If your doctor tests your urine and finds too many leukocytes, it could be a sign of infection. Leukocytes are white blood cells that help your body fight germs. When you have more of these than usual in your urine, it’s often a sign of a problem somewhere in your urinary tract.
What does it mean when you test positive for leukocytes and positive for nitrite?
If Leukocytes test is negative or trace but Nitrite test is positive: results suggest UTI. If Leukocytes test is positive and Nitrite test is positive: results suggest UTI.
Which is more indicative of UTI leukocytes or nitrites?
Therefore, the clinical impression that leukocyte esterase is the more sensitive test (more likely to be the sole indicator of UTI) and that the presence of nitrite is highly specific (i.e., highly predictive of UTI) appears to still hold.
Does positive nitrite mean UTI?
A positive result on the nitrite test is highly specific for UTI, typically because of urease-splitting organisms, such as Proteus species and, occasionally, E coli; however, it is very insensitive as a screening tool, as only 25% of patients with UTI have a positive nitrite test result.
Can you have a UTI with negative nitrites?
So, you can have a negative nitrite test and still have a UTI. This is why your doctor considers the result of many tests, not just one test, when diagnosing a UTI.
Do nitrates in urine mean UTI?
Normal urine contains chemicals called nitrates. If bacteria enter the urinary tract, nitrates can turn into different, similarly named chemicals called nitrites. Nitrites in urine may be a sign of a urinary tract infection (UTI). UTIs are one of the most common types of infections, especially in women.
What does it mean when your urine test positive for nitrates?
The presence of nitrites in urine most commonly means there’s a bacterial infection in your urinary tract. This is usually called a urinary tract infection (UTI).

Is positive leukocyte in urine test sign of uti?
A high number of leukocytes in the urine may indicate the presence of a urinary tract infection. A urinary tract infection (UTI) is a common cause of leukocytes in the urine. A UTI can affect any part of the urinary system, including the bladder, urethra, and kidneys.
What is the diagnostic test for UTI?
Tests and procedures used to diagnose urinary tract infections include: Analyzing a urine sample. Your doctor may ask for a urine sample for lab analysis to look for white blood cells, red blood cells or bacteria.
How many leukocytes for UTI?
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).
Will a kidney infection show up on an uti test?
Kidney infections can also happen following kidney surgery or due to an infection that spreads from another part of your body besides the urinary tract. Your doctor will diagnose a UTI by analyzing a sample of your urine. They can test the urine sample for the presence of things like bacteria, blood, or pus.
