Thrombocytopenia Differential Diagnosis

Thrombocytopenia Differential Diagnosis:

Thrombocytopenia is the medical term for a low blood platelet count. Platelets (thrombocytes) play an important role in blood clotting. Platelets stop blood loss by clumping and forming plugs in blood vessel holes. Thrombocytopenia often occurs as a result of a separate disorder, such as leukemia or an immune system problem, or even due to some medication side effect. It may be mild and cause few signs or symptoms. In rare cases, the number of platelets may be so low that dangerous internal bleeding can occur.
