ITP (immune thrombocytopenia) is an autoimmune condition that causes a low platelet count. Platelets are a type of blood cell needed to form a blood clot after a cut or injury to prevent bleeding and bruising. In ITP, your body’s immune system mistakenly targets platelets and starts to break them down. Fewer platelets are also made by the body. This results in lower numbers of circulating platelets.
