Cystitis: Leukocytes are our body's defense mechanism of fighting bacteria or virus. There is a reaction occurring in the bladder for some reason (and sometimes without symptoms). If your UA shows high specific gravity (>1.025), then you may need to increase fluids in your diet. Then, periodically recheck with UA test strips. If persistent leukocytes, you may need to undergo a cystoscopy. ...Read more

Nitrite (Definition)

Comprised of nitrogen & 2 oxygen molecules. Sodium nitrite is used in meat industry to prevent bacterial growth & to maintain the meat's red color (≥ 22mg/kg body weight is toxic); cooking at high heat allows nitrites to combine with Amino Acids to form nitros-amines (carcinogens). It can be converted by many pathways to nitric oxide, a potent vaso-dilator. Amyl nitrite can be ...Read more

I took an at home uti test. Twice I was negative both times for Leukocyte and bright pink positive for nitrite.... Does this mean I have a uti??

Yes you most likely: Nitrites are highly sensitive and specific for UTI's. It is unusual that you don't have any or negative leukocytes (WBC's) though. I suggest that you go and visit your physician or local urgent care for a more accurate test to confirm the diagnosis of a UTI and to possibly get a urine culture and sensitivity done. Symptoms of a UTI include frequency, urgency and painful urination. Good Luck! ...Read more

I have often UTI, I just finished 5 d of Bactrim (sulfamethoxazole and trimethoprim), the UA shown nitrite positive, blood mod, protein 30+ and leukocyte was small. What 's to do next?

I have often UTI, I just finished 5 d of Bactrim (sulfamethoxazole and trimethoprim), the UA shown nitrite positive, blood mod, protein 30+ and leukocyte was small. What 's to do next?

Recurrent UTI...: If urinalysis was after Bactrim, (sulfamethoxazole and trimethoprim) you have resistant bacteria, need different antibiotic. Several possible causes of recurrent UTI, including persistent uncured infection; altered bladder function; and kidney or bladder stone. Sex sometimes triggers UTI. Usually recurrences can be prevented once the cause is known. Discuss with your doctor, or ask for referral to infectious diseases specialist. ...Read more

When you do a home UTI test and the results are positive for leukocytes and negative for nitrite what does that mean?

It's a maybe: White blood cells (leukocytes) can be present without nitrites with an infection, or maybe there are white blood cells present for another reason. This is a time when you should see a doctor so they can look at the urine in a microscope and possibly culture the urine to see if there really is an infection. Good luck. ...Read more

Do I have a uti? I took an at home uti test because I've been having strong foul smelling urine. It was positive for leukocytes, negative for nitrites. Could it be something else?

Do I have a uti? I took an at home uti test because I've been having strong foul smelling urine. It was positive for leukocytes, negative for nitrites. Could it be something else?

Yes: vaginal infections can have the exact same symptoms and signs and would require a different treatment. I don't think you can self test for them unless you have a "yeasty" odor and a whitish discharge, in which case you could self treat for candida. Certainly drink plenty of fluids and keep very clean down there. ...Read more

Having lower back pain. Was on Macrobid for 7days, pain started on last day. At Home UTI test positive for leukocytes but negative for nitrites. Help!

Not uti: This low back discomfort doesn't seem to be caused by a uti but is more likely due to musculoskeletal problems. If bending, etc aggravates it, it points to spinal origin. If you can take them, NSAIDS like ibuprofen may help. Your physician can evaluate you if symptoms persist. ...Read more

I have lower back pain and have been urinating more frequently and feels like I'm still urinating even when I've stopped, no burning or itching however. Uti test strip said positive for leukocytes but negative for nitrites. Is this a UTI or something else

Cystitis: The presence of leukocytes indicates cystitis or inflammation of the bladder. This is usually caused by a UTI which can be present despite negative nitrites. Low back pain, urinary urgency & frequency, painful urination may occur. Caffeine, alcohol, spicy foods, acidic foods (citrus fruits, tomatoes) may worsen the symptoms. Less likely causes would include interstitial cystitis or tuberculosis. ...Read more

What is the question: These are lab tests, the results of which cannot be interpreted outside the context of your clinical condition. You can have leukocytes in your urine without having a bacterial infection with an organism that converts nitrates to nitrites. ...Read more

Do positive leukocytes and negative nitrites indicate a uti?

Maybe: Leukocytes (white blood cells) are found in urine when there is any source of irritation (uti, stones, tumors...). Nitrites in urine are generally due to bacteria that make nitrites, but not all bacteria do so. The only way to be sure you have a UTI (and know how best to treat it) is to have the urine cultured, which means it is grown in a lab for 48-72hrs, then tested with several antibiotics. ...Read more

I took a UTI home strip test twice, both of which came out positive for leukocytes and negetive for nitrites. Does that mean I have a uti?

