Royal Blue tubes correspond to which draw?

Explanation:
Understanding the order of draw is key. The sequence is arranged to prevent cross-contamination of additives from one tube into the next. Royal blue tubes are used for trace-element and toxicology testing, so they’re placed later in the collection sequence to minimize any carryover from the tubes drawn earlier. This is why the royal blue tube is drawn as the seventh tube. There are two variants of royal blue tubes (with EDTA or no additive), but regardless of variant, the standard practice keeps them toward the end of the sequence to preserve sample integrity.
