your health care provider might already do regular inhibitor tests but may not have mentioned these because you always had negative results.
If you don’t have insurance or your insurance won’t cover inhibitor testing there are options to receive testing for free, such as participating in a surveillance project called Community Counts.
To learn more about the specifics of inhibitor testing we invite you to visit the Facts About Inhibitors booklet, page 4.
