Wallet card that can be carried by patients with TTP

Patients with TTP can carry this wallet card and show it to emergency department personnel or clinicians who are not familiar with their diagnosis as a way to ensure that they convey the potential life-threatening severity of their disease and the importance of obtaining a CBC with platelet count, even for nonspecific symptoms that might herald a relapse. This may be especially important if they become confused and cannot adequately convey this information.
