Platelet storage pool deficiency is a type of coagulopathy characterized by defects in the granules in platelets, particularly a lack of granular non-metabolic ADP.[3] Individuals with ADP deficient storage pool disease present a prolonged bleeding time due to impaired aggregation response to fibrillar collagen.[citation needed]

Symptoms and signs[edit]


The presentation (signs/symptoms) of an individual with platelet storage pool deficiency is as follows:[1]


Hairy cell leukemia

The condition of platelet storage pool deficiency can be acquired or inherited(genetically passed on from the individuals parents[4]).[1]Some of the causes of platelet storage pool deficiency when acquired are:[1]


Platelet structure

In terms of the pathophysiology of platelet storage pool deficiency one must consider several factors including the human body's normal function prior to such a deficiency, such as platelet alpha-granules[citation needed] one of three types of platelet secretory granule[5]

Platelet α–granules are important in platelet activity, α–granules connect with plasma membrane.This in turn increases the size of the platelet. Platelet α–granules have an important role in hemostasis as well as thrombosis.SNARE accessory proteins control the secretion of α–granule.[5]


The diagnosis of this condition can be done via the following:[1]


This condition may involve the alpha granules or the dense granules.[6] Therefore the following examples include:

Flow cytometry analysis


Platelet storage pool deficiency has no treatment however management consists of antifibrinolytic medications if the individual has unusual bleeding event, additionally caution should be taken with usage of NSAIDS[1][2]