Possible: Not all UTIs give positive nitrite.Leukocytes could be present if urine not very cleanly collected in female (by wiping very well with antiseptic pad &labia separated).Only sure proof of infection is culture. If you did a dipstick test at home, I presume you are having symptoms. Best to see doctor & probably you will be given antibiotic probably after giving urine specimen. ...Read more

I took the at home AZO UTI test and my nitrite was negative, but the leukocytes was postie. Does this mean I have a UTI? I have pressure and burning.

Possible UTI: You may have a UTI. Nitrites may show up on the test with certain bacterial infections of the urinary tract, but not others. I recommend seeking help from a health professional for further work up. Pressure and burning can be associated with a UTI. Hope that helps! ...Read more

I have pain after peeing. And blood in my pee. I took a uti test says my leukocytes are 500+++ and nitrite is negative. What would another option be?

UTI likely: Urinary nitrite test can be negative, in spite of UTI because some bacteria such as Enterococci, Staphylococcus & Streptococcus do not test nitrite positive. Symptoms could also be due to bladder stone. Cancer, in case UR worried, is unlikely. ...Read more

Doubt UTI. PID?: Could be UTI, but unlikely with negative nitrite test and without urinary symptoms like burning on urination, urgency, etc. Sounds more like a pelvic infection, like pelvic inflammatory disease, especially if you are sexually active and at risk for STD. Or other low abdominal problem like appendicitis, diverticulitis, endometriosis, and others. Don't mess around; get professionally evaluated ASAP. ...Read more

Urge to urinate for a few weeks now, but no other UTI symptoms. AZO test strips test positive for WBC & nitrites. Is it more likely a UTI or an STD?

UTI is more likely: Gonorrhea or chlamydia can mimic some UTI symptoms, but usually this would be burning on urination; urgency alone is more likely bladder inflammation due to UTI, especially for "a few weeks" and with positive nitrite and WBC. See a doctor soon: you need a formal urinalysis, probably a urine culture, STD testing since it's on your mind, and probably an antibiotic prescription. ...Read more

Culture?: A urine culture should be performed if it hasn't. This can identify a bacterial infection if that is the cause of the leukocytes in the urine. It is possible to have a UTI and have negative nitrites. Leukocytes in the urine can also be caused by inflammation anywhere in urinary tract up to kidneys. ...Read more

I took a uti test. Urine shows leukocytes but no nitrites. Can bv cause that to happen? I have burning in vaginal opening as well

Yes: Assuming the specimen was obtained by peeing in a cup, and not with a catheter, it is very common for Leukocytes (white blood or "pus" cells) to be washed into the cup from vaginal secretions. This can happen with or without a vaginal infection. Nitrites result from bacterial metabolism of normal nitrates in the urine, and indicate possibility of urinary infection. ...Read more

I have constant lower back pain. 5 yrs.+. Positive leukocytes and positive nitrite s but no symptoms of uti. I also had bladder sling in 2002?

Unlikely o be UTI: Constant low back pain is more likely o be due to problems wih your lumbar spine. Utis are no likely o cause pain like that. X-rays of the spine may help define the problem. If that is the cause, physical therapy may be very helpful. If spine films are normal, your doctor will need to look for other problems causing pain in ha area. ...Read more

Possible UTI: Majority of UTIs are nitrite positive, however UTIs from so called "gram negative" bacteria such as enterococcus, staphylococcus, streptococcus are usually nitrite negative at urinalysis. These bacteria can be seen on microscopy & grown on bacterial culture. My advice is to get your urine cultured & have your primary care health provider prescribe some antibiotics. Good luck. ...Read more

Dr. Jie Xu Dr. Xu
1 doctor agreed:

Culture: Your doctor can send a urine culture which can tell you which bacteria is responsible and which antibiotics it's susceptible to. He or she can even start treating you empirically first with something common, like Bactrim (sulfamethoxazole and trimethoprim) ds until the culture results come back. If the bacteria is resistant, the antibiotic can be changed. Good luck! ...Read more

Test Reliability: While every test can have falsely negative results, there can well be infection that may never show nitrites. Staph and enterococcus, common UTI pathogens, do not show up positive. The test is positive when available nitrates are converted to nitrites, which the test detects. Gram negative bacteria, such as e. Coli, klebsiella, proteus and enterobacter, are common UTI bugs that do convert it. ...Read more
