Positive leukocyte esterase in urine. Does that mean UTI?

Positive leukocyte esterase in urine. Does that mean UTI?

Generally: Yes it does. BUT... while it certainly means some wbc's in urine, this may or may not be worth treating. Certainly if there are symptoms or a lot of wbc or a change in kidney function. But if it is entirely asymptomatic. then. Not so sure.

Urine (Definition)

Urine is the product of the kidneys, which is produced to eliminate the waste products of metabolism, manage body fluid balance, &maintain acid-base balance. The blood is first filtered by the kidneys, and the composition of the resulting fluid is then altered depending on the body's needs. It is composed of mostly water, and breakdown products from blood cells impart ...Read more

Does an urinalysis report of: leukocyte esterase 1+, urine WBC 6-10 and squamous epithelial cells 0-5 mean an infection?

Does an urinalysis report of: leukocyte esterase 1+, urine WBC 6-10 and squamous epithelial cells 0-5 mean an infection?

Not necessarily: Voided (vs. Catheterized) urine specimens in women are potentially subject to contamination. Urine culture is the definitive method of determining the presence of infection. Another important point is that in older women in the absence of symptoms, this kind of urine abnormality alone or even a positive culture should not be treated with antibiotics (asymptomatic bacteriuria).

GFR - 117.35, Albumin-4.6, leukocyte esterase-positive, urine WBC-25. Cud this indicate kidney disease? No symptoms of UTI. ANY suggestions?

WBC on UA: The serum albumin and GFR seem fine, but you have some WBC and leukocyte esterase in the urine. Could be a subtle infection. Could be an inflammatory condition of the bladder or kidney. Should be investigated.

What does having a trace of leukocyte esterase urine mean?

Usually normal: Leukocyte esterase released by lysed neutrophils and macrophages is a surrogate marker of the presence of white blood cells (WBCs). Leukocyte esterase suggests that there are white blood cells in the urine. Trace means few WBC produced small amount of leucocyte esterase

Why would someone need a leukocyte esterase urine dipstick test?

Urinary infection: Leukocyte esterase is a surrogate marker for the presence of white blood cells in the urine and usually indicates urinary infection.

What do these test results mean? CO2 20 LO, ALT 36 HI, MPV 12.1 HI, Ketone, Urine 3+, 80 mg/dL, *Leukocyte Esterase MODERATE *, WBC, Urine 5-10 HI

Discuss results: The Dr who ordered the test needs to provide feedback to you in a way that clarifies the impact on your Dx and Tx options. It should make sense to you or it is not a finished piece of work. Get a consult and perhaps bring someone along to help you understand and remember the details.

Urobilinogen Qualitative Urine 2.0mg/dL, Leukocytes Esterase Urine 75 WBC/uL, WBC Urine 11-25/HPF, RBC Urine 2-5/HPF. What does all this mean?

Urobilinogen Qualitative Urine 2.0mg/dL, Leukocytes Esterase Urine 75 WBC/uL, WBC Urine 11-25/HPF, RBC Urine 2-5/HPF. What does all this mean?

UTI: It looks like a urinary tract infection, to me. And, by the looks of the WBCs, it may be moving towards a kidney infection. You should see your doctor to be evaluated. Get well soon!

All urine results, neg, but LEUKOCYTE ESTERASE shows MODERATE. What does this mean? Last time it was SMALL/Clear. This time MODERATE/SLIGHTLY-CLOUDY.

Urinalysis: Cloudy urine and urine containing white blood cells (leukocytes) don't necessarily signify a urinary tract infection. The white cells may be contaminants from a vaginal infection or discharge. A clean catch urine culture would rule in or out a urinary tract infection. If you have a vaginal discharge, see your gynecologist and he/she can order any appropriate urinary tests if no vaginal infection

Should I be concerned if my leukocyte esterase result was 500 and blood number in urine was 25? If so what could be problem?

