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
• 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
• 92% water
• Contains over 100 dissolved or suspended substances: gases, vitamins, nutrients, proteins, etc.
