If you could get ADAMTS13 drawn at your home, for free, would you?


Yes! I wouldn't have to get a ride to the hematologist's clinic for the draw. I can't drive that far anymore due to my health conditions.


My issue is that the insurance company doesn't want to approve the testing unless my other blood work shows a problem.


One less trip to the hospital. One less anxiety event. One less PTSD trigger.

Fast, free, simple, and offered by a leader in ADAMTS13 testing
