[[Thrombocytopenia]] has a broad range of potential causes. While a good [[History and Physical examination|history and physical examination]] can be helpful to diagnose some of these causes such as drug-induced thrombocytopenia, they usually don't suffice and further evaluation is often needed. There are also some useful points that may guide the [[physician]] to an appropriate [[diagnosis]]. For example, [[asymptomatic]], isolated [[thrombocytopenia]] most probably suggests [[Idiopathic thrombocytopenic purpura|ITP]], while [[thrombocytopenia]] in critically ill, hospitalized patients is usually suggestive of [[Iatrogenesis|iatrogenic]] causes (eg. [[dilution]]), [[platelet]] consumption, [[bone marrow suppression]] from [[infection]]/[[sepsis]], or even [[drug-induced thrombocytopenia]]. One should consider however, that a wide variety of other conditions such as [[autoimmune disorders]], [[nutrient]] deficiencies, [[thrombotic microangiopathies]] could all as well cause [[thrombocytopenia]]. | [[Thrombocytopenia]] has a broad range of potential causes.

Overview
Thrombocytopenia has a broad range of potential causes. While a good history and physical examination can be helpful to diagnose some of these causes such as drug-induced thrombocytopenia, they usually don't suffice and further evaluation is often needed. There are also some useful points that may guide the physician to an appropriate diagnosis. For example, asymptomatic, isolated thrombocytopenia most probably suggests ITP, while thrombocytopenia in critically ill, hospitalized patients is usually suggestive of iatrogenic causes (eg. dilution), platelet consumption, bone marrow suppression from infection/sepsis, or even drug-induced thrombocytopenia. One should consider however, that a wide variety of other conditions such as autoimmune disorders, nutrient deficiencies, thrombotic microangiopathies could all as well cause thrombocytopenia.
