Leukocytes are part of the body’s immune system. They help the body fight infection and other diseases. They are also known as White blood cells. Leukocytes are found throughout the body, including the blood and lymphatic system. Produced in the bone marrow, they defend your body against infections and disease. But, when there are too many white blood cells, it usually means you have an infection or inflammation in your body. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders.
Types of Blood Cells
- Erythrocytes (Red blood cells)
- Leucocytes (White blood cells)
- Thrombocytes (Blood platelets)
Types of White Blood Cells
There are five different types of white blood cells, which are classified mainly based on the presence and absence of granules.
Granulocytes: They are the type of white blood cells, with the presence of granules in their cytoplasm. The granulated cells include:
Agranulocytes: These are the types of white blood cells, with the absence of granules in their cytoplasm. The a-granulated cells include:
This article concludes the introduction to white blood cells, their types, and their functions.
Leukocytes in Urine
Leukocytes may also be found in a urinalysis or a urine test. High levels of WBCs in your urine also suggest that you have an infection. In this case, your body is trying to fight off an infection somewhere in your urinary tract. Usually, that means the bladder or the urethra, which is the tube that carries urine from the bladder. Leukocytes in the urine could also suggest a kidney infection.
Leukocytes in urine don’t necessarily cause symptoms on their own. If you do have leukocytes in your urine, your symptoms will vary depending on the condition that is causing the leukocytes to build up in your urine.
The symptoms of a UTI include:
- a frequent urge to urinate
- a burning sensation when urinating
- cloudy or pink-tinted urine
- strong-smelling urine
- pelvic pain, especially in women
Obstructions in the urinary tract can cause a range of symptoms depending on the location and type of obstruction. In most cases, the main symptom is pain on one or both sides of the abdomen. Kidney stones may cause similar symptoms as a UTI but may also include nausea, vomiting, and intense pain.
