Nitrates are a form of nitrogen, consumed in food additives and derived from protein metabolism. The presence of nitrates in the urine is generally considered normal. However, certain bacteria that are frequently the cause of urinary tract infection produce an enzyme that changes urinary nitrates to nitrites. Therefore, the presence of nitrites in the urine is an indirect indication of urinary tract infection. It's possible to have an infection without nitrites in the urine. The only bacteria that change nitrates to nitrites are Escherichia Coli (E. Coli), Klebsiella and Proteus. Other organisms that can cause urinary tract infection which do not cause nitrates to be converted to nitrites include Pseudomonas and enterococci.
