Positive cells indicate the presence of leukocytes in specimens tested in body fluids such as urine, stool, and secretions, and generally indicate the possible presence of a bacterial infection, or what is commonly referred to as inflammation.
Leukocytes are a general term for a group of cells in the blood, including neutrophils, eosinophils, basophils, lymphocytes, etc. Leukocytes play an important role in the immune function of the body. Under normal circumstances, a small number of leukocytes can be found in body fluids such as urine, stool, and secretions.
It is important to note that a positive leukocyte test in human urine or secretions, as an auxiliary diagnostic technique, can only mean the presence of leukocytes in the test specimen, but it does not clarify whether there is a bacterial infection and what kind of pathogenic infection it is. Acute infections caused by various bacteria such as pneumonia and appendicitis, serious tissue injuries such as major surgery and myocardial infarction, as well as leukemia and malignant tumors can all lead to a positive leukocyte test, so a clear diagnosis can only be made by combining medical history and other relevant laboratory tests.
In summary, a positive leukocyte test indicates the presence of leukocytes in the body fluid specimen, suggesting the possible existence of infections and other pathologies, but the diagnosis needs to be made in conjunction with the medical history and other relevant laboratory tests.
