Thrombotic microangiopathies

This group of diseases is characterized by systemic or intrarenal aggregation of platelets, thrombocytopenia, and mechanical injury to erythrocytes.

Test Strategy

Along with the well known routine laboratory parameters, measurement of factor H and metalloproteinases namely ADAMTS13 is recommended.

Pathogenesis

The pathogenetic link is the occlusion of microvessels by microthrombi. The resulting insufficient perfusion is responsible for the organ specific symptoms.
