Procedure
1
Identify the patient by having him or her (or a guardian) state his full name.
2
Select the appropriate blood collection supplies. Establish the order of evacuated tubes if multiple
specimens are drawn.
3
Label all evacuated blood collection tubes with the patient's name and the time and date the speci-
men is drawn.
4
Position the patient with the elbow extended and the arm supported. Have the patient make a fi st,
but avoid vigorous pumping or other hand exercise.
5
Apply the tourniquet about 3 - 4 inches above the venipuncture site. Do not stop the blood fl ow
for more than one minute before the blood is drawn. If necessary, release and reapply the tourni-
quet.
6
Select the venipuncture site. The median antecubital and cephalic veins are most commonly
used.
7
Clean the venipuncture site with an alcohol pad, making one smooth, circular pass of the veni-
puncture site. Allow the skin to dry, to prevent hemolysis and to prevent the patient from having
a burning sensation when the needle is inserted. Do not touch the vein site after cleaning it.
8
Perform the venipuncture:
a
Wearing gloves, gently grasp the patient's arm near the venipuncture site, using the thumb to
draw the skin tight.
b
With the needle bevel facing up, line up the needle with the vein. Penetrate the skin and en-
ter the vein at an angle of approximately 15 - 30 degrees. Holding the fl ange of the needle
adapter, push the evacuated tube forward, allowing the back end of the needle to puncture
the stopper to engage the vacuum.
