Urine white blood cells (WBC, LEU)

Detection of white blood cells in the urine helps early detection and auxiliary diagnosis of urinary tract infections, and is used for physical examinations of healthy people and those with urinary pain and abnormal urine. The white blood cells in the fresh urine are intact, mainly neutrophils, and may also have lymphocytes and monocytes. The neutrophils that are destroyed or killed during the inflammatory process are irregular in shape, have a faint structure, and are easily aggregated into pus cells. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: 1. Urine leukocytosis can be seen in glomerulonephritis, early postoperative renal transplantation, diseases of adjacent organs and tissues of the genitourinary system. 2. A large increase in white blood cells in the urine can be seen in urinary system inflammation, such as pyelonephritis, cystitis, urethritis, kidney tuberculosis, prostatitis, etc. 3. Pyuria indicates that the urinary system or its adjacent organs have infectious lesions, found in acute or chronic pyelonephritis, cystitis, urethritis, multiple renal abscesses, renal abscesses (concurrent to stones or stagnant water), kidney tuberculosis, mold or parasitic Insect infection. Acute glomerulonephritis can also occur in short-term leukocyteuria with mildly increased white blood cells, which is caused by immune inflammation. 4. When there is inflammation in the reproductive system of adult women, vaginal secretions are often mixed into the urine. It is characterized by the fact that in addition to the group of pus cells, a large number of squamous epithelial cells are also seen, which should be distinguished from urinary inflammation. Tips: Fresh morning urine should be used as much as possible. The urine that is randomly selected is preferably mid-stage urine. Women should avoid menstruation when taking urine specimens and should prevent vaginal secretions from mixing into the urine. Normal value There may be a small amount, which is (-) ~ (++). Male 1 to 2 or less / 10HP; Female 1 to 2 or less / HP. The precipitate was centrifuged <5/HP. The reagent strip method was negative (10 or less/mm3). (Note the specific reference value depends on each laboratory.) Clinical significance Detection of white blood cells in the urine helps early detection and auxiliary diagnosis of urinary tract infections, and is used for physical examinations of healthy people and those with urinary pain and abnormal urine. The white blood cells in the fresh urine are intact, mainly neutrophils, and may also have lymphocytes and monocytes. The neutrophils that are destroyed or killed during the inflammatory process are irregular in shape, have a faint structure, and are easily aggregated into pus cells. More than 5 urine cells per white microscope at high magnification are called pyuria. 1. Urine leukocytosis can be seen in glomerulonephritis, early postoperative renal transplantation, diseases of adjacent organs and tissues of the genitourinary system. Within 1 week after renal transplantation, more neutrophils may appear in the urine, which may then gradually decrease and return to normal. In the case of rejection, a large number of lymphocytes and monocytes are seen in the urine. 2, a large number of white blood cells in the urine, can be seen in the inflammation of the urinary system, such as pyelonephritis, cystitis, urethritis, kidney tuberculosis, prostatitis. 3, pyuria indicates that the urinary system or its adjacent organs have infectious lesions, seen in acute or chronic pyelonephritis, cystitis, urethritis, multiple renal abscesses, renal abscesses (concurrent to stones or stagnant water), kidney tuberculosis, mold or parasitic Insect infection. Acute glomerulonephritis can also occur in short-term leukocyteuria with mildly increased white blood cells, which is caused by immune inflammation. 4. When there is inflammation in the reproductive system of adult women, vaginal secretions are often mixed into the urine. It is characterized by the fact that in addition to the group of pus cells, a large number of squamous epithelial cells are also seen, which should be distinguished from urinary inflammation. 5, white blood cell urine combined with other inspection items reference application (1) Generally in the case of urinary tract infection, it is common to 1 (5) or more of urinary sediment; 2 nitrite (+); 3 urinary bacteria culture above 100,000/ml; 4 urine pH is usually alkaline (candida) Except for infection). (2) When obvious white blood cell urine, it is advisable to perform two cups of urine test for the first cup of turbidity for urethral inflammation, or for mixing from the genital area; the second cup of urine turbidity for inflammation of the bladder and prostate; two cups of urine are turbid for kidney Inflammation of the ureter and bladder. (3) Analysis of urinary bacterial culture results 1 White blood cells (+), bacteria (-) for aseptic leukocyte urine, first suspected tuberculosis, chlamydia, urinary mycoplasma and viral infection; in addition should consider allergic diseases, connective tissue Inflammation caused by disease, drug poisoning, radiation exposure; 2 white blood cells (-), bacteria (+), considered as asymptomatic bacterial urine, mixing and reproduction of genital parasites, and strong alkaline urine (proteobacteria infection) ). In the case of clinical suspected urinary tract infection and microscopic examination of white blood cells, it may be the cause of cell rupture. At this time, urinary leukocytes can still be detected by the reagent strip method. This is a special advantage of the white blood cell reagent strip method. Positive results may be diseases: precautions for urinary infections Note when checking: 1. Try to use fresh morning urine when doing this test. The urine that is randomly selected is preferably mid-stage urine. 2, women should avoid the menstrual period when taking urine specimens, should prevent vaginal secretions mixed into the urine, middle-stage urine is appropriate. 3. Use a clean and dry container for urine. It is better to use disposable urine cups and urine tubes provided by the hospital. The amount of urine used for routine testing should be about 10 ml and sent for inspection as soon as possible. Inspection process Inspection method: urine test. Not suitable for the crowd Menstrual women. Adverse reactions and risks no.
