What color phlebotomy tube is used for vitamin d?

Not Medical Advice: Preferred tube type for Vitamin D testing is a Gold top/Tiger top tube SST (serum separator tube) or Mint Green lithium heparin tube (plasma separator tubes).

To prevent contamination of tubes with additives from other tubes, it is important to draw the tubes in a SPECIFIC order called "the order of the draw".

For example, if the additive in the purple stopper tube contaminates the green stopper tube this would cause falsely decreased calcium and increased potassium.

The sequence of collection of evacuated tubes in a multi-draw should be in this order:

1 - Sterile/Blood cultures (yellow top or bottles)
2 - Royal Blue - red label for trace metal analysis
3 - Light Blue coagulation tube
4 - Red - Non-Additive
5 - Red Gel separator tube (speckled or “tiger” top)
6 - Green (heparin)
7 - Green/Gray mottled Plasma Separator Tube (PST) with heparin
8 - Lavender/purple top and/or pink (EDTA)
9 - Gray top (Oxalate/fluoride tube)

For example, there was a decrease in the percentage of people taking a daily multivitamin, the researchers found. Read more at Live Science‎.
