Which color comes immediately after pink in the standard order of draw?

• A. Gray
• B. Pink
• C. Lavender
• D. Dark Green

Answer: (C)

In phlebotomy, tubes are collected in a fixed sequence to prevent cross-contamination of additives and protect test accuracy. In this standard sequence, the pink tube is drawn before the lavender tube. The pink top is used for blood bank compatibility testing, and immediately after that, the lavender tube (EDTA for CBC and similar tests) is collected. This arrangement helps keep compatibility testing samples separate from CBC samples and reduces any potential additive carryover that could affect results. So, the color that comes immediately after pink is lavender.
