Does An Abnormal PFA 100 Predict Bleeding After Renal Biopsy?
This study is currently recruiting participants.
Verified by University of Mississippi Medical Center, November 2008
Sponsored by: University of Mississippi Medical Center
Information provided by: University of Mississippi Medical Center
ClinicalTrials.gov Identifier: NCT00334204
  Purpose

-The kidneys are highly vascular organs and any trauma or surgery poses risk of severe bleeding. Platelet function is an integral part of the blood clotting during the initial, so-called vascular phase. So far no universally accepted, easy test has been available to measure platelet functions. Renal failure is a condition generally associated with bleeding due to platelet dysfunctions. This study is exploring the utility of a novel platelet function test, called PFA-100 to predict bleed after percutaneous kidney biopsy. PFA-100 will be measure before kidney biopsy along with routine blood tests. Subjects will undergo renal ultrasound before and after renal biopsy to verify post-biopsy bleeding events.
