Why Are White Blood Cell Counts Important for Health?

White blood cell (WBC) counts are important indicators of overall health because they reflect how well the body's immune system is functioning. A high WBC count may signal infections, inflammation, or immune system disorders, while a low count can suggest weakened immunity, bone marrow issues, or the effects of certain medications. Monitoring WBC levels helps doctors diagnose conditions early and track responses to treatments. For example, patients prescribed antibiotics such as cephalexin capsules distributors often undergo blood tests to ensure the medication is working effectively and not negatively impacting immune health. Balanced WBC levels are vital for fighting infections and maintaining wellness.
