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

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 ...Read more

Urine tests showing increased wbc/leukocytes without nitrites indicate?

See below: If the diet is lacking in nitrates, lack of nitrite in urine is meaningless. There may be infection with organisms that do not make nitrite, or the infection may be in the urethra. All lab results need to be interpreted in the clinical context and the doctor who ordered the test is in the best position to do that. ...Read more

+40 leukocytes in urine but neg for nitrites.? Been having UTI symptoms but only mild.

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

Urine reagent strips promo to check urine. All normal (including nitrites) except leukocytes. Color between trace (15) and small (70). Uti? No symptoms.

Unlikely: Urine dip is not the most specific test for UTI but when combined with symptoms of burning sensation, cramps, urgency, frequency, hesistancy it enhances the diagnosis. Otherwise without any symptoms, nothing too conclusive I would say. ...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?

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

Ua showed I was negative for leukocytes. Negative for white blood cells but positive for nitrites and many crystals in urine. Is this normal?

Clinical symptoms?: It is possible to have a UTI that only shows positivity for nitrites and be negative for wbcs. Studies have shown that when nitrites are positive, a UTI has a strong chance of being present (= good specificity for the test). Many crystals can be caused by kidney stones or food metabolism issues. ...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

Nitrites, trace blood and leukocytes in urine, smells fishy/ammonia a few weeks after starting dexedrine. Pain and burning in bladder, NEG. UTI. Cause?

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

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?

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

GU infection: Please seek help for a suspected urinary tract infection as soon as possible. You may need to give urine for retesting and culture, depending on history and exam. Hopefully, there is no kidney infection. Hopefully, there is no sexually-transmitted infection or very rarely, urinary tract tuberculosis. ...Read more

Hi I have just dipsticked my urine it show ph of 9 and leukocyte is this anything to worry about.

Stone?: Some bacteria like Proteus associated with Struvite stones produce an enzyme called Urease which increases urine pH and can produce white cells or leukocytes in the urine. This is one possibility. The second is that you are taking a medication that alkalinizes urine. Please review your med list. ...Read more

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 ...Read more

What is meaning of leu neg nitrite pod. And leuk pos nitrite neg urine dips?

Uti: When both leucoyte and nitrites are positive then it is strongly indicative of uti. If only leucocyte is positive and nitrite negative, it can still be uti, but with organisms who doesn't convert to nitrite, low urine ph or early phase of uti. Vice versa also indicates UTI and if alone nitrite is pos it is still a strong predictor of uti. In all circumstances clinical signs and symptoms are imp. ...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
