Final answer:
Excessive white blood cells in urine is termed pyuria, which often indicates a urinary tract infection or other infections affecting the urinary system.
Step-by-step explanation:
The term for excessive white blood cells in urine is pyuria. This condition can indicate the presence of an infection, as white blood cells are part of the body's immune response to fight off pathogens. Common causes of pyuria may include urinary tract infections (UTI), pyelonephritis, or a more systemic issue such as an infection in another part of the body.
The presence of white blood cells in urine, or pyuria, often suggests a urinary tract infection where there is a pus accumulation of dead pathogens, neutrophils, and other cells involved in the immune response. In addition to UTIs, pyuria can also be indicative of kidney infections or other underlying medical conditions. In cases of significant or persistent pyuria, further diagnostic investigation is often required to determine the exact cause and appropriate treatment.
