Yes: Leukocytes mean your body is making an inflammatory reaction. A positive nitrite test indicates a gram negative bacteria is present. You could have a bladder infection with a bacteria which does not convert nitrates to nitrites. An example is enterococci, which can cause an infection, cause white cells, yet not change the nitrites portion of the dipstick. Microscopic exam and culture are important.

Urethritis: A urine test with positive leukocytes suggests local inflammation, commonly in the bladder in women or the urethra ( tube carrying the urine from the bladder to the outside)in men. Inflammation of the urethra ( urethritis) is commonly caused by chlamydia infection, but may have non infectious causes also. Your doctor may prescribe antibiotic.
