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 Platelet Function Analyser-100 to predict bleed after percutaneous kidney biopsy. Platelet Function Analyser-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.
