    In a urinalysis, this is a chemical that’s tested for. When leukoctyes, or white blood cells, are present in the urine, they produce this chemical called leukocyte esterase. Sometimes it can be detected even if no white cells are present as they can disintegrate and still leave behind the chemical. The 1+ is just a grading system from 0 (for none found), to 1+, which means a little, 2+, meaning a moderate amount, 3+ meaning quite a lot and 4+, translating to copious amounts. If there is leukocyte esterase present in your urine, chances are you have a urinary tract infection and should be treated for it with antibiotics before it travels to the kidneys, which could result in a very serious issue.

    It’s one of the components of urine analysis basically done to find out if the person has urinary tract infection

    Normally urine doesn’t contain white blood cells (leucocytes ) so we test urine for leucocytes when patient presents with symptoms of UTI

    We do look for blood, leucocytes and nitrate estrase to rule out infection

    So if it’s + 1 on leucocytes estrase it signifies infection and if it’s + 1 nitrate estrase its by gram negative bacteria ( one class of bacteria most commonly responsible for UTI)

    You have a small increase (1+) in leucocytes in your urine. If coupled with some protein and nitrites, you definitely have a UTI. White cells alone may be significant, or not, depending on your collection techniques.

    What does “leukocyte esterase ua moderate” mean?

    UA = urinalysis (analysis of urine)

    Leukocyte esterase (LE) = a type of enzyme contained in most leukocytes (white blood cells), tested for on a urine dipstick (first part of a urinalysis)

    The presence of white blood cells in the urine indicates inflammation of some kind. Most commonly, it indicates a urinary tract infection.

    However, there are other causes of LE being present in the urine not due to infection:

    • Such as in interstitial cystitis (inflammation).
    • Also, classically, if someone has taken phenazopyridine (brandnames Pyridium or Azo —the stuff that turns your urine orange), this test will be a false positive: that is, the test will say LE is present in the urine, but actually, this test result is caused by the drug itself. There are some other drugs that cause give a similar false positive result.

    Moderate amount is exactly what it sounds like: there’s a moderate amount of the leukocyte esterase in the urine on a dipstick.

    The urine is typically further analyzed under the microscope when a positive result such as the ‘moderate LE’ is found: visually, the presence of white blood cells is confirmed (or not). If white blood cells are found, the urine is then also typically sent for a urine culture to see if any specific bacteria are found growing in the urine.

    • They are being attracted to the bladder for other reasons (Cancer, Parasites, rough spot in the bladder wall without it being cancer.)
    • You might have a bacteria that is not utilizing “Nitrates” for energy like Enterococci, .

    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

    It may indicate a urinary tract infection. If you came to see me because of symptoms such as painful or frequent urination I would give you a prescription for an antibiotic.

    If you have no symptoms and the result was an incidental finding I wouldn’t treat it immediately and send it for culture and see if the results are truly significant.

    Esterase and Nitrite Positive urines usually mean you have a bacterial bladder infection.

    If the nitrate is negative, you may still have a bladder infection but not with E. COLI (80% of UTI’s are E. Coli). You may have an enterococcus that does not produce nitrites out of nitrates.

    Or you may have a fistula or other damage to your bladder and the white cells are guarding the bladder while healing goes on.

    If you have some white blood cells in your urine , from an at home test , it may mean nothing at all. At home tests can be highly accurate , but you need a doctor to interpret those tests.

    Every time I had a urinary tract infection, I had miserable symptoms , with burning on urination and a cramping sensation, which drove me crazy enough to get it taken care of. ( right away), by seeing a doctor. ( sometimes in urgent care, and not something that you need to go to the emergency room for.)

    I hope that answers your question .

    Your physician should be telling you, but it’s possible you have a urinary tract infection. Leukocytes are white blood cells, infection fighters.
