A complete blood count - CBC - includes information about all of the formed elements in the blood.

Right now, we're going to focus on the various populations of white blood cells. The rest comes later

Before we get started on the white blood cells, here's some food for thought regarding the complete report itself.

  • The CBC is the most commonly ordered test in medicine.
  • More mistakes are made here that cost time and money.
  • Report layouts vary, so you need to understand what's behind the numbers.
  • Deals mostly with "formed" or so-called "cellular elements."
    • WBCs
    • RBCs
    • Platelets
  • Can you imagine some sources of error?
  • Always ask yourself, do the results fit with the clinical situation?
