Why is the urine routine white blood cell count 2

A routine urine test is an effective way to analyze and understand whether you are infected with certain diseases. Some people's test results are positive, while others are negative. However, a positive result does not necessarily mean a serious disease problem. Therefore, we must learn to recognize some reports of routine urine tests. Let's learn how to understand routine urine test reports.

1. Routine urine analysis is a test we often do. Most hospitals use urine analyzers for testing. There are currently 10, 11 or 12 test items, and the report format is not uniform. It contains both "+" (positive), "-" (negative), and numbers, and the units of the test items are also different.

2. Kidney disease items, acidity and alkalinity (pH), specific gravity (SG), occult blood or red blood cells (BLD, ERY), protein (PRO) and color (COL). The normal reference values ​​are: 4.6-8.0, 1.005-1.030, positive, negative, light yellow to dark yellow. Changes in these indicators may indicate renal impairment.

3. Diabetes items, acidity and alkalinity (pH), protein, specific gravity, sugar (GLU) and ketone bodies (KET). The detection of these indicators helps to diagnose related complications and whether some organs of the body are damaged, such as whether ketonemia occurs. Under normal circumstances, urine sugar and ketone bodies are negative.

4. Urinary tract infection items: white blood cells (WBC), occult blood or red blood cells, nitrite (NIT), color and turbidity (TUR). When the urinary system is infected with bacteria, white blood cells and red blood cells often appear in the urine, the color or turbidity of the urine also changes, and nitrite is sometimes positive. Chemical testing of urine white blood cells and occult blood or red blood cells only serves as a screening method, and the clinical diagnosis is based on the results of microscopic examination.

5. Other disease-related items, mainly pH, specific gravity, bilirubin (BIL), urobilinogen (URO), color and other indicators. The two indicators of bilirubin and urobilinogen reflect the ability and amount of the liver to metabolize hemoglobin. Under normal circumstances, urine bilirubin is negative and urobilinogen is weakly positive. When the above indicators increase, it often indicates jaundice and the urine becomes yellow-green in color.
