How many leukocytes indicate a UTI?
In females with clinical findings suggestive of UTI, urine microscopy may be indicated even if the leukocyte esterase dipstick test is negative. Pyuria is most accurately measured by counting leukocytes in unspun fresh urine using a hemocytometer chamber; more than 10 white blood cells (WBCs)/mL is abnormal.
What is a high number of leukocytes in urine?
An unusually high number of leukocytes in the urine indicates inflammation or infection along the urinary tract, often in the bladder or kidney. These will show in a urine test.
What is the normal range of UTI?

What is the uf-1000i cut off value for urinary tract infection?
Based on the results obtained in this study, when using the UF-1000i analyzer for a screening test for UTI, a cutoff value of 40 white blood cells/microL should be adopted. The cutoff value for bacteria should be 125/microL for those clinical conditions in which 10 x 10 (5) CFU/mL indicates a positivity.
What does WBC and leukocytes mean in a urine test?
This is because WBCs are part of the immune system, and they help fight off disease and infection. Leukocytes may also be found in a urinalysis, or a urine test. High levels of WBCs in your urine also suggest that you have an infection.
