Urine findings indicating a urinary tract infection typically include which combination?

In urinary tract infections, the urinary findings that best point to infection combine evidence of bacteria with signs the bladder and urinary tract are irritated and inflamed. Bacteria in the urine indicate the infectious organism is present, and a positive nitrite result comes from many common urinary pathogens that can convert nitrates in urine to nitrites. The white blood cells reflect the body's immune response to the infection, producing pyuria. Together—bacteria, nitrite, and white blood cells—create a classic pattern that strongly supports a urinary tract infection. The other options describe findings that are not typical markers of a UTI. Oval fat bodies with protein suggest nephrotic-range proteinuria and lipiduria rather than infection. Yeast with white blood cells can occur with a fungal infection, but nitrite elevation is not a usual feature. Amorphous urates are urine crystals and do not indicate an infectious process.
