My urine test is positive for leukocytes and negative for nitrates, is that even possible fot uti?

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. ...Read more

Why do I still have nitrates and leukocytes on my urine dipstick when the urine culture is negative?

Why do I still have nitrates and leukocytes on my urine dipstick when the urine culture is negative?

Many reasons: There are many possible reasons why a urine culture is negative but the nitrates and leukocytes are positive. 1. If your taking antibiotics then that would prevent growth of the urine culture. 2. The leukocytes and nitrates do not represent an actual bacterial infection but other viral, chemical, or environmental reasons for a positive result 3. Dipstick test or urine culture tests are false. ...Read more

Uriine-urythocytes high, ketones 20, leukocyte esters large, leukocytes 40, nitrates positive. In blood-leukocytes high, urea nitrogen low. Am I dying?

You have a uti: When a urinalysis shows large Leukocytes and nitrites positive you have a urinary tract infection and need antibiotics pending the culture report. On your blood test, you said leukocytes high which indicates infection. If you have fever and chills and back pain, could be kidney infection and may need treatment at Emergency Room now.

2 days too early!: See someone at the Sexually Transmitted Disease (STD) Clinic.

My daughter just took an at home UTI strip test and it came back positive for leukocytes but negative for nitrates. Does this mean she has an infectio?

My daughter just took an at home UTI strip test and it came back positive for leukocytes but negative for nitrates. Does this mean she has an infectio?

No: It just means it detected the breakdown products of leucocytes in the sample. You don't mention the age, which is relevant, but most home testing is done wrong. If a woman/girl does a squat pee to collect a sample it is both pee and a vaginal washout. That sample is relatively worthless. Leukocytes can also appear in the urine in any febrile child without infection. ...Read more

UTI: These home kits are meant to indicate probability that symptoms are due to infection. The absence of nitrites in the urine can mean either that the organism causing infection doesn't convert nitrate to nitrite or that the inflammation indicated by symptoms and by leukocytes is not bacterial. You should see a doctor and determine whether you should be treated. Frankly it sounds like UTI to me. ...Read more

Did urine dip at work and it is positive for nitrates and protein 3+ everything else is normal. What does this mean?

Urine dipstick: Nitrite: many bacteria produce enzyme nitrate reductase which confers the ability to convert urinary nitrate to nitrite. Positive test means possible UTI. Next step is urine culture. Protein:most sensitive to albumin in urine but positive protein (trace, 1+, 2+ 3+) may not reliable if urine sample is dilute. Dipstick may not detect albuminuria of 30 to 300 mg/day.
