Seventy urine samples were positive for leukocytes and nitrite chemistry, and 30 were negative for both.

Leukocytes or WBCs are a part of your immune system and include granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells). Together, these WBCs help the body fight infections and other diseases. In general, measuring the leukocyte count is a part of a complete blood cell count (CBC) test ( 3 ). My home UTI kit said that my urine was negative for nitrates, but positive for Leukocytes. From what I have read, Leukocytes only mean the body is fighting off something (inflammation is present) but that the nitrates would mean postiive for UTI. ...

That's normal for us because our bladders bleed. Leukocytes are just white blood cells, which is going to end up in there if we're bleeding. Negative nitrites means that you don't have an ecoli infection. Ecoli makes up the vast majority of UTIs, but its still possible to have an infection from a bacteria that isn't going to produce nitrites. The objectives of this study were to identify all sources of nitrite in urine and the range of concentrations associated with these sources and to determine if nitrite adulteration can be supported based upon a quantitative result. ... clinical specimens nitrite positive by test strip (< 15 micrograms/mL); specimens culture <b>positive</b> for nitrate. Negative leukocytes and positive nitrites means that only nitrites were detected in your urine. Testing positive for nitrites indicates that you have bacteria in your urine. Although some bacteria is present in the urine of healthy people, an increased number of bacteria will produce more nitrites, which likely indicates that you have a UTI..

The leukocyte esterase test in our study was found to be non sensitive indicator for UTI. Positive predictive value of this test was found to be low (60.2%) but a negative leukocyte esterase test (89%) excluded UTI indicating good NPV. The reasons for low sensitivity are reported in literature. If your leukocyte is positive, but nitrite is negative, there is a possibility that you have infection. The best thing would be to repeat the test next morning. Make sure to clean the area first,if the leukocyte is still positive, even if nitrite is negative, see your physician!.

What is leukocytes in the urine without nitrite? If the test for leukocyte esterase is positive but the nitrite one is negative, this can still mean there is an infection. The reason for this is a limitation of the nitrite test. It is very specific, which means it can pick up a bacterial infection with certainty. 1.

If the dipstick test is negative for nitrites and leukocyte esterase, UTI is less likely, especially if symptoms are mild.

With an indwelling catheter — make a working diagnosis based on clinical judgement.

Leukocytes in the urine without nitrite If the test for leukocyte esterase is positive but finds no nitrite, an infection may still be present. The test is particular to certain bacterial enzymes, which means it can pick up specific bacterial infections with more certainty.

None of the 200 UTIs with positive nitrite yielded enterococcus (upper confidence interval, 1.4%).

How many leukocytes in urine is normal? Diagnosis. If you're healthy, you can still have elevated leukocytes in your bloodstream and urine. A normal range in the bloodstream is between 4,500-11,000 WBCs per microliter. A normal range in the urine is lower than in the blood, and may be from 0-5 WBCs per high power field (wbc/hpf). The most common cause for white blood cells in urine (leukocyturia) is a bacterial urinary tract infection (UTI), such as a bladder or kidney infection. In addition to white blood cells, bacteria and red blood cells may also be seen in the microscopic examination. If bacteria are present, the chemical test for nitrite may also be positive. Nitrite.

Leukocyte esterase is an enzyme that is released by white blood cells (WBCs) and therefore correlates with pyuria. Some bacteria (such as E. coli) convert urinary nitrates that are routinely present in the urine into nitrite. Therefore, a positive nitrite test on the urine dipstick is suggestive of the presence of these organisms.
