What does a UA/Culture report indicate if it shows more than 10 WBC?

A urine analysis (UA) that reveals more than 10 white blood cells (WBC) per high power field is indicative of a potential urinary tract infection (UTI). The presence of elevated WBCs in urine typically signifies that the body is responding to an infection or inflammation in the urinary system. White blood cells are crucial components of the immune system, and their increased levels suggest that the body is fighting off infection, which is often the case with UTIs.

In contrast, the other choices do not accurately reflect the implications of a WBC count above this threshold. Normal urine function would not show elevated WBCs; dehydration might lead to concentrated urine but would not necessarily present with increased WBCs; and kidney stones often cause irritation or obstruction but would not specifically indicate the presence of WBCs unless accompanied by an infection. Thus, the identification of more than 10 WBCs in a UA/Culture report is a significant finding that merits further investigation for a urinary tract infection.
