==Background==
*Thrombocytopenia is defined as platelets of less than 150 x 10<sup>3</sup>/mcL.  Symptoms such as bruising and petechiae usually occur at counts at 50 x 10<sup>3</sup>/mcL and between 5-10x 10<sup>3</sup>/mcL there is a high risk of spontaneous bleeding.

==Clinical Features==

*Nonpalpable [[petechiae]]/purpura
*Mucosal bleeding (gingival, [[epistaxis]])
*[[Vaginal Bleed Non-Pregnant|Menorrhagia]], [[hemoptysis]], [[hematuria]], [[rectal bleeding|hematochezia]]
*Deep tissue/joint bleeding is less common (more likely due to [[Coagulopathy (main)|coagulopathies]])

==Evaluation==

*Platelet count (CBC)
*Additional workup per clinical presentation

==Management==
Patient treatments are stratified by the presence or absence of bleeding and in the non bleeding patient by the platelet number and the presumed cause of the thrombocytopenia

{{Platelet transfusion indications}}

===Transfusion contraindications===
*[[TTP]], [[DIC]], [[HIT]]

===Pediatrics===
*1 unit of [[platelets]] per 5kg body weight raises count by 50k
