What does positive white blood cell count mean? Inflammation of the urinary system

Many people find that their white blood cells are positive through routine urine tests, which means that there is a disease in our urinary system. In severe cases, there will be symptoms such as frequent urination, urgency, pain, fatigue, and back pain. It is necessary to have a comprehensive examination and timely antibiotic treatment.

1. The urine of a normal adult may contain a small number of white blood cells, but it is abnormal when the number exceeds a certain amount.

2. Reference range: Normal person's mixed drop of urine WBC0-3/HPF by microscopic examination

3. Centrifuged urine WBC0-5/HPF (WBC refers to white blood cells, HPF refers to high power field)

4. Clinical significance: Increased leukocytosis in urine is seen in urinary tract infection, chronic pyelonephritis, cystitis, and prostatitis. More leukocytosis can also be found when female leucorrhea is mixed with urine. In addition, due to allergic reactions caused by drugs, a large number of eosinophils (a type of white blood cells) will appear in the urine.

5. Usually, when the white blood cell test is positive, you should first check whether you have other symptoms, such as edema on your body, whether your urination is normal, etc., before you can make a diagnosis. A plus sign for white blood cells in the urine is not serious, but it should not be ignored. Further diagnosis and treatment is recommended. The treatment plan for each disease is different, so it cannot be generalized. Medication should be used after a confirmed diagnosis.

6. Generally, if the white blood cell test is positive, a re-examination is required. The urine may be contaminated. If the white blood cell test is still positive or more, a urine sediment test can be done to see how many white blood cells there are. Generally, the presence of white blood cells in the urine indicates urinary tract infection. If there are symptoms, drug treatment can be avoided for the time being. If you have symptoms such as frequent urination, urgency, and pain when urinating, you should consider using antibiotics to fight the infection.
