It is also possible to have leucocytes in urine and suffer symptoms of bacterial infection without proof of infection. A urinalysis will detect, in addition to the number of leukocytes, bacteria and nitrites. If the patient is immunosuppressed or has been using a urinary catheter for some time, he or she is much more likely to develop a kidney infection. Kidney infection or pyelonephritis is one of the most serious infections and is accompanied by pain, frequent urination, high fever, chills, tachycardia and vomiting. These symptoms appear suddenly, without warning and with varying intensity. Cystitis is caused by bacteria and its symptoms may include burning and/or painful urination, frequent urination, cloudy and foul-smelling urine, and sometimes weakness, tiredness and fever. It may result from cystitis or pyelonephritis. In fact, this is the most common cause, especially in women. As mentioned above, this is the first thing you think of if there are a lot of leukocytes in the urine. The first thing that is usually thought if leukocytes are found in the urine is that it is caused by a urine infection. Urine white blood cell test results should always be correlated with the patient’s health status (symptoms, history of any disease, medication intake, etc.). In most cases it is a minor health problem. Even a slight increase in their number should not alarm us. The presence of a certain, low number of leukocytes (up to 5 per high-resolution field, at a field of 400x magnification) in urine may be normal. The presence of an elevated number of leukocytes (white blood cells) is called ‘leukocyturia’. In addition to studying the results of cells and bacteria, the presence of leukocytes in urine is also analyzed.Īn elevated number of red blood cells in the urine sediment (red blood cells) is called hematuria. For this purpose, a physical, a chemical and a microscopic analysis of the urine is always performed. Urinalysis is one of the most demanded and common tests in a clinical analysis laboratory. They are part of the defense against parasites, in allergic reactions, in atopic skin and asthma. They contain histamine, an indispensable molecule for the immune system. They constitute less than 1% of leukocytes. They are also involved in allergy processes and, together with basophils, are the least abundant group of leukocytes in the blood. They are the main defense against parasites. They will also be able to show the collected debris to other cells to generate specific antibodies against viruses or bacteria. Macrophages are also capable of ‘alerting’ other cells that an attack is taking place. These will inactivate and destroy the foreign material. Once inside, they will dump highly oxidizing molecules on top of the phagocytosed product. Once there, they will evolve into macrophages, cells capable of clearing an area by phagocytizing the attacker or the dead cell. If there is an external attack or in front of own dead cells to be removed from the organism, monocytes leave the blood and travel to the affected tissue. There are 2 main types of lymphocytes: B lymphocytes (generate antibodies) and T lymphocytes (eliminate infected cells, cancer cells and control immune reactions). This is the second largest group of white blood cells in the body. When they are released at the site where an invasion is occurring, they attack the foreign structure and ‘call’ other defense cells. They are among the most numerous leukocytes and contain a wide variety of chemicals (enzymes, messenger molecules, etc.). They are one of the first cells to react to infection. The former are basophils, eosinophils and neutrophils, while the latter are monocytes and lymphocytes. They are usually classified based on the presence or absence of granules (small inclusions that look like ‘stippling’ when the cells are viewed under the microscope: granulocytes or agranulocytes. As part of the immune system, their function is to help the body fight infections and various diseases. It is found in both blood and lymphatic tissue. Therefore, today we will see why leukocytes in urine mean and what are the problems that could derive from them.Īs mentioned above, a leukocyte is a type of blood cell (hence it is often called a white blood cell) from the bone marrow. If its level is elevated, it can also degenerate into disease. The presence of leukocytes, for example, in the urine is associated with various conditions. However, their number does not always mean good news. Its main mission is to defend the organism from foreign substances or infectious agents. Also called leukocytes, white blood cells are part of the blood cells that execute the immune response. It may be its most striking color, but at no time should we disregard the latter. Red blood cells may be more popular than white blood cells.
