Do leukocytes in urine always mean infection?
An increased number of WBCs seen in the urine under a microscope and/or positive test for leukocyte esterase may indicate an infection or inflammation somewhere in the urinary tract.
If also seen with bacteria (see below), they indicate a likely urinary tract infection..
What does it mean to have a trace of leukocytes in your urine?
Leukocyte esterase is a screening test used to detect a substance that suggests there are white blood cells in the urine. This may mean you have a urinary tract infection. If this test is positive, the urine should be examined under a microscope for white blood cells and other signs that point to an infection.
Is it bad to have leukocytes in your urine?
If your doctor tests your urine and finds too many leukocytes, it could be a sign of infection. Leukocytes are white blood cells that help your body fight germs. When you have more of these than usual in your urine, it’s often a sign of a problem somewhere in your urinary tract.
What are normal urine dipstick results?
Normal urinary proteins values are less than 150 mg/d and are undetectable using urinary dipstick. The urinary dipstick only detects the presence of albumin and no other proteins. When urinary protein values exceed 300-500 mg/d, the dipstick test result becomes positive.
Can a positive UTI test be an STD?
UTIs share symptoms similar to STDs and are misdiagnosed more often than you may think. According to the American Society for Microbiology, 64 percent of the patients with a sexually transmitted infection (STI) were actually diagnosed as having a UTI instead.
What does it mean when you have leukocytes in urine but no nitrite?
Leukocytes in the urine without nitrite If the test for leukocyte esterase is positive but finds no nitrite, an infection may still be present. The test is particular to certain bacterial enzymes, which means it can pick up specific bacterial infections with more certainty.
What can cause a false positive UTI test?
False positives may present if the urine specimen appears red due to any cause; for example, recent ingestion of common UTI pain relief medication containing phenazopyradine dye or contamination with menstrual fluid.
How accurate is azo UTI test?
AZO Test Strips have the same test pads as the tests used by most doctors. Our Urinary Tract Infection (UTI) Test Strips when compared to another commercial test showed 94.4% accuracy for the Leukocyte test and 98.4% for the Nitrite Test.
Will chlamydia show up in a urine culture?
Urine cultures can detect some sexually transmitted diseases. However, a urine culture is not the test of choice for sexually transmitted diseases in adults. Some STDs such as chlamydia may be tested using a urine sample, but the testing method used detects chlamydia genetic material in the urine and is not a culture.
Why do I have leukocytes in my urine but no infection?
Sterile pyuria It is possible to have white blood cells in the urine without a bacterial infection. Sterile pyuria refers to the persistent presence of white blood cells in the urine when no bacteria are found to be present by laboratory examination.
What is the normal amount of leukocytes in urine?
Diagnosis. If you’re healthy, you can still have elevated leukocytes in your bloodstream and urine. A normal range in the bloodstream is between 4,500-11,000 WBCs per microliter. A normal range in the urine is lower than in the blood, and may be from 0-5 WBCs per high power field (wbc/hpf).
What does it mean when you test positive for leukocytes and negative for nitrite?
If Leukocytes test is negative and Nitrite test is negative: no sign of UTI (if symptoms continue, test again or consult healthcare provider). If Leukocytes test is negative or trace but Nitrite test is positive: results suggest UTI. If Leukocytes test is positive and Nitrite test is positive: results suggest UTI.
Does chlamydia cause leukocytes in urine?
This looks for white blood cells (WBCs), which are virtually diagnostic of chlamydial infection or gonorrhea in the absence of urinary tract infection (UTI) symptoms. If the leukocyte esterase test result is positive, proceed with the usual diagnostic tests.
Can AZO cause false positive UTI test?
In addition, false-positive results for nitrite will occur if the dipstick is exposed to air or phenazopyridine, a common prescription and OTC product (e.g., Pyridium, AZO) used as a urinary analgesic.
What causes false positive leukocytes in urine?
 Hematuria can cause a false positive result for urine WBCs. Leukocytes and WBCs may be present in urine due to other conditions such as appendicitis, diverticulitis, sexually transmitted infection, and renal injury. False negatives can occur in neutropenic/leukopenic patients.
What can mimic a urinary tract infection?
These include chlamydia, gonorrhea, and trichomoniasis. Simple lab tests are available to distinguish a UTI from an STD. Interstitial cystitis also has many of the same symptoms as a urinary tract infection. It can happen in both men and women and can start after a UTI.
How accurate are home UTI test strips?
Home test kits are not 100% accurate. If you still have symptoms of a UTI even though the test results show that you don’t have an infection (negative result), tell your doctor.
