I just finished my antibiotics yesterday for my uti. I have no symptoms. This morning I did an Azo test. It showed positive for Leu and neg for Nit?

Infection cleared: Most likely since you are now asymptomatic and the urine dip was negative for nitrites. Leukocytes are part of your body's defense system and may still be present as they finish their course of getting rid of the infection. Nitrites are a by-product of bacteria that cause the UTI. Since it is negative, likely the infection has cleared. If you develop symptoms again, see your PCP for a re-check ...Read more

Lab data: Without even knowing what the results of the tests to which you were referring are it should be noted that lab data without clinical correlation has often very little meaning. If the culture was negative and you have no symptoms it sounds as if you may be ok, but the people caring for you are in the best position to determine this. Good luck. ...Read more

I just took a UTI home test and the results came out leu positive and nit negative. What does this mean? I had a UTI early last month and my doctor gave me some antibiotics. I took all of them until they were gone.

The: The leu stands for leukocytes which are white blood cells that are usually present when there is an infection. The nit stands for nitrites, which are found when certain bacteria is present in the urine. Honestly you cannot determine if you have a UTI this way, but it is suggestive. Therefore you should go back to your doctor for a urine culture and sensitivity testing so the appropriate treatment can be initiated.
Best of luck. ...Read more

I had a UTI 3 weeks ago. Took antibiotics for 1 week. Now I am having pain again in pelvic area. I took a home UTI test kit and leukocytes positive?

You need antibiotics: You either have another UTI or the UTI that you took antibiotics never completely resolved. It is important to have a test called a "Urine Culture & Sensitivity" done whenever UTI is diagnosed in order to identify which bacteria is causing the UTI and which antibiotic will kill that bacteria. You need evaluation. It is possible that STD could be causing pelvic pain and leukocytes in a home UTI ...Read more

Symptoms start yesterday. UTI test strip positive today and lower back hurts. Getting antibiotics tomorrow but am I too late meaning kidney infection?

Symptoms start yesterday. UTI test strip positive today and lower back hurts. Getting antibiotics tomorrow but am I too late meaning kidney infection?

Probably not: Studies show pyelonephritis (kidney infection) tends to present with fever, chills, nausea, and costovertebral tenderness to palpation, in addition to urinary tract symptoms. Cystitis, or a bladder infection tends to present with urinary frequency, urgency, and dysuria (pain or burning) only. Risk factors for kidney infection exist also however more importantly you should start abx asap. Good luck ...Read more

Frequent UTI. After amox treatment 1000-9000 cfu/ml of gram positive cocci isolated. Md did not prescribe any antibiotic afterwards. Should redo test?

Ask your doctor...: First, one has to make sure that the urine was collected properly without contamination, and second, do you have UTI-related urnary symptoms? If yes, have you felt better in voiding in 1-3 days after taking Amox? And in general, a colony count of < 100, 000 cfu/ml is considered not clinically significant. More? Ask Dr or contact www.

Should I remain on antibiotics following 3 day Cipro (ciprofloxacin) treatment completion for UTI if a home test indicates positive leukocytes but negative nitrate?

Should I remain on antibiotics following 3 day Cipro (ciprofloxacin) treatment completion for UTI if a home test indicates positive leukocytes but negative nitrate?

3 day minimum: An uncomplicated UTI (no fever, abdominal pain, back pain) needs at least 3 days of Cipro (ciprofloxacin) to complete the antibiotic course.

When patients are given a longer course of medication, the UTI is likely not uncomplicated, so the entire course of the antibiotic you received should be completed. ...Read more

Hpylori: To confirm eradication you need a breath test for hpylori. If you also have anemia you may need an endoscopy and there is usually a biopsy of the stomach for hpylori. Eradication of hpylori takes 2 weeks of triple therapy including 2 antibiotics plus a PPI. Once positive the blood test is always positive. ...Read more

Hi I was tested positive for a UTI and started the antibiotics but they don't seem to be helping and sores are appearing. Why?

