Question

Quizplus · Accepted Answer

A urine sample collected directly from the urinary bladder is collected using a sterile catheter, therefore it should be sterile. If it contains bacteria, it indicates a urinary tract infection. Leukocyte esterase is an enzyme produced by white blood cells and indicates that there are white blood cells in the urine, which can be a sign of infection. The presence of more than 100,000 pathogens/ml indicates a significant bacterial infection, while the presence of fewer than 10,000 pathogens/ml is considered insignificant. The presence of fewer than 100 pathogens/ml would be extremely low and unlikely to cause infection.
