What is the Difference Between Whole Blood and Serum Blood?

Hi I’m attorney Kevin Hayslett and I’m here with forensic toxicologist, Ron Bell, and the question is, “Is there a way to collect blood in, let’s say, in a medical setting, verses that of a legal, let’s say, DUI investigation setting, to ensure accurate blood alcohol results?

Ron: There are two different types of blood samples commonly referenced in forensic cases or in legal community and that is whole blood and medical blood.

  • Whole Blood: Is blood with all of its components
  • Medical Blood: References serum. Serum is a portion of whole blood and it can be thought of as the liquid portion without the solid components, such as red blood cells and white blood cells.
