Overview

Hematuria is defined as the presence of red blood cells (RBCs) in the urine.[1]

Definition

Hematuria is defined as the presence of RBCs in the urine. Gross hematuria and microscopic hematuria( MH) are 2 types of hematuria .[2] Definitions for MH varies considerably and range between 1 to 10 red blood cells per high-power microscope 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]
