The next step is to find a good vein to draw from:

  • Take a look at the anti-cubital area of the arm. You will need to wrap a tourniquet around the area about and inch to two inches above the area to help firm up the vein.
  • Press on the vein, if it feels springy then you’ve found a good one. If not, try looking at the other arm.
  • Once you locate the vein, wipe in a circular motion with an alcohol wipe, starting on the inside and working your way out. Then you may use the pointed corner of the alcohol wipe to point at the vein by setting it just below the area. It is important not to touch the area after you have wiped it. Release tourniquet until you actually going to draw.

Now carefully evaluate the vein to decide what gauge needle you will use. Your choices include:

  • 21 gauge, which is the largest
  • 22 gauge, which is a little smaller
  • The butterfly, which is a 23 gauge and is generally used for children or the elderly.

Now that you’ve chosen your needle, you may assemble it with a vacutainer. This device will automatically draw the blood into the tube once the tube is inserted. You are now ready to draw blood.

If you are using the butterfly, you must hook a syringe up to it. You can choose a 5 mL, 10 mL, etc. to draw the blood into. You will decide this based on how the patient’s vein looks and how much blood you will need. You will also need a transfer device to put the blood into the tubes.

*Remember to give your plunger a couple of pumps before using it to draw blood.

  • Now you will need to choose the proper tubes to draw based on your patients test needs. You must make sure to draw the blood into the tubes in the proper order. Each tube has a different additive in it and you do not want to contaminate one with another.

Order of draw:

      • Blue
      • Red, tiger top
      • Purple
      • Green
      • Gray

Before beginning, remember to “glove up”!

Follow these steps:

  • Reapply tourniquet
  • Look at the spot your alcohol wipe is pointing at, stabilize area so vein will not move and carefully insert needle.
  • Put first tube into vacutainer and check for blood flow.

*If you do not see blood in the tube, try pulling back a little.

  • Keep swapping tubes until you have filled them all.
  • Release tourniquet while last tube is filling.
  • Pull out needle, and activate safety shield.

  • Apply gauze to the area. Make sure to have patient keep pressure on the gauze while you are labeling the tubes. *Pressure will help reduce the risk of bruising.
  • Labeling is just as important as proper identification of the patient. Make sure you do it immediately, while the patient is watching.
    • Time, Date, and initial
    • Apply patient label
    • Do this for all tubes
  • Now you may apply a band-aid to the patient’s wound and they can be on their way!!
