Prevent Cross Contamination

The reason the tubes are assigned this order is to prevent the cross-contamination of chemicals into other tubes which may cause errors in testing. This process is called reflux, which means the chemical can move from the tube and enter the needle. Once the next tube is activated it will have the previous chemical enter the tube, causing the contamination. You will need to study the tubes at your facility to determine which products are used for which test.

Order of Draw Bracelet

If the mnemonic device is not working, you may have heard of another option of buying an order of draw phlebotomy bracelet or other wearable. However, we do not recommend or encourage buying the order of draw phlebotomy bracelets because the OOD is something you need to know without relying on a bracelet.
