The order of draw should be observed when taking blood. The order of draw refers to the specific order in which the blood bottles should be attached when more than one blood sample is being taken. This avoids cross contamination between the additives inside the bottles. Colour coding and tube additives may vary but the simplified order recommended by WHO for vacuum blood bottles is shown in the table below:

Here are two videos showing examples of undertaking venepuncture. The first video on the left is more detailed and you may find this more useful if you'd like a more in depth overview of the procedure, particularly if you are new to the skill. The first video also shows how to undertake venepuncture using both a butterfly or 'winged' device, as well as using a needle and holder. As the second video is marked as age restricted you will need to click on the link to watch this directly on Youtube.
