Also known as Eddie Addis count, it is one of the quantitative examination of urine sediment, is to measure red blood cells, white blood cells and casts in concentrated urine at night for 12 hours, can understand the nature and severity of urinary system lesions, observe the efficacy and judge the prognosis. Specimen collection method: the patient should drink less water 24 hours before the examination, check the normal diet on the day, but the amount of liquid in the dinner should be less than 200 ml, so that the urine is properly concentrated.

Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Tips: Female patients should wash the vulva before urinating, to avoid cells in the vagina mixed into the urine. Normal value Tube type <5,000 (for transparent tube type), red blood cells <500,000, white blood cells (including epithelial cells) <1 million. Clinical significance Abnormal results Urinary tract infections and prostatitis often increase the number of white blood cells; nephritis often has a significant increase in red blood cells and casts. If white blood cells are found to be significantly more abundant than red blood cells and the number of white blood cells exceeds 1 million, it is helpful for the diagnosis of chronic pyelonephritis, which can be distinguished from chronic nephritis or hypertensive nephropathy. Patients with urinary tract infections, prostatitis patients, nephritis patients, and patients with pyelonephritis need to be examined. High results may be diseases: glomerulonephritis, urinary tract infections Unsuitable for the crowd: Female patients should wash the vulva before urinating to avoid mixing the cells in the vagina into the urine.

The total urine volume does not exceed 500 ml. Requirements for examination: urinating at 8 pm (empty bladder), then all urine from 8 pm to 8 am. To prevent damage to the formed components in the urine, preservatives should be added. Preservatives were added after the first urine collection, and the ratio was 0.5 ml of formalin per 100 ml. Do not overdose formalin, otherwise it will produce formaldehyde-urea complex precipitation, interference count. Inspection process Specimen collection method: the patient should drink less water 24 hours before the examination, check the normal diet on the day, but the amount of liquid in the dinner should be less than 200 ml, so that the urine is properly concentrated.
