White blood cells (WBCs) are vital to the immune system, defending against infections and diseases. Elevated or reduced WBC counts can signal health issues like infections, leukemia, or autoimmune disorders. For bacterial infections, antibiotics like ceftriaxone injection, supplied by reliable ceftriaxone injection suppliers, are often prescribed to support WBCs in fighting pathogens. Low WBC counts may indicate bone marrow issues or viral infections, requiring diagnostic tests. Monitoring WBC levels helps doctors assess disease severity and treatment efficacy. Maintaining a healthy immune system through diet and lifestyle supports WBC function, reducing disease risk and aiding recovery.
