EDTA Pseudothrombocytopenia in Pre-Eclamptic Patient

Document Type

Conference Proceeding

Publication Date



EDTA pseudothrombocytopenia is a rare, under-recognized laboratory disease that causes concerns including delays in treatments, surgeries, and unnecessary platelet infusions. This little known phenomenon results in falsely low platelet counts due to platelets clumping together when drawing labs. Our case presents a 29-year-old female (G7P4024) at 34 weeks gestation with preeclampsia with severe features who was unable to have their platelet count accurately determined prior to performing anesthesia due to having EDTA pseudothrombocytopenia. We will discuss the pathophysiology of EDTA pseudothrombocytopenia and propose an algorithm of how to manage OB patients with this condition who require neuraxial or general anesthesia.
