Quick Answer: What Does It Mean When Your Urine Tests Positive For Nitrite?

How do I read my urine test results?

A dipstick test checks for:Acidity (pH).

The pH level indicates the amount of acid in urine.

Concentration.

A measure of concentration, or specific gravity, shows how concentrated particles are in your urine.

Protein.

Low levels of protein in urine are normal.

Sugar.

Ketones.

Bilirubin.

Evidence of infection.

Blood..

What antibiotic is used for nitrates in urine?

In our institution, we generally use cephalexin as an empirical antibiotic for the treatment of most uncomplicated UTIs diagnosed in the ED. In our study, the resistance rate was higher in the nitrite positive group for TMP/SMX and ampicillin with or without sulbactam.

How do you remove nitrates from your body?

Eat a diet high in antioxidants. Vitamin C and certain other vitamins can reduce the conversion of nitrates and nitrites to nitrosamines.

Do Stds cause nitrites in urine?

We found that in the setting of positive STI cases, positive nitrite on the urine dipstick is not a good indication of UTI. Our results showed that in STI-positive cases, nitrite-positive urines were actually 18% more likely to be associated with negative urine cultures.

Can chlamydia cause nitrites in urine?

Only 7 of 23 (30%) women with prior chlamydia were tested, and 3 of these 7 (42%) tested positive. Of women with dysuria as their only symptom, 67% had a negative urinary nitrite; however, only 7% received chlamydia testing. Of 12 women with a positive chlamydia test, 83% had a negative urinary nitrite.

What should not be found in urine?

The following are not normally found in urine:Hemoglobin.Nitrites.Red blood cells.White blood cells.

What lab values indicate urinary tract infection?

Common laboratory tests for UTIs include: Urinalysis—most UTIs are diagnosed by performing a urinalysis, which looks for evidence of infection, such as bacteria and white blood cells in a sample of urine. A positive leukocyte esterase test or the presence of nitrite in the urine supports the diagnosis of UTI.

What does it mean if you have leukocytes and nitrite in your urine?

The presence of nitrites in urine most commonly means there’s a bacterial infection in your urinary tract. This is usually called a urinary tract infection (UTI). A UTI can happen anywhere in your urinary tract, including your bladder, ureters, kidneys, and urethra.

Can leukocytes in urine be a sign of STD?

Lower UTIs and many STIs have overlapping symptomatology, including the traditional UTI symptoms of dysuria, frequency, and urgency. In addition, abnormal urinalysis (UA) findings of positive leukocyte esterase and pyuria are common in both UTIs and STIs (3–6).

What bacteria cause nitrites in urine?

coli bacteria are most commonly associated with nitrites in the urine. Having leukocytes in the urine without nitrites can also lead to a false-positive result that points to a bacterial infection when there is none.

What does a positive nitrite test indicate?

A test that is positive for nitrites in the urine indicates the presence of an organism that reduces nitrate. However, not all urinary pathogens are nitrate reducers. A positive test is highly specific for bacterial infection, but a negative test does not exclude infection, giving this test low sensitivity.

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.

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 range of nitrite in urine?

Normally no nitrites are detected in the urine. Urinary nitrates are converted to nitrites by bacteria in the urine. A positive nitrite result signifies that bacteria capable of this conversion (eg, Escherichia coli, Klebsiella, Proteus, Enterobacter, Citrobacter, Pseudomonas) are present in the urinary tract.

Why is HGB in urine?

Hemoglobin is an oxygen-transporting protein found inside red blood cells (RBCs). Its presence in the urine indicates blood in the urine (known as hematuria). A small number of RBCs are normally present in urine and usually result in a “negative” chemical test.
