Blood Collection Tubes and Order of Blood Draw

Vacuum tubes with color coded stoppers indicating the additive contained are used for blood collections. In the Alphabetical Test Directory, the color coding is indicated as well as the volume of blood required for each test.

When collecting blood specimens, it is important to allow the tube to fill completely and to follow the correct “order of draw”. Click here for vacutainer tubes, and click here for microcollection tubes. Never pour blood from one tube into another tube.

For blood collection tube requirements for tests ordered on the CLS Acute Care requisition, see Tube Type Quick Reference - Acute Care.
