DLC, or Differential Leukocyte Count, is a blood test that provides information about the different types of white blood cells (leukocytes) present in a person’s bloodstream. White blood cells are a crucial part of the immune system and help the body fight infections and diseases. A DLC count quantifies the percentages of various white blood cell types, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils. By analyzing these percentages, healthcare professionals can identify abnormalities in the immune system and diagnose specific medical conditions like infections, allergies, and autoimmune disorders. DLC counts are a valuable tool in assessing overall health and aiding in the accurate diagnosis and treatment of various diseases and infections.
