Not all people are strong in anatomy, but almost every one of us has heard such a term as leukocytes. These little colorless bodies contained in our body play a very important role in the fight against pathogenic bacteria. The concentration of leukocytes can be determined by taking a urine test. Let's take a closer look at what they say leukocytes, the rate in the urine of which varies depending on gender and age.
Permissible rate of leukocytes in the urine
Leukocytes are produced by our bone marrow and lymph nodes. At different periods of life, as well as depending on gender, the number of these cells in the body should be different. During the development of various diseases and pathologies caused by bacteria and other pathogens, colorless bodies eat pathogenic microorganisms, thereby enhancing our immunity. After the destruction of an infected microorganism, leukocytes die off and come to the surface in the form of pus.
Treating experts say that the rate of leukocytes in the urine indicates the state of human health. With the deviation of this indicator in any direction there are suspicions about the development of the disease.
During a clinical study of a comparative sample, the color of urine, its transparency, acidity, specific gravity and concentration of colorless bodies are determined. Leukocytes are also determined in the urine sediment, the rate of which, as already mentioned, is different in children and adults.
Perhaps many of the fair sex are now interested in information about what should be the rate of leukocytes in the urine. For a long time, doctors argued about the rates of the content of such cells in the female body. Through long studies, the main criteria were derived, which today are generally accepted.
Conducted a study of urine in the laboratory using microscopic equipment. The number of leukocytes is determined in the segment visible under the microscope. In a healthy woman, the content of leukocytes in such a sample should not exceed 10 units.
If the number of leukocytes varies from 10 to 50, then this is considered an insignificant deviation from the norm and women should not have any concerns about their health. When more than 50 leukocytes are found in the urine, this indicates an inflammatory process. There are cases when the number of leukocytes in the sample of urine cannot be counted. It speaks of serious disorders and pathologies developing in the body.
After the onset of pregnancy, the female body begins to actively rebuild, hormones and metabolic processes change. Often, due to the development and increase of the fetus and uterus, pressure is exerted on the bladder, kidney or ureter, as a result of which inflammation may occur.
In the first trimester of pregnancy, the number of leukocytes in the urine may slightly increase, but there is no reason for panic. But if their concentration does not subsequently change and remains elevated, this may indicate the development of the inflammatory process in the organs of the urinary system.
Normally, in a pregnant woman, the number of leukocytes in the urine sample should be from 0 to 10. In all other cases, you should contact your doctor and undergo a full-scale examination. In practice, it is often found when the fetus and uterus block access to the kidneys, so only clean urine without pathogenic leukocyte count enters the bladder. In this case, the woman is examined to identify concomitant symptoms.
Some experts believe that in a normal pregnant woman the level of leukocytes should not exceed 6 units in the visible area. However, most doctors are of the opinion that their normal concentration is 10 units.
Increasing the level of concentration of leukocytes in the urine in medical practice is called leukocytosis. Moreover, this disease is much more common in women than in men. In a healthy man, the concentration of leukocytes in the urine normally ranges from 0 to 3 units in the test sample.
If a specialized analyzer is used for the study, then the number of such bodies should not be more than 10 units in 1 μl. When a man notices that the urine is cloudy, has some kind of sediment and an unpleasant smell, this may indicate the development of the inflammatory process. In this case, you should immediately contact the attending specialist. About the presence of pathology, as a rule, says leukocytosis. As practice shows, the deviation of the level of leukocytes from the norm in the urine in men most often indicates the appearance of inflammatory processes in the urethra.
The child has
The number of leukocytes contained in the urine of young girls and boys is also different. For girls, the norm is no more than 10 units in the visible part of the comparative urine sample, but for boys this figure should not exceed 7.
The norm of leukocytes in the urine of a month-old baby is somewhat different from the content of such bodies in older children. A newborn girl in the urine should be no more than 6-8 units, and the boy - 5-7. In all other cases, doctors conduct a full-scale examination in order to identify the development of the inflammatory process.
The concentration of leukocytes in the urine in boys and girls differs due to the peculiarities of the anatomical structure of the urogenital system.
Analysis of comparative urine samples according to Nechiporenko is carried out according to a detailed special method. In this case, 1 ml of urine is examined to determine the concentration of red blood cells, cylinders and leukocytes. According to the results of this analysis, conclusions can be drawn about the presence of pathologies in the kidneys, as well as in other organs of the urinary system.
Normally, the concentration of leukocytes should not exceed 2000 units in 1 ml of urine. Only on the basis of information about the concentration of leukocytes, all types of cylinders and erythrocytes in the urine can an accurate diagnosis be made.
Why does leukocyte count increase?
As already mentioned, the increase in leukocyte concentration in a comparative urine sample is called leukocytosis. As a rule, an increase in the number of whitish bodies in the urine is due to the influence of the following factors:
- manifestation of an allergic reaction;
- connective tissue diseases;
- the presence of inflammatory foci;
- development of helminthic invasions.
In addition, an increase in the number of leukocytes in a comparative urine sample is directly related to the development of a number of diseases, especially inflammatory ones:
- injuries received;
- neoplasms of malignant or benign type;
- disorders of metabolic processes.
Only the attending specialist can determine the reason for obtaining the pathological result of urine analysis. Do not try to decipher the analyzes yourself. The doctor will conduct a full examination, and if necessary, you will be asked to take a number of other tests, undergo an MRI, ultrasound.
How to pass the analysis?
In order for the test results to be reliable, urine samples should be taken for a comparative study taking into account certain rules:
- only the first urine (morning) is suitable for analysis;
- in front of the toilet, you need to properly clean up without the use of cosmetic means;
- utensils for urine collection must be sterile;
- the first portion of urine is slightly down, and the second is collected in the container;
- women using a tampon should close the vaginal passage, and gently push the labia;
- urine must be delivered to the laboratory no later than 2 hours after sampling;
- capacity can not be shaken.
The concentration of leukocytes in the urine can determine the presence of inflammatory processes in the body. If the primary symptoms occur, consult your healthcare professional. Be healthy!