See doctor ASAP: It would be helpful to know more about your symptoms, especially the sores; and what UTI test was positive. New genital sores plus painful urination and maybe other UTI symptoms suggests genital herpes. Other STDs also can cause UTI-like symptoms. Maybe UTI plus severe yeast, or allergic reaction to the antibiotic. Return to your doctor ASAP. If herpes, it's important to diagnose and treat early. ...Read more

Urine recheck: You should follow up with your doctor for a urine recheck and culture. Your urine infection may be not sensitive to your current antibiotic and you so you may need a different one. A culture and sensitivity check of your urine will check this. Also if your urine comes back clear it may be your discomfort is not still due to the uti but some other infection or problem. ...Read more

Pediatric UTI: This sounds like a job for a pediatric urologist. There are many possibilities, and you have not provided sufficient info for a diagnosis to be made. A 4 yr old needs to be fully evaluated, not only for possible causes, including anatomic defects, but also for the possibility of abuse. See a good pediatrician and get a recommendation. ...Read more

Needs an antibiotic: All UTIs should be treated with antibiotics. There are no safe non-antibiotic or self treatments: the risk of a dangerous complication of UTI is far higher than an antibiotic problem. Probably this UTI should be treated with a different antibiotic than the previous one. Ask your doctor about having a culture test and, if positive, testing to see for sure which antibiotic will work best. ...Read more

Positive culture for UTI 3 weeks ago. 3 antibiotics later still having symptoms. Did another culture last week & it was negative. Inflammation maybe?

Possible: Nonbacterial causes of UTI-like symptoms and inflammation of the urinary tract can include fungal infection, adverse drug reaction, interstitial cystitis, heavy metal (eg lithium), and uric acid and hypercalcemic irritation. More remote possibilities include granulomatous diseases (eg, sarcoid or tuberculosis), polycystic kidney disease or genitourinary malignancy. ...Read more

Can being on antibiotics whilst doing a urine test affect the results? Done an sample whilst on antibiotics for a uti, still having symptoms

Should be helpful: If your symptoms are due to UTI and didn't improve on antibiotic, repeat testing is still likely to be useful by identifying bacteria resistant to the drug. Also discuss alternate diagnoses w/ your doctor, especially STDs (gonorrhea, chlamydia, trichomonas) which can cause similar symptoms as UTI; also yeast or other vaginal infections. Many UTI antibiotics aren't effective for these. ...Read more

Even though a urine test was negative, still feel as if it's a uti & test was wrong maybe. There anyway to be prescribed antibiotics anyway?

Yes and No: Sometimes one repeats a urinalysis test and does a urine culture even if the urinalysis looks normal (usually, a culture would not be done in such a case). Depending on the doctor-patient relationship and on the past history of the patient, UTI symptoms may or may not be treated with antibiotics without first testing the urine. (so, sometimes, urine is tested only if not resolving on antibiotics). ...Read more

I had signs of a UTI but my doctor said that my test was neg. For it but gave me antibiotics anyway. Everything cleared up but now I'm feel ill?

Likely unrelated: Sometimes cystitis is missed on a urinalysis, you really need a culture. Treating empirically (without urinalysis) can sometimes improve symptons and the culture returns unremarkable. Being "i'll" is kind of vague but not likely related to the urinary tract and most short courses of antibiotics will not mess up the bacteria in your colon; you could try probiotics if it's colon but should pass. ...Read more

I had UTI b4 a week I took antibiotic now imy test shows 1-3 % pus cells, no RBC count. Is this normal. But very very little pain in back point.?

What is the question: The fact that you are feeling better and no longer have pyuria (pus in urine) is good. If, however, you have had pyelonephritis (kidney infection), one week of antibiotic therapy may not be sufficient. In addition, UTI in a man generally requires a full urologic assessment to discern whether some anatomic defect was responsible for the onset of infection. Please see your doctor again. ...Read more

Daughter in law in Africa has had UTI and 3 courses of antibiotics. UTI now cleared but signs of leucolytes still there. She had more tests today.?

Persistent UTI: She may not have a simple UTI, or the bacteria are resistant to the antibiotic. Sometimes taking a bath is a potential source in rhe pediatric age group. Make sure they do a ursine culture with antibiotic sensitivities if available. She may need to see a urologist if it continues to recur or persists. Hope this helps! ...Read more
