Platelet disorders

Abstract

Platelets play a vital role in haemostasis; therefore, an increase or decrease in levels or a disorder of platelet function can lead to symptoms such as easy bruising and excessive bleeding, particularly from mucocutaneous sites. Patients may also report symptoms associated with the underlying condition. Platelet disorders pose a particular challenge for primary care, due to the vast array of potential causes and clinical outcomes, ranging from little effect to life-threatening problems. Initial assessment in primary care should aim to identify those requiring urgent investigation or treatment, while also determining an underlying cause and potential complications.
