The norm of protein in children in urine. General urine analysis

Today we will tell you what is the norm of protein in children in urine. Methods of determining the readings in urine will also be described.

Urinalysis refers to one of the simplest methods of diagnosing any abnormalities in the human body. It is taken from children from an early age in order to identify or refute diseases.

Indication for this study

There are several points when the doctor prescribes to pass a urine test in children for laboratory testing:

protein norm in children in urine

  1. Before the planned vaccination to identify the condition of the body. The fact that the baby before the vaccination should be completely healthy.
  2. In the case of a child suffering from a disease. The doctor determines by results whether the treatment is being treated correctly or whether something needs to be changed.
  3. In prophylactic purposes, it is recommended to take urine test once a year. So it is possible at an early stage to identify this or that disease.

Norms of protein for different age categories. Decoding of urinalysis in children. Table of indicators

You should know that the child's kidneys on averagerecycle about 50 liters of urine. For comparison: the kidneys of an adult person are processed around 180. And only 2 liters a day are excreted from the body. The volume of urine that leaves the child's body depends on its age, the state of the body. Is there protein in the urine of a child in the year and older?

urinalysis in children

It is known that if the body is normal, then in urineit will not be found. Or it will be in such a small amount that it can not be distinguished by laboratory research. And what is the protein norm in children in urine? Now we'll figure it out. If the concentration of protein in the child's urine is less than 0.036 g / l, then everything is in order, this is the norm. Therefore, there is no cause for concern.

Indicators of about 1 g / l indicatemoderate increase. And if a laboratory test shows 3 g / L protein in the urine, then this indicates a high content. The rates at which the protein norm in children in the urine is exceeded is called proteinuria. Next, the pediatrician appoints to pass an analysis to identify the number of it. This is done to detect kidney disease or track the treatment process.

Methods for determining

A little higher, we told you what is the norm of protein in children in urine. But how to identify this indicator in general? What are the ways to determine?

increased protein in the urine of a child

  1. Lowry's method.
  2. Geller's trial.
  3. A sample by means of sulfosalicylic acid or pyrogallol.
  4. Express diagnostics is carried out usingspecial indicator strips. This method can be used both in a hospital and at home. The main advantage of analyzing this method is the instantaneous result. For this, the strips descend into the urine. Then in a couple of seconds you can determine whether there is protein in the urine or not. If the strip becomes color, then it is present.

By means of urine indicators, it is possible to determinepresence in the body of any deviations. Therefore, it is recommended to take urine analysis in children. This is especially true for toddlers who have kidney and urinary tract diseases.

Features of the child's body. The causes of increased protein norms

Features of the newborn organism are such thatit adapts to new living conditions. Therefore, almost ninety percent of children have an elevated protein level in the urine. After a certain period of time, the process of kidney function is normalized. Then the urine test comes back to normal.

In addition, the protein content may increase for the following reasons:

  1. Subcooling of the child's body.
  2. Any nervous overstrain, stress.
  3. Increased temperature.
  4. Allergic reactions.
  5. Lack of fluid in the body.
  6. Defeat the skin with burns.
  7. Taking medication for a long time.
  8. The reaction of the body to the sun.
  9. Fright of the child.

It should be noted that if the protein in the urine is increasedthe child is insignificant and there are small deviations from the norm, as a rule, this means that there are no pathologies in the child's body. After a certain time, this indicator comes back to normal.

protein in the urine of a child per year

As for the newborn babies,that the protein in the urine in a child is elevated, is considered a normal reaction. After three weeks, he should be back to normal. In the body there are traces of protein in the urine of a child.

Causes of pathology development

If this indicator remains the samelevel, then an additional examination of the baby is required in order to identify the cause. Perhaps the child has a disease associated with the kidney or ureter.

You should know that the diseases are not uncommon in infants. There are several reasons why these ailments may be present:

  1. Heredity.
  2. Disturbances in fetal development.
  3. Infection, which was present at the mother.
  4. Trauma caused by childbirth.
  5. Hypoxia.
  6. Infection with any infection in the hospital after childbirth.
  7. Infection in the home environment with a fungus.

As a rule, kidney disease passes without symptoms in babies at this age. Even if they have abdominal pain, parents can write it off to normal colic.

Therefore it is recommended with special attentionto concern to check of an organism of the child for presence in it of any diseases connected with kidneys. You should know that violations in the work of the kidneys and urinary tract can be inherited. Therefore, if close relatives have diagnosed diseases of this kind, it is necessary to pass a urinalysis for prophylactic purposes. It is better to repeat it after a while.

Parents need to pay attention to whether there isthe child has swelling on the legs, if there are bags under the eyes. Perhaps, there are traces of clothing on the skin of the baby. Also, with kidney disease, the skin has a pale color and the temperature rises. Another sign of the presence of a pathology associated with urination is discomfort or pain in this process.

What does elevated protein indicate?

What is the protein in the urine of a child above the norm? There are a number of diseases in which a similar pattern is observed. These include:

  1. Various kidney diseases, such as pyelonephritis, glomerulonephritis and others.
  2. Any trauma to the kidneys.
  3. Diabetes.
  4. Myeloma ailment of the body.
  5. Hemoblastosis.
  6. Insufficient amount of fluid in the body.
  7. High pressure.
  8. Epilepsy.
  9. Infection.


If the urine protein level is higher than normal, it means that its content in the blood is reduced. Outwardly it becomes apparent that there is not enough of it in the child's blood. Symptoms:

  1. Breast babies quickly get tired of sucking mother's breast.
  2. The child constantly sleeps or wants to sleep.
  3. He eats poorly.
  4. The temperature rises.
  5. The child is sick and vomits.
  6. The color of urine changes, it becomes with a red or brown tinge.

If the baby has the above symptoms, then you should make an appointment with a pediatrician. He should give directions to urine and blood tests.

traces of protein in the urine of a child

Parents, whose children are prone to kidney disease,it is recommended to constantly check the level of protein in their urine. The easiest way to identify this indicator at home is to do the test with the help of special strips. But you should know that there are diseases in which this method will be ineffective. In this case, you need to take a daily urine test to identify the pathological process in the child's body.

Parents at the first suspicion thata child in the body there is some pathology, should not be delayed with a visit to the pediatrician, since timely diagnosis of the disease significantly facilitates the healing process.

A small conclusion
