Understanding Whole Blood Serum and Plasma - DCN Dx

Mar 17, 2020 Citrated plasma drawn in a blue-topped tube is the sample preferred for coagulation factor testing. Complete blood count samples are drawn in a purple- or lavender-topped EDTA tube. Plasmas are also not interchangeable. EDTA plasma has an excess of a powerful chelating agent that will sequester metal ions such as calcium and magnesium.
