Overview
Hematuria is defined as the presence of an abnormal quantity of red blood cells (RBCs) in the urine.[1]
Definition
Hematuria is defined as the presence of an abnormal quantity of red blood cells (RBCs) in the urine that may be visible to the naked eye (gross hematuria) or detectable on microscopic examination of the urine sediment (microscopic hematuria).[2] Definitions for MH vary considerably and range between 1 to 10 red blood cells per high-power field. [3] This difference is due to factors affecting related to sample collection and quantification. One of the the most widely used definition of MH is the presence of three or greater red blood cells per high power-field on a properly collected urinary specimen in the absence of an obvious benign cause (e.g. mild trauma or sexual activity preceding the collection).[4]
