A Complete Blood Count (CBC) test is a valuable diagnostic tool that can help detect various types of infections by analyzing different components of blood, particularly white blood cells (WBCs). Here's how it works: Types of Infections Detected by CBC Bacterial Infections : An elevated WBC count, especially an increase in neutrophils, often indicates a bacterial infection. Neutrophils are the body's primary defense against bacteria, and their levels rise significantly during such infections. Viral Infections : Higher levels of lymphocytes in the CBC can suggest a viral infection. Lymphocytes are crucial in the immune response to viruses, and their count may increase when the body is fighting off viral pathogens. Parasitic Infections : Eosinophils, another type of white blood cell, may increase during parasitic infections or allergic reactions. A high eosinophil count can indicate the presence of parasites. Chronic Infections : Monocytes can rise in response to chronic infect...
