Methods for Testing Leukocytes in Urine
When it comes to detecting leukocytes in urine, doctors rely on routine urine sample testing. Patients typically visit their doctor when experiencing symptoms such as pain or general discomfort. During the appointment, they will be requested to provide a urine sample, which will then undergo a dipstick test. This simple procedure involves using a plastic strip coated with specific chemicals that is inserted into the urine sample. In the presence of white blood cells, the strip will change color, indicating the presence of leukocytes and alerting the doctor to the issue at hand.
Understanding the Significance of White Blood Cells in Urine
When white blood cells are found in a urine sample, it can be a sign of a urinary tract infection. This infection can occur in various parts of the excretory system, such as the kidneys, ureters, bladder, and urethra. However, the bladder and urethra are the most common locations for these infections to occur. The primary culprit behind these infections is often the invasion of E. coli bacteria from the gastrointestinal tract. Specifically, an infection in the bladder is referred to as cystitis, while an infection in the urethra is known as urethritis.
