What Causes Lymphocytes in Urine?

Analysis of the results of routine urine tests is a matter of medical examination.

Analysis of urine routine test results

Purpose of analysis of inspection results:

1. Assist in the diagnosis of urinary system diseases and observation of effects: such as tuberculosis,

1,

The urine routine result is written on a piece of paper, which is called a urine routine test sheet. The indicators on the urine routine test list include: pH (pH), urine specific gravity (SG), urobilinogen (URO or UBG), occult blood (BLO), white blood cells (WBC), urine protein (PRO), urine sugar (GLU) , Bilirubin (BIL), ketone body (KET), urine red blood cells (RBC), urine color (GOL).

Routine urine tests are not only a common examination method for urinary system diseases, but also an auxiliary analysis tool for some other system diseases. Many patients often feel uncomfortable at the hospital

1. If the urine is stored in the bladder for too long, neutrophils may be destroyed, releasing esterase into the urine, resulting in a urine dry chemical test result that is positive for leukocytes, and a microscopic examination is negative. In this case, dry chemistry Analyzer inspection results shall prevail.

2. Renal transplantation patients' rejection reactions can cause a large number of lymphocytes in urine, lymphocytes have no esterase, and dry chemical analysis is negative for white blood cells. Microscopic examination has white blood cells. Microscopic examination shall prevail.

3. Kidney disease: The red blood cells in the urine are often destroyed to release hemoglobin. Therefore, there is no red blood cells in the microscopic examination. The dry chemical analysis is positive for hemoglobin (occult blood). At this time, the specimen is heated and boiled for 1 min. If it is not positive, the latter result shall prevail.

4. If red blood cells are found under the microscope and occult blood is negative for dry chemical analysis of urine, if the distilled water destruction test is positive, it may be a false negative due to the interference of reducing substances such as vitamin C, or the test strip is invalid. The results under the microscope should be quasi. ^[1]
