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.
