White Blood Cell Count (WBCC)

“Normal” count is 5000-10000 cells per mm3 of blood

What does it mean if your WBCC is higher than 10000? (leukocytosis)

What does it mean if your WBCC is lower than 5000? (leukopenia)

Differential White Blood Cell Count (DIFF)
  • Shows percentages of each type of WBC.
  • Useful in diagnoses:
    • Neutrophils increase in bacterial infections.
    • Eosinophils increase in some parasitic infections and allergic reactions.
    • Lymphocytes decrease sharply in AIDS.
blood platelets
Blood Platelets

AKA, thrombocytes

Not complete cells – fragments of cytoplasm that are released by pieces breaking off large cells in red bone marrow

These, and the megakaryocyte “parent cells”, develop in response to the hormone thrombopoietin.

No nucleus, less than ½ the size of RBC’s

blood plasma
Blood Plasma

92% water

Contains over 100 dissolved or suspended substances: gases, vitamins, nutrients, proteins, etc.
