The positive nitrite result indicates that bacteria capable of converting nitrate into nitrite have been identified in the urine, indicating a urinary tract infection, which should be treated with antibiotics if there are associated symptoms, such as Ciprofloxacin.
Although the urine test is able to identify the presence of bacteria in the urine both by the presence of nitrite and by observation under the microscope, it is recommended to perform a more specific urine test, a uroculture, as it is able to identify the presence of bacteria in the urine. even if the nitrite is negative, in addition to indicating which species and how it behaves in relation to various antibiotics, tell your doctor what is the best form of treatment. Understand what urine culture is and what it’s for.
- The test to identify the presence of nitrite in the urine is SAA.
- Also called a type 1 urine test or abnormal sediment elements.
- Which is performed from the first urine test in the morning.
- The sample should be taken in a specific container provided by the laboratory and the genital area should be cleaned.
- The first urine stream should be discarded and the next one taken.

Some bacteria have the ability to convert nitrate normally present in urine, into nitrite, which is indicated in the reaction band used to analyze this and other aspects of urine. However, even if the result is negative for nitrite, this does not mean that there are no bacteria in the urine. In fact, some bacteria do not have this ability, and are only identified when urine is examined under a microscope or by a urine culture, which is a more specific test.
Diagnosis of urinary tract infection using SAA usually occurs when, in addition to the positive nitrite, several leukocytes, erythrocytes and bacteria are observed during observation under the microscope.
Positive nitrite treatment in the urine test should be guided by a urologist or family doctor and is usually performed with the use of antibiotics, such as amoxicillin or ciprofloxacin, for 3, 7, 10 or 14 days, depending on the drug used, dose and severity of infection.
However, when there are only changes in urine testing without symptoms, treatment may not be necessary, as the body can fight the infection. In these cases, your doctor will schedule a new urine test to evaluate the progression of the infection.
If nitrite is positive during pregnancy, a woman should consult the gynecologist or obstetrician to start treatment with the most appropriate antibiotic for pregnancy, such as cefalxine or ampicillin, as there is an increased risk of developing kidney infection.
