What bacteria causes nitrates in urine?
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.
What does it mean to have nitrates in urine but no leukocytes?
The presence of nitrites in the urine is highly specific to certain bacterial infections. Nitrites do not occur with all types of bacteria. An absence of leukocyte esterase in the urine means that the urine is not likely to contain white blood cells, so it is not likely to be carrying infectious agents.
Are nitrates specific for UTI?
According to data in this table, the urinary nitrite test has a sensitivity of 92 to 100 percent and a specificity of 35 to 85 percent for diagnosing UTI.
Can you have nitrates in urine without infection?

What causes high nitrate levels?
Detritus, decaying plant material, dirty filters, over-feeding, and overstocking the aquarium all contribute to increased levels of nitrate. Additionally, tap water used to fill the aquarium may contain nitrate in it. In the United States, drinking water may have nitrates as high as 40 parts per million (ppm).
What causes high nitrate levels in urine?
Another cause of nitrates to appear in urine is bacteria. Some bacteria cause a urinary tract infection (UTI) that induces a chemical reaction in the body to make an enzyme that changes urinary nitrates to nitrites.
What foods contain nitrite?
Cured Meats And Bacon. Nitrates are added to cured meats and bacon products.
What causes Elevated nitrite in urine?
