Urinary leukocyte positivity of 2+ medically indicates the presence of a significant number of white blood cells in the urine test. The main causes of urinary leukocyte positivity 2+ include the following:
1. Urinary tract infections: The most common cause is bacterial infection, such as urinary tract infection, urethritis, cystitis, etc. These infections cause white blood cells to accumulate in the urine, leading to an increased number of white blood cells as a response to the inflammatory reaction in the urinary system.
2. Pelvic inflammatory disease: Infections in areas such as the uterus, fallopian tubes, and ovaries may also lead to an increased number of white blood cells in the urine, resulting in urinary leukocyte positivity of 2+.
3. Other causes: An increase in urinary white blood cells is not always caused by infection; it may also be a transient phenomenon due to strenuous exercise, sexual activity, dehydration, and other factors. If urinary leukocyte positivity occurs only once and there are no obvious symptoms, it may not be a cause for excessive concern.
4. Kidney diseases: For example, pyelonephritis, a kidney infection caused by bacterial infection, can also lead to an increased number of white blood cells in the urine, causing urinary leukocyte positivity of 2+.