Should I be concerned if my leukocyte esterase result was 500 and blood number in urine was 25? If so what could be problem?

Infection: Elevated leukocyte esterase and blood in the urine can indicate infection. Hopefully your doctor sent the urine for a culture and sensitivity to find out the cause of the infection.

I had a blood test and urine test. Everything was normal, but my urine test showed leukocyte esterase said small (1+) (negative)a. I took another one he said 99% it will be fine. I'm freaking out.

Not to worry: The urine dip test is only a screening test. In women, it is not unusual to find a small quantity of leukocyte esterase in the urine which can be from vaginal contamination. A urine culture is the definitive test for urinary tract infection. In the worst case scenario if you culture is positive, a short course of antibiotic is usually all that is needed to cure it.

How abnormal is 5-10 for WBC in a urine test? I am curious about a small abnormality on my physical: the results of the urine chem/microscopy say “trace” of leukocyte esterase (reference range: negative) and a “flag” says ab. Following that the WBC is “ab

A: A few white blood cells in the urine of a female patient is very common, especially if the urine sample was not collected in particular manner. If a physician is interested in getting urine from a woman's bladder that has not been contaminated by passing through the vagina, which normally contains bacteria and white blood cells, the sample should be collected by asking the woman to use a antiseptic towelette to wipe the vagina while spreading the inner labia, then to urinate into the toilet for a second, stop urinating, then urinate into the specimen cup. If you didn't collect the urine in this manner, then it's more than likely that the white blood cells are from the vagina, not the bladder as are the bacteria and the leuk esterase. If it is noted that there were squamous epithelial cells in the urine, then it's even more likely, because those cells are found only in the vagina, not the bladder. Back pain is a common symptom, and occasionally it is the sole symptom of a urinary tract infection, but not usually. Most of the time people with utis will have pain on urination or frequency of urination, fevers, or pain on the sides of their back. If you have any of these (fever, urinary pain or frequency, or pain on the sides of your back) or if the middle back pain persists for more than a week, you should see a doctor. But the biggest thing here is, the physician who ordered the urine test should be available and eager to answer your question.

Hi I had a urine test and had positive leukocyte esterase. No other symptoms. Can it mean anything other than a UTI or could it be lab error?

Bacteria: It means you have bacteria in your urine sample. It could mean a UTI, but it also could just be a contaminant, like cells from your skin. If it was a very small amount, and the rest of your urine test was normal, than probably nothing.

How do I get a high white blood count in my urine but test negative for nitrites and leukocyte esterase?

How do I get a high white blood count in my urine but test negative for nitrites and leukocyte esterase?

UA results: Nitrites indicate bacterial abundance. If negative, then very low grade infection or no infection exists. Leuk esterase indicates leukocyte enzyme release, reflecting battling leukocytes. If neg, then no leuk attack present, or very low grade. So --- leukocytes without infection do appear in urine from interstitial nephritis, usually allergic, or from interstitial cystitis, usually of unknown

Had blood and urinalysis 7/15. Blood work was all normal but urine showed creatinine level of 409, trace protein, trace leukocyte esterase, WBC, hyali?

Had blood and urinalysis 7/15. Blood work was all normal but urine showed creatinine level of 409, trace protein, trace leukocyte esterase, WBC, hyali?

Stop worrying: I understand you have fibromuscular dysplasia of the renal arteries and hope this can be addressed. The urine creatinine, trace protein and hyaline casts are non-issues, the trace of leukocyte esterase and white cells (unless very numerous or you have symptoms of infection) are likely contamination, and if your physician is not concerned, I would not be either. Best wishes.

My urine test finding were WCB Esterase trace, Leukocytes 25 WBC 6-10, epithet non renal >10. I was dealing with a yeast infection. Is there more?

Repeat UA: If you were treated for the infection and are now cured, I would suggest repeating the Urine analysis in coming few weeks. Ensure done when you are not menstruating and provide a clean sample. If the UA is still abnormal then will need further workup.
