Order of Draw and Additives | Blood Collection

This lesson covers the correct order of draw for blood collection. We also explain the additives in each tube as well as some of the tests that you would look to run with each tube.

We break down the phlebotomy order of draw and explain why it is that the proper order really matters to ensure that your patients are not misdiagnosed and get the proper treatment that they need.

We also include a helpful mnemonic and acronym to help you to be able to memorize this order of draw so that you can always get it right.

#OrderOfDraw #BloodTubes #ICUAdvantage

[ICUAdvantage]

NOTE: I did forget to mention, but typically the grey top tube tests will need to end up on ice immediately just like those select green top tube tests, in order to help preserve the values from when it was drawn from the patient!

[makeiahwilliams]

Easy way to remember the order is
You- Yellow
Better- Blue
Remember - Red tiger top gold
Gods - Green
Loving - Lavender
Grace -Gray

I got by the acronym Boys Should Stay Home Every Summer. B for blood culture tube, S for sodium citrate, S for serum tube, H for heparin, E for EDTA, and S for sodium fluoride/ potassium oxalate.

As a medical lab tech, the emphasis of how important the lab draws are is crucial for accurate lab testing. Integrity is everything. Loved this break down

[choppah]

Just took my NH exam and passed with a score of 420. Thank you for this detailed video, could not have done it without your help.

[vonquiambao]

I had these mnemonic for the proper order of draw. It is BCNHES (pronounced as benches)
B- blood culture (yellow)
C- citrate (blue)
N- no additives (red)
H- heparin (green)
E - EDTA (lavender)
S- sodium fluoride ( black or gray)

[elizabethmccown]

I learned the basic order from the acronym “bunny rabbits get pregnant” so blue red green purple.

[latinatech]

Thanks for this video. I've been drawing blood since 2006 and got my associate degree in medical assisting since 2010, and your video took me back to my classroom days. You explain like a professor. I also learn by understanding the WHY of the issue, not just memorizing colors since some tubes are interchangeable and also different Labs use different colors for different tests. This was very informative, thank you.

[Star_Kid]

This was so useful! I have my certification exam in a couple of weeks, and I was worried I wouldn't have a way to remember the order. This was so simple to understand, and I like the acronym. It's very easy to remember.

[rachaelsiddall]

I'm transitioning from phlebotomy in a plasma center to phlebotomy in a lab or Dr office. We only take two samples. I need to know all this for my interview to get hired at a lab or Dr office. This really really helped me. Thank you so much 😊

[ValerieKayParteeReid]

You're saving my life, sir! Ok, not literally, but you are DEFINITELY helping me through phlebotomy training! THANK YOU SO MUCH!!!💯💯💯

My top tip:
If you use a butterfly needle with a sodium citrate tube, you must take 2 tubes and discard the first one as it will be underfilled due to air in the line. It's the number 1 cause of underfilled citrate tubes in my lab.

The sodium citrate is best thought of as an actual reagent in the actual clotting tests. It differs from EDTA etc. because it's reversible with the addition of calcium, so as part of the clotting time tests a fixed amount of calcium is added to start the clotting and that's when the timer starts. This assumes a fixed concentration of citrate. If the tube is underfilled the concentration of citrate will be too high and the clotting times will be extended.

Blood Culture, Blue, Red, SST, Green, Lavender, Pink, and Grey, Other tubes

[TheDuddleyCo]

I used to work in the coagulation lab and I cannot emphasize enough the importance of mixing those blue tops so that the citrate mixes with the blood to stop clotting. The number of times I had to reject clotted samples was quite sad. I also had to explain to one nurse why I couldn't run an aptt on a clotted sample.

[maryraab]

I am currently a phlebotomy student. This was a very, very helpful video! Thank you so very much!

[Cateutopia]

I'm here because I'm thinking of taking a Phlebotomy course. This was very informative. Thanks so much. (I'm a retired Respiratory Therapist).

[sherlove]

I do not know how anyone can unlike this video. Made what could be complicated very simple. Thank you.

[ashleyf.]

literally the only reason I understand any of these tubes is all thanks to you. thank you thank you thank

[mariasevere]

I first want to thank God and say thank you for your time on doing this video. I pass my NHA exam today. I never really had time to study the order of draw or test to the tubes. It’s a lot of information. This acronym is so simple! I played the video until it was time to turn our phones off for testing. Yes! The why’s... is a must know for NHA! Thank you again! 🤗

I am entering the workforce after quite a few years and I needed this brush up! Thanks!
