Introduction
Thrombocytopenia refers to relatively few platelets in blood. A normal platelet count ranges from 150,000 to 450,000 per microliter of blood, determined by the 2.5th lower percentile of the normal platelet count distribution.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
Common Causes
- Bone marrow suppression (for example chemotherapy, irradiation)
- Chronic alcohol use
- Chronic liver disease
- Congenital thrombocytopenia
- Disseminated intravascular coagulation
- Drug-induced thrombocytopenia
- Gestational thrombocytopenia
- HELLP syndrome
- Hemolytic uremic syndrome
- Heparin-induced thrombocytopenia
- Immune thrombocytopenic purpura
- Infections
- Preeclampsia
- Pseudothrombocytopenia
- Thrombotic thrombocytopenic purpura
Management
Shown below is an algorithm summarizing the approach to thrombocytopenia.
