Overview
Hematuria is defined as the presence of red blood cells (RBCs) in the urine. Gross hematuria and microscopic hematuria( MH) are 2 types of hematuria. One of the most widely used definitions of microhematuria is the presence of at least two or three red blood cells per high power-field on a properly collected urinary specimen (confirmation should be done with 2 or 3 urinalyses) in the absence of an obvious benign cause (e.g. mild trauma or sexual activity preceding the collection).
Definition
Hematuria is defined as the presence of blood in the urine. Gross hematuria and microscopic hematuria( MH) are 2 types of hematuria .[1] Definitions for MH vary considerably and range between 1 to 10 red blood cells per high-power microscope field. [2] This difference is due to factors affecting related to sample collection and quantification. One of the most widely used definitions of MH is the presence of at least two or three red blood cells per high power-field on a properly collected urinary specimen (confirmation should be done with 2 or 3 urinalyses taken consecutively) in the absence of an obvious benign cause (e.g. mild trauma or sexual activity preceding the collection).[3][4]
