What is additive phlebotomy?
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant).
Which should be the first in order of draw for blood collection?
first tube to be drawn is a coagulation tube, a discard tube must be drawn first. The discard tube must be a non-additive, no clot activator, or a coagulation tube. NO clot activator or additive tubes should be drawn before coagulation studies.
How do you remember additives in phlebotomy tubes?
The order of draw is an order of tubes phlebotomist should follow to prevent testing complications and cross-contamination of additives. The order of draw is Yellow, Light Blue, Red, Light Green, Dark Green, Lavender, and Gray. Way to remember this is by the saying Your brother Robert gives lovely gifts.

- Lavender (EDTA)
- Pink – Blood Bank (EDTA)
- Gray (Oxalate/Fluoride)
What is the correct order of draw tubes only?
The correct order of draw follows: Blood culture tube or bottle. Sodium citrate tube (eg, blue closure) Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)
What does order of draw mean?
To avoid cross-contamination, blood must be drawn and collected in tubes in a specific order. This is known as the Order of Draw.
What’s the Order of the phlebotomy blood draw?

What’s the correct order to draw plastic tubes?
The order is universal for glass and plastic tubes, and irrespective of whether samples are drawn with a tube holder or syringe. The recommended order is as follows: Sodium citrate tubes (e.g., blue-stopper)
Why do you need a gray stopper for phlebotomy?
Tubes with gray-colored stopper contain sodium fluoride or potassium oxalate additives, which acts as an Antiglycolytic agent that helps preserve glucose for up to five days. This requires full draw, as the opposite may cause hemolysis.
How does a phlebotomist invert a blood sample?
A phlebotomist inverts each blood sample by rotating the tube vertically by 180 degrees. The infographic below displays what constitutes as one full inversion. These inversions are necessary to mix the blood specimen with each tube’s additive to ensure that there is no cross-contamination between tubes.
