One of the most important indicators as a result of the analysis of daily urine in children is the protein content, the excess of which can indicate the development of dangerous ailments. In this article, we will tell you what the concentration of this substance should be in children's urine, and in what cases additional examinations should be carried out.
What is the permissible norm of protein in the urine of a child?
Normally, the concentration of protein in the urine of a child at any age is extremely small. According to the generally accepted rule, it should not exceed 0.14 g / day. If the index reaches 0.15 g / day, the baby can already be diagnosed with mild proteinuria.
At the same time, exceeding the level of protein in the urine of an infant is considered a variant of the norm if the baby is not yet 2 weeks old. This is due to the peculiarities of the hemodynamics of the newborn, associated with an increase in the permeability of the glomerular epithelium and the renal tubules.
In addition, collection of urine for analysis requires compliance with certain rules, so minor deviations may be due to lack of hygiene in girls or physiological phimosis in boys. That is why in all cases when receiving the results of the analysis with increased values of protein concentration, it is recommended to repeat the study. When confirming the violation of the baby must be sent to additional examinations in order to exclude serious diseases.
Typically, the deviation of protein in the urine in the child from the norm is associated with such causes as diabetes, severe stress and fatigue, dehydration, burns and trauma, as well as various infectious diseases and inflammatory processes in the kidneys. The pronounced increase in relative to normal values almost always indicates such serious ailments as amyloidosis, as well as nephrotic syndrome in acute glomerulonephritis.
