Maximum Capacity
The printing has changed on all ARUP standard transport tubes. This change was implemented to help clients view the new maximum specimen capacity allowed for submission. The new tubes have graduated markings up to 4 mL, which is now the maximum specimen capacity. The additional air space at the top of the tube is critical to allow for expansion and prevent leakage. For this reason, liquid should never exceed 4.0 mL. If specimen requirements indicate more than 4.0 mL, the specimen should be submitted in multiple tubes.
Label Position
Follow the printed instructions on the tube. The top edge of the label should line up next to the graduated markings and be at least ¼ inch from the bottom of the tube.
