What does it mean when you have leukocytes in your urine?
Leukocyte esterase is an enzyme present in most white blood cells (WBCs). A few white blood cells are normally present in urine and usually give a negative chemical test result. The most common cause for WBCs in urine (leukocyturia) is a bacterial urinary tract infection (UTI), such as a bladder or kidney infection.
Platelets are made in your bone marrow along with your white and red blood cells. Your bone marrow is the spongy center inside your bones. Another name for platelets is thrombocytes. Healthcare providers usually call a clot a thrombus.
- Primary thrombocytosis, also known as essential thrombocythemia (or ET), is a disease in which abnormal cells in the bone marrow cause an increase in platelets. The cause is unknown. Secondary thrombocytosis is caused by another condition the patient may be suffering from, such as: Anemia due to iron deficiency.
- Another name for red blood cell is erythrocyte. 'Erythro' means red; 'cyte' means cell. RBC is an acronym for red blood cells. RBCs carry oxygen and carbon dioxide around our body.
- A platelet (also called a thrombocyte) is a cell in the blood. Platelets help your blood to clot after an injury, like when you fall and scrape your knee. These clots help you stop bleeding.
Leukocytes are the first line of defense of the immune system. Leukocytes are derived from bone marrow stem cells and have three main categories: Lymphocytes, Phagocytes, and Auxiliary Cells. Neutrophils, basophils, and eosinophils are called granulocytes because they have granules in their cytoplasm.
- Lymphocyte, type of white blood cell (leukocyte) that is of fundamental importance in the immune system because lymphocytes are the cells that determine the specificity of the immune response to infectious microorganisms and other foreign substances.
- A high white blood cell count is an increase in disease-fighting cells in your blood. In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count. A high white blood cell count is also called leukocytosis.
- Neutrophils. They kill and digest bacteria and fungi. They are the most numerous type of white blood cell and your first line of defense when infection strikes. Basophils.
A megakaryocyte (mega- + karyo- + -cyte, "large-nucleus cell") is a large bone marrow cell with a lobated nucleus responsible for the production of blood thrombocytes (platelets), which are necessary for normal blood clotting.
- Platelet Production. Platelets are produced in the bone marrow, the same as the red cells and most of the white blood cells. Platelets are produced from very large bone marrow cells called megakaryocytes.
- A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC).
- Megakaryocytic hyperplasia along with dysplastic changes is a characteristic feature of malignant or clonal disorders and seen in several chronic myeloproliferative neoplasms like chronic myeloid leukemia, polycythemia vera, or essential thrombocytosis, myelodysplastic syndromes, early phase of myelofibrosis, and acute
