Urine sediment 12 hour count

The Eddie Count was proposed by Addis in 1948 to quantify the amount of organic precipitates such as casts, red blood cells, and white blood cells in concentrated urine at night for 12 hours to understand the extent of kidney damage. The 12-hour urinary sediment count is a test method for examining the number of red blood cells, white blood cells, and casts excreted in the urine at 12 hours during the night to understand the extent of renal damage and urinary tract disorders and the evolution of the condition. It is often used for patients with suspected and atypical urine sediment microscopy, which plays an important role in diagnosis and differential diagnosis. Basic Information Specialist classification: male examination check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: normal. Normal value: Red blood cells: 0-50 million / 12h White blood cells: 0-100,000/12h Transparent tube type: 0-50 million / 12h Above normal: Urine white blood cells such as urinary tract infection and prostatitis are significantly increased; the number of urinary cells and casts in patients with various types of nephritis is slightly or significantly increased, red blood cells can reach 15 million to 400 million / 12h, and white blood cells can reach (2000 to 5000) /12h, tube type can reach (5 ~ 100) million / 12h urine. In patients with pyelonephritis, the increase in urinary cells is more pronounced. negative: Positive: Tips: Keep urine from 8:00 pm to 8:12 am the next day, and accurately measure urine volume and urine specific gravity. Normal value Red blood cells <500,000 / 12h. White blood cells <1 million / 12h. Transparent tube type <5000/12h. Clinical significance Urine white blood cells such as urinary tract infection and prostatitis are significantly increased; the number of urinary cells and casts in patients with various types of nephritis is slightly or significantly increased, red blood cells can reach 15 million to 400 million / 12h, and white blood cells can reach (2000 to 5000) /12h, tube type can reach (5 ~ 100) million / 12h urine. In patients with pyelonephritis, the increase in urinary cells is more pronounced. High results may be diseases: prostatitis, urinary tract infections (1) Collect 12 hours of urine in a clean container, add 10% formaldehyde preservative according to the ratio of 0.5% urine. (2) Before taking urine, fully mix the total urine volume for 12 hours before testing. (3) Before the test, the patient should be explained in detail about the method of specimen retention. It is forbidden to drink too much water, the urine volume should not exceed 500ml, the specific gravity should be between 1.026 and 1.035, and the proportion should be too low. (4) Salt crystals are likely to interfere with this test, and the test should be carried out after removing the crystals. (5) The urine retention time is longer in this test. When the room temperature is high, the cells or tube type are easily dissolved, and the urine sediment count is used for one hour. Inspection process (1) Urine is taken from 8:00 pm to 8:12 am the next day, and the urine volume and urine specific gravity are accurately measured. (2) Accurately absorb 10 ml of mixed urine, centrifuge in a centrifuge tube for 10 min at 1500 r/min, discard 9 ml of the supernatant, and mix well the remaining 1 ml. (3) Aspirate 1 small drop of mixed urine sediment in the blood cell counting tray, count the number of cells in 10 large squares and the number of tubes in 20 large squares, and calculate the cells and casts in the nighttime 12 hours. number. Not suitable for the crowd Generally no taboos. Adverse reactions and risks No.
