Urinalysis

Urine test is also called urine analysis (uninalyoio) is defined as visual, science, chemistry, microscope and instrument. The urine is analyzed to prevent, diagnose and diagnose the urinary, circulatory, liver, gallbladder and endocrine diseases. Wait for the purpose. Urine routine examination is a mandatory item in a health checkup. It is a general screening project for urine analysis, including color, turbidity, dry chemical test strips and sediment microscopy. Through this examination, the corresponding symptoms can be judged. 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: White blood cells and red blood cells do not appear in the urine. The urine color is yellow or dark yellow, the turbidity is clear, and the nitrite is negative. Urinary bilirubin is negative Positive: Urobilinogen is weakly positive Tips: Do not eat after 9:00 pm the day before the test. Drink water. Check the morning after getting up and do not eat or drink water, which is convenient for inspection. Female patients should not take urine for examination during menstruation. Normal value Under normal circumstances, urine sugar and ketone bodies are negative. White blood cells and red blood cells do not appear in the urine. The urine color is yellow or dark yellow, the turbidity is clear, and the nitrite is negative. Urinary bilirubin was negative, and urinary biliary was weakly positive. Clinical significance Abnormal results: 1. Diabetes projects. pH (pH), protein, specific gravity, sugar (GLU) and ketone body (KET). The detection of these indicators can help to diagnose related complications and damage to some organs of the body, such as the presence of ketosis. Under normal circumstances, urine sugar and ketone bodies are negative. 2. Urinary infections. 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, urine color or turbidity also changes, and nitrite is sometimes positive. Chemical detection of leukocytic cells and occult blood or red blood cells only play a screening role, the clinical diagnosis is based on the results of microscopic examination. 3. Other disease items. Mainly pH, specific gravity, bilirubin (BIL), urinary biliary (URO), color and other indicators. Both bilirubin and urobilinogen reflect the ability and quantity of the liver to metabolize hemoglobin. Under normal circumstances, urinary bilirubin is negative, and urinary biliary is weakly positive. When the above indicators increase, it often prompts jaundice, and the urine color is yellow-green. People who need to be examined: patients with nephritis, urine routine. Precautions Taboo before the test: Do not eat after 9:00 pm the day before the test. Drink water.
