A CBC panel is an inventory of blood components, including white blood cells, red blood cells, and platelets. Normal platelet counts range from 130,000 to 440,000 cells/mm3, and low counts, known as thrombocytopenia, can lead to bruising and bleeding, caused by various factors including drugs and autoimmune diseases. The document outlines the significance of platelets in blood clotting and the implications of low platelet levels.

13. Complete Blood Count (CBC)- Platelets
Platelets (thrombocytes) are necessary for blood
clotting.
A normal platelet count is about 130,000-440,000
cells/mm3.
Low platelet counts (thrombocytopenia) -- which can
lead to easy bruising and excessive bleeding -- may
be caused by certain drugs, autoimmune reactions,
accelerated destruction by the spleen, or certain
immune diseases.
