Urinalysis is one of the basic tests that helps us diagnose many diseases. Urine produced in the kidneys contains metabolic products that are useless for our body. They are expelled this way.
Is nitrite in urine normal?
Under physiological conditions—in a healthy body—the urinary tract is a sterile environment, meaning there are no microorganisms in the urine. Microorganisms can only appear in the terminal urinary tract, entering via the ascending urinary tract from the perineum. A normal urine test for both children and adults should not reveal nitrites. Nitrates are present, which come from food intake and protein metabolism.
What do the nitrites in the baby's urine mean?
Nitrates are converted to nitrites in the presence of gram-negative bacteria. Therefore, if a urinalysis test indicates the presence of nitrites, the cause is usually an infection, i.e., a bacterial urinary tract infection. To confirm this, additional tests should be performed, but above all, the patient's symptoms should be assessed. Urinary tract infections are quite common in children, but they should never be ignored. Their general symptoms can vary:
- fever, sometimes with vomiting
- stomach pain, pain during micturition (urination)
- tearfulness
- lack of appetite.
Expert advises
Depending on the age of the child, it may be difficult to assess such symptoms - the younger the child, the more difficult it will be for us to assess them. Performing a urine test helps to make the correct diagnosis. The presence of nitrites in the urine or an increased number of white blood cells (leukocytes) is a signal that a urinary tract infection is possible and you should contact your doctor. Usually, urine cultures are also performed to properly treat the patient.
Czy nitrite in the urine always mean the presence of bacteria?
Do nitrites found in a child's urine always indicate the presence of bacteria and a developing infection, or can they sometimes indicate something else? A false positive urine test result indicating the presence of nitrites is possible. This occurs when the urine sample was not stored properly – i.e., the urine sample was left at room temperature for too long, resulting in the growth of bacteria, which do not necessarily originate from the urinary tract . If in doubt, the urine should be collected again and delivered to the laboratory in appropriate conditions.
Is there a lack of nitrite in the urine is it no infection?
If there are no nitrites in the urine, does that mean the child doesn't have a urinary tract infection? Even if nitrites aren't detected in the urine, bacteria may be present. This occurs, for example, in cases of frequent urination – the presence of urine in the bladder for too short a time (polyuria). To diagnose a urinary tract infection, we always need to assess the patient's symptoms and evaluate other parameters from the tests performed (leukocyturia in a urinalysis, urine culture).
Urine nitrite: whether and how to treat?
The real question is whether to administer medication to a child solely based on the presence of nitrites in the urine? Certainly not. A medical consultation and additional tests, as recommended by the doctor, are necessary. Properly selected treatment guarantees rapid improvement and effective recovery.
Nitrite in urine after furagin: what to do?
What if a child treated with furagin, which is often used to treat urinary tract infections, has nitrites in a urine test? If the urine was properly collected and delivered to the laboratory under appropriate conditions, it's essential to contact a doctor if nitrites are detected in the urine after furagin administration. It may be necessary to change the therapy and use a different medication. However, this decision should always be made after analyzing the symptoms—whether they are still present, have worsened, or have resolved—and based on the evaluation of other additional tests. Changing the medication too hastily is also not recommended.
How can I prevent urinary infections in children?
In order not to worry about the presence of nitrites in urine, it is worth preventing urinary tract infections in children in the first place.
The simplest advice is proper hygiene of intimate areas – a large proportion of urinary tract infections in children are so-called ascending infections, i.e., a consequence of the presence of bacteria in the lower urinary tract. In infants, parents are responsible for this, and as children grow older, it is essential to develop appropriate hygiene habits in children.
