Therefore, the clinical impression that leukocyte esterase is the more sensitive test (more likely to be the sole indicator of UTI) and that the presence of nitrite is highly specific (i.e., highly predictive of UTI) appears to still hold.

Does positive nitrite mean UTI?

A positive result on the nitrite test is highly specific for UTI, typically because of urease-splitting organisms, such as Proteus species and, occasionally, E coli; however, it is very insensitive as a screening tool, as only 25% of patients with UTI have a positive nitrite test result.

Can you have a UTI with negative nitrites?

So, you can have a negative nitrite test and still have a UTI. This is why your doctor considers the result of many tests, not just one test, when diagnosing a UTI.

How many leukocytes for UTI?
