Suspecting a disease, doctors often send the patient for urine analysis. This type of laboratory research allows specialists to diagnose the state of the immune, cardiovascular systems, kidneys and other organs. If a large number of white blood cells in the urine is detected, it is worth being wary. Find out why.

What is white blood cells in urine?

So-called white blood cells, whose task is to suppress infections, protect the body from harmful microorganisms. The photo shows that these large blood elements are not colored, differ in structure, purpose, are the main elements of the immune system. Cells are able to pass into all organs, tissues, can move independently thanks to pseudopods.

If a person increases the number of bacteria, viruses, foreign particles, white blood cells destroy them, they die themselves and are excreted in large volumes in the urine. According to the analysis, the doctor diagnoses the inflammatory process. The presence of leukocytes in the urine is not a pathology if the norm is not exceeded (according to the table). You should sound an alarm if a certain threshold is exceeded..

How to take a urine test

This type of diagnostic study is very important, it is prescribed for suspected a variety of diseases, as well as to monitor the effectiveness of treatment.

To get reliable results, you should not go to the doctor if the temperature is elevated, menstruation is on, blood pressure is increased. Recommendations for passing the analysis:

  1. The day before the delivery of the biomaterial, you should avoid food that can affect the color of the fluid secreted by the kidneys: beets, brightly colored fruits, marinades. It is not recommended to drink coffee, dietary supplements, alcohol.
  2. It is advisable not to visit a sauna or bath, to exclude strong physical exertion.

The rate of white blood cells in urine

Many are interested in the question – how many leukocytes should be in the urine? Any doctor will explain that the amount is affected by a person’s age, gender and other important factors. For example, increased rates are observed due to treatment with certain drugs in pregnant women. White blood cells are large, larger than red blood cells. In a healthy person, the norm is considered an amount from 0 to 5 in women and from 0 to 3 in men. When the number of described cells in the analyzes exceeds 6, the volume of red blood cells is increased, a similar condition is called leukocyturia.

How to determine the norm of white blood cells? Alone – no way. If there is a suspicion of a serious illness, you need to go to the doctor and pass an analysis, following the recommendations. The study of biomaterial is carried out by specialists. For analysis, it is subjected to centrifugation in a graduated tube, the resulting precipitate is examined under a microscope or using automatic equipment.

White blood cells in the urine of a child

Doctors regularly issue directions for urine tests to infants and children in order to identify problems in time and prevent the development of inflammatory processes and pathologies. An ideal general analysis should show a white blood cell count close to zero. A single excess is permissible depending on the age of the child, the baby. For example, the norm of white blood cells in urine in male children can vary at the level of 0-7 white blood cells, in girls – from 0 to 10. The more white bodies are found, the more acute the disease develops in infants..

The level of white cells in pregnant women is initially high. The reason is the increased protective properties of the body due to antigenic load. The norm of white blood cells in urine during pregnancy is from 0 to 3 units.

The norm of white blood cells in urine in women

If the white blood cells are normal, in women the indicator is not higher than 6 units. If leukocyturia has a pronounced degree, this can be seen visually: the liquid released becomes cloudy, includes lumps, mucus, and various threads.

To get an accurate diagnosis, the doctor may prescribe a re-analysis, while the fluid is taken from the bladder.

The rate of leukocytes in urine in men

It is considered normal if a urine test for white blood cells shows up to 3 cells in the field of view. If the indicator is higher, we are talking about the excess and the presence of any pathology. The cause of a poor analysis may be inflammation of the urethra, infections of the genitourinary system, the presence of kidney stones, ureter, pathology of the connective tissue, tumor diseases, and so on..

The norm of leukocytes in urine according to Nechiporenko

If the general analysis shows an increased number of blood cells, the doctor may prescribe an analysis according to Nechiporenko to clarify the diagnosis. The method helps to identify the amount of protein, red blood cells, white blood cells, cylinders. In a healthy person, white blood cells in urine according to Nechiporenko should not exceed 2000 in 1 ml. If there are more of them, comparing all the information received, the doctor will be able to identify diseases of the kidneys, urinary tract.
