Study Notes

White Blood Cell Count

  • Normal range: 4,500-11,000 cells/mcL

Leukocytosis

  • Defined as an elevated white blood cell count above 11,000 cells/mcL
  • Can be caused by infection, inflammation, or allergic reactions

Causes of Leukocytosis

  • Infection
  • Inflammation
  • Allergic reactions

Treatment for Leukocytosis

  • In cases of infection, antimicrobial therapy is recommended

Leucopenia

  • Defined as a decreased white blood cell count below 4,500 cells/mcL
  • Can be caused by certain medications, such as chemotherapy drugs
  • Clinical manifestation: increased risk of infection

Medications and Leukocyte Count

  • Chemotherapy drugs can cause leucopenia
  • Not all antibiotics can cause leucopenia (e.g., penicillin)

Myeloproliferative Disease

  • A possible manifestation is leukocytosis
  • Characterized by an overproduction of blood cells
