Leukocytes in the analysis of urine - one of the main indicators of the study. The pathology, in which the number of leukocytes increases, is called leukocyturia. Most often this means that the body develops an inflammatory reaction. How are white blood cells indicated in the analysis of urine, and what can the deviations of their indicators from the norm indicate?.
The elevated white blood cell count in the urine indicates the presence of inflammation. Leukocytes in the urine Leukocytes are white blood cells involved in immune and inflammatory reactions. Leukocytes are formed in the lymph nodes and red bone marrow. In the analysis of urine there are different designations for these cells - LEU and WBC (white blood cells - white blood cells), according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net Increased white blood cell count, especially in repeated urinalysis, requires a detailed examination of the patient.
There are five types of leukocytes, each of which differs in its physical and functional characteristics:.
| Neutrophils - provide the basic defense of the body against bacteria, fungi and protozoa. Localized in the foci of inflammation, neutrophils surround and phagocytize with bacterial agents and tissue degradation products with the help of lysosomal enzymes;.
Lymphocytes play a central role in immune responses, are responsible for acquired immunity, promote tissue regeneration;.
Monocytes - have the highest ability for phagocytosis, absorb particles of foreign physical agents and foreign cells in the blood;.
| Eosinophils - carry out extracellular destruction of parasitic organisms, are able to phagocytize microbial cells, fight with particles-carriers of allergens in the inflammatory focus. Activating, eosinophils accumulate and release inflammatory mediators;.
| Basophils - secrete mediators of inflammation that increase vascular permeability, regulate blood clotting and vascular permeability, play an important role in allergic reactions of immediate type.
Leaving the bloodstream, leukocytes penetrate into any organs and tissues. In healthy people, white cells enter the urine through the mucous membrane of the ureters and the bladder, the parts of the renal glomeruli and the tubule system in a small amount. With the development of an inflammatory response due to the destruction of tubules and cellular infiltration, conditions are created for the excess release of leukocytes from the focus of inflammation into the urine. In this case, the presence of white blood cells is detected in the urine during laboratory tests.
Leukocytes in the general analysis of urine A general (clinical) analysis is one of the most simple and accessible methods for determining the level of leukocytes in the urine. When it is carried out, the obtained sample of the biomaterial is studied under a microscope.
With 100 or more leukocytes in the field of view, they speak of pyuria - the excretion of pus in the urine. The number of leukocytes in this state can reach 500 or more.
Many factors can affect the composition of urine and distort the results of the analysis. These include the drinking and nutrition regime, the intake of medicines, physical and emotional loads. To get the most accurate result, you need to properly prepare for the analysis.
The day before the study should exclude significant physical exertion, try to limit stress. Contraindicated bath and sauna visit.
Fatty and fried, as well as any products that can change the color of urine (carrots, beets and other brightly colored vegetables and fruits, synthetic vitamins) should be excluded from the diet 1-2 days before the analysis. Also, do not drink alcohol, coffee, sweet and sodas. Acceptance of any medication, if possible, should be suspended (this should be consulted with your doctor). If a break in the reception can not be done, you need to make a complete list of medications taken and report it to the doctor who gives directions for analysis. Women during menstruation are advised to postpone urinalysis for several days.
