Affecting approximately 1.7 to 14.5 per million people annually, thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening blood disorder characterized by widespread blood clot formation in small vessels. Understanding **what is thrombotic thrombocytopenia** is critical for recognizing its urgent symptoms and seeking prompt medical care.

While Immune Thrombocytopenia (ITP) is officially classified as a rare disease, precise figures on its prevalence and incidence can vary depending on the population studied. In the United States, for example, the prevalence is estimated to be around 9.5 cases per 100,000 people.

Affecting as few as one in several million people, Factor XIII deficiency is an example of a truly rare blood disorder. These conditions often involve complex issues with the bone marrow, blood cells, or clotting proteins, posing significant diagnostic challenges.
