What this test is

This test measures and evaluates key components of your blood, including red blood cells, white blood cells, and platelets. The 'differential' part of the test breaks down the different types of white blood cells present.

  • White Blood Cells (WBC) — body's response to infection and inflammation
  • Hemoglobin — protein in red blood cells that carries oxygen
  • Hematocrit — proportion of red blood cells in the blood
  • Platelets — blood clotting ability
  • WBC Differential — specific types of white blood cells
