White blood cells, leukocytes, protect the body from external danger, fight pathogenic microflora, destroy and remove toxins from the body. The appearance in the body of inflammation leads to an increase in leukocytes in the blood. However, these cells can be observed in the urine. What is the rate of leukocytes in the urine of a child, as evidenced by the increase or decrease in the average figures, what to look for and when to start panic, every parent should know.
Why do leukocytes rise in the urine?
The current laboratories at polyclinics and hospitals are equipped with modern devices that consider automatic analyzes. Laboratory technicians no longer have to work by counting cells and inclusions in a drop of blood or urine. And parents can rely on the accuracy of the analysis, because automatic calculation eliminates the human factor. But you should not blindly trust even the most modern technology, so if the results of the tests are questionable, then the test should be passed again and the results obtained should be compared, or go to another laboratory. Modern medical centers provide similar services for a fee everywhere.
Normal in the field of view the number of leukocytes should not exceed 10 - this is the upper limit. In boys and girls, the norm values differ:
- In boys, the figure is 5 leukocytes;
- In girls, 6 leukocytes.
In different sources, there are other numbers, to judge how much the norm is exceeded, only a pediatrician can.
One of the reasons why a large number of leukocytes is observed in the urine of a child is non-compliance with the standards of personal intimate hygiene. If the container for analysis is unsterile, the baby is poorly cleaned, then the result will be greatly distorted. As a rule, when obtaining similar results, the doctor prescribes the delivery of urine again to eliminate the possibility of error.
In order for the analysis to be reliable, the child is washed with warm water and wiped with a clean towel or diaper. It is important to know that in order to make a general analysis of the sweets, collect the middle proportion. To collect urine from babies, urinals are specially designed for this purpose, which are fixed in the groin with adhesive tape. They do not cause any discomfort to the child. Collecting urine, twisting the diaper or diaper, pouring it out of the pot is not recommended so as not to distort the test results. For storage and testing use sterile containers that can be purchased at each pharmacy. Parents who use empty bottles for medicines or products in the old-fashioned way should take care of the sanitary standards: wash the dishes with soap or soda, pour boiling water (including the lid) and dry them.
When re-receiving non-comforting numbers, you can make an assumption that your child has an infection of the urogenital system:
- Inflammatory processes in the kidneys (pyelonephritis - an infectious disease, thunderelonephritis - damage to the renal glomeruli);
- Inflammation of the bladder (cystitis);
- Inflammation of the urethra (urethritis);
And also about parasitic diseases (enterobioza), allergic reactions, disorders of metabolic processes. If the doctor has a suspicion that there are parasites in the child’s body (for example, pinworms), he prescribes an additional analysis.
Parents should be aware that the increase in leukocytes in the urine in children can be caused by physical exertion (sports, dancing), as well as a large amount of protein foods.
Normal levels of leukocytes in the urine in children
The table shows the norms of leukocytes in the urine of a child. The rate indicator varies with age.
Age of child
Norm of leukocytes, * 109/ l
Up to a year
6 - 17.0
3 - 4
5.5 - 15.5
5.0 - 14.5
6 - 10
4.5 - 13.5
10 - 16
As can be seen from the table, in the urine analysis, the rate of leukocytes in children can vary greatly. Only a doctor can judge whether the situation is causing anxiety and whether every specific situation requires taking any particular measures.
Low white blood cell count: is there any cause for concern?
Since, in the analysis, the upper limit of the content of leukocytes in the urine is specified, their low content or lack of them should not alarm the parents. A "pure" analysis indicates the absence of inflammatory processes in the urinary tract.
Parents of a child under one year should take a urine test every 3 months (unless otherwise indicated). The older the child becomes, the less often the parents appear in the clinic with containers filled with urine. The pediatrician prescribes the analysis if the baby has a high temperature and keeps, as well as other complaints related to the work of the urinary system arise: pain in the back, stomach, pain, difficulty and urination, blood in the urine. In this case, the child is subject to observation and requires additional examinations.
Parents often seek to look at the results of the analysis before the doctor sees them. Mom, knowing what the rate of white blood cells in the urine of a child, panic if the numbers differ from the standard. But in this situation it is important to understand that only a specialist can fully assess the totality of factors influencing the results of the analysis, draw conclusions and prescribe, if necessary, treatment. If there is no confidence in the pediatrician, the doctor should be changed, but in no case should self-medicate.
