Urinary sediment red blood cells

Urine sediment (urinarysediment) examination is to examine the urine sediment by microscope, identify various pathological components such as cells, tubes, crystals, bacteria and parasites in urine; assist in diagnosis, localization and differential diagnosis of urinary system diseases. An important routine test item for prognosis judgment. Changes that cannot be found in general traits or chemical tests can often be found by sedimentation tests. Examination of red blood cells in urine sediment can be used to assist in the diagnosis of urinary system diseases, hemorrhagic diseases, collagen and allergic diseases, cardiovascular diseases, diseases of organs adjacent to the urinary system, and the like. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: normal. Normal value: Urine sediment red blood cells (centrifugal urine): 0-3HP Above normal: Erythrocytes are the most important component of urinary sediment. Adults can occasionally see one red blood cell every 4-7 high power fields. If 1-2 red blood cells are seen in each visual field, it should be considered as abnormal. If each high power field is visible, 3 More than one red blood cell, or diagnosed as microscopic hematuria. negative: Positive: Tips: Do not exercise vigorously, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. Women in menstruation are not suitable for this examination. Microscopy should be performed promptly after urine collection, otherwise it will affect the accuracy of the test. Normal value Mix a drop of urine 0 - occasionally / HP. Centrifuge urine 0-3/HP. (Note the specific reference value depends on each laboratory.) Clinical significance Abnormal result Erythrocytes are the most important component of urinary sediment. Adults can occasionally see one red blood cell every 4-7 high power fields. If 1-2 red blood cells are seen in each visual field, it should be considered as abnormal. If each high power field is visible, 3 More than one red blood cell, or diagnosed as microscopic hematuria. The person in need of testing has blood in the urine. High results may be diseases: acute cystitis, acute pyelonephritis precautions Before the test: prohibit strenuous exercise, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. At the time of examination: microscopy should be performed quickly after urine collection, otherwise the placement time is too long, if it is low urine, hemolysis can occur; if it is high urine, it may be dehydrated and the shape of red blood cells changes; if it is alkaline urine It can cause blood cell components and tube types to collapse, affecting the accuracy of the test. Inspection process The urine of the subject was collected, made into a slide, and observed under a microscope. Not suitable for the crowd Not suitable for the crowd: women in the menstrual period. Adverse reactions and risks No.
