Urinary Infection Routine

Urinary infections Urinary routines are an auxiliary test used to check for urinary tract infections. Urinary infections such as urine routine indicators are 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. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting 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. Normal value 1, urinary white blood cells (U-LEU) normal people have a small number of white blood cells in the urine, centrifugal urine does not exceed 5 per high power field of view. The normal reference value is <5/HP. 2. The normal reference value of urinary nitrite (NIT) is negative (-). 3, occult blood (U-BLO) normal people can occasionally see red blood cells in the urine, after centrifugation and sedimentation, the field of view per high power microscope does not exceed 3. The normal reference value is negative (-). 4. The normal reference value of urinary nitrite (NIT) is negative (-). Clinical significance Abnormal results: 1, urinary white blood cells (U-LEU). When abnormal, the urine contains a large number of white blood cells, indicating purulent lesions in the urinary tract, such as pyelonephritis, cystitis and urethritis. Increased in acute 'tooth nephritis, pyelonephritis, bladder inflammation, urethritis, urethra tuberculosis and so on. 2. Urine nitrite (NIT). Positive, seen in bladder inflammation, pyelonephritis and so on. 3, occult blood (U-BLO). The presence of a large number of red blood cells in the urine may be caused by kidney bleeding, urinary tract bleeding, and renal congestion. Strenuous exercise and blood circulation disorders can also lead to increased glomerular permeability, while protein and red blood cells appear in the urine. Also seen in urinary calculi, infections, tumors, acute and chronic nephritis, thrombocytopenic purple cancer, hemophilia and so on. 4. Urinary bilirubin (U-BIL). Positive, seen in cholelithiasis, biliary tract tumors, biliary tract mites, pancreatic head cancer and other obstructive jaundice and liver cancer, liver cirrhosis, acute and chronic hepatitis, hepatocyte necrosis and other liver cell jaundice. People who need to be examined have abnormal urinary system. 5. Urine nitrite (NIT). Positive, seen in bladder inflammation, pyelonephritis and so on. Precautions Taboo before the test: 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. Requirements for inspection: 1. When urine is routinely examined, remove no less than 10 ml of urine. 2, generally require women to avoid urine during the menstrual period to prevent vaginal secretions mixed into the urine, affecting the results of the examination. 3, it is best to take the middle section of urine. 4, to use the urine should use a clean and dry container, that is, the disposable urine cup and urine test tube provided by the hospital. 5, the urine should be sent to the laboratory as soon as possible, because the time is too long, there will be bacteria decomposition, tube destruction, cell dissolution and other issues, affecting the accuracy of the test results. Inspection process The doctor collects the patient's urine and passes the separation test of the urine by the laboratory to determine whether the amount of various components of the urine exceeds the standard. The doctor carefully handles the test to avoid mistakes. Not suitable for the crowd Inappropriate people: Generally, there is no suitable for the crowd. Adverse reactions and risks No obvious complications and harms.
