Order-of-Draw Mastery is Only a Click Away
What is the Phlebotomy Order of Draw?
The phlebotomy order of draw is a specific order blood samples must be drawn in, based on the additives in the blood collection tubes. It is based on the Clinical & Laboratory Standards Institute (CLSI) venipuncture standard.
Why Do I Need to Know It?
Every phlebotomist should know the proper order of a blood draw to prevent cross-contamination of the blood samples that could result in inaccurate test results.
