Order of Blood Draw

On October 14, 2010, in Tests, by Andrea

Despite our thoughts on the matter, there is an actual process to the order for our blood draws.  Some tubes can render several tests, and some tubes should be drawn before others.

Here is the order, according to Bakerman’s ABC’s of Interpretive Laboratory Data, Fourth Edition:

Vacuum Tubes:

  • Sterile Tubes (Blood Culture)
  • Red Top Tubes
  • Blue Top Tubes (Coagulation)
  • Gel-Separator Tubes
  • Green Top Tubes (Heparin)
  • Lavender Top Tubes (EDTA)
  • Grey Top Tubes (Oxalate/Fluoride)

Capillary Tubes:

  • EDTA Anticoagulated Blood
  • Tubes containing other anticoagulants
  • Tubes with clotted specimens

    My vampires are very careful to organize my tubes so they take as little blood as possible. I appreciate this!
