Final answer:
The order of draw is the sequence for filling blood collection tubes, and the acronym BDP LABS helps remember the order to prevent cross-contamination between tube additives.
Step-by-step explanation:
The term order of draw refers to the sequence in which blood collection tubes should be filled during a blood draw. This is important because it prevents cross-contamination between different types of additives in the tubes which could affect test results. One common acronym used to remember the recommended order is BDP LABS, which stands for Blood cultures, Discard tube or Coagulation tube (blue), Plain tube or Serum tube with or without clot activator (red), Heparin tube (green), EDTA tube (purple), Additive tubes (grey), and Serum separator tube (gold or yellow). However, it's important to note that the acronym may vary slightly depending on the organization and country's practices.
