A.

Urine is a generally thought of as a sterile body fluid, therefore, evidence of white blood cells or bacteria in the urine is considered abnormal and may suggest a urinary tract infection such as, bladder infection (cystitis), infection of kidney (pyelonephritis). White blood cells may be detected in the urine through a microscopic examination (pyuria or leukocytes in the blood). They can be seen under high power field and the number of cells are recorded (quantitative).

White cells from the vagina or the opening of the urethra (in males, too) can contaminate a urine sample. Such contamination aside, the presence of abnormal numbers of white blood cells in the urine is significant.
