First, the definition of hematuria Healthy people, such as taking fresh urine 10 ml, after centrifugation and sediment taken under a microscope examination, each high power field should not exceed 3 red blood cells. If three or more red blood cells are found in each high power field of the microscope, it is called “microscopic hematuria.” Some laboratories use the “+” to indicate the degree of microscopic hematuria, each high power field has 3 to 5 red blood cells +; 6 to 20 to ++; 21 to 50 to +++; 100+ Or full horizon as ++++.
