Urinary sediment leukocytes (WBC, LEU)

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. A change that cannot be found in a general trait test or a chemical test. Examination of leukocytes in urine sediment after centrifugation can be used to aid in the diagnosis of urinary tract infections and their early investigation. 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 white blood cells (male): 0-3/HP Urine sediment white blood cells (female): 0-5/HP Above normal: 1. In the urinary system, leukocytosis can be seen in the urine, especially in bacterial infections, such as acute and chronic pyelonephritis, cystitis, urethritis, prostatitis, kidney tuberculosis, etc.; if neutrophils appear in large numbers It is suspected that there is active bacterial infection in the kidney and urinary tract; it is considered to be pyelonephritis when coexisting with small round epithelial cells or caudate epithelial cells; cystitis is considered when coexisting with round epithelial cells; coexistence with squamous epithelial cells Consider urethritis or mixed with vaginal discharge. 2. Female vaginitis or cervicitis, annex inflammation can be due to secretions into the urine, and see leukocytosis, often accompanied by a large number of flat epithelial cells. 3. A large number of lymphocytes and monocytes can appear in the urine, which can be seen in the rejection reaction after kidney transplantation; lymphocytosis can also be seen in viral infections and lupus nephritis. 4. Increased mononuclear cells in urinary leukocytes can be seen in drug-induced acute interstitial nephritis and crescentic glomerulonephritis; mononuclear cells decrease or disappear during acute tubular necrosis. 5. The presence of a large number of eosinophils in the urine exceeding 5% of the total white blood cells is called eosinophilic urine, which can be seen in some patients with acute interstitial nephritis; drug-induced allergic reactions in other parts of the urinary tract such as urethritis Eosinophilic urine can also occur in non-specific inflammation. 6. Increased plasma cells in the urine, seen in myeloma. negative: Positive: Tips: Wash the vulva before leaving the urine. The container used should be clean and free of pollution. Do not mix chemicals such as detergents, disinfectants and preservatives to avoid affecting the inspection results. Women should prevent vaginal discharge from getting into the urine. Immediately after taking the urine, the test should be carried out to prevent the test result from being wrong after the urine is placed. Normal value Mix a drop of urine 0-1/HP. Centrifugal urine male 0-3/HP; female 0-5/HP. Clinical significance 1.

Increased plasma cells in the urine, seen in myeloma. High results may be diseases: chronic pyelonephritis, nephritis precautions 1. Wash the vulva before leaving the urine. The container used should be clean and free of pollution. Do not mix chemicals such as detergents, disinfectants and preservatives to avoid affecting the inspection results. 2, women should prevent vaginal discharge into the urine. 3, should be sent immediately after the urine, to avoid the test results are wrong after the urine is placed. Inspection process Add a drop of dye solution to 0.2 ml of urine sediment and mix and dye. After 3 minutes, take the sediment cover and take a slide of the slide. RESULTS: Red blood cells were stained with lavender, and the nuclei of polymorphonuclear leukocytes were stained orange-purple, and particles were visible in the pulp. The transparent tube is dyed orange-purple, the particles are visible in the slurry, the transparent tube is dyed pink or lavender, and the cell tube is dyed dark purple. Not suitable for the crowd Generally no taboos. Adverse reactions and risks No.
