Venipuncture & Phlebotomy
BY VIDEO INSTRUCTION
Venipuncture
How the Test is PerformedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood. Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
PHLEBOTOMY PROCEDURE ILLUSTRATED DIFFERENT TYPES OF COLLECTION TUBES FOR PHLEBOTOMYDescribe and perform the venipuncture process including: Proper patient identification procedures. Proper equipment selection and use. Proper labeling procedures and completion of laboratory requisitions. Order of draw for multiple tube phlebotomy.

Patient care following completion of venipuncture. Safety and infection control procedures. Quality assurance issues. Identify the additive, additive function, volume, and specimen considerations to be followed for each of the various color coded tubes.

LABELING THE SAMPLE Automated systems may include labels with bar codes. YOU WILL LEARN ABOUT YOUR EQUIPMENT:Evacuated Collection Tubes - The tubes are designed to fill with a predetermined volume of blood by vacuum. The rubber stoppers are color coded according to the additive that the tube contains. Various sizes are available. Blood should NEVER be poured from one tube to another since the tubes can have different additives or coatings (see illustrations at end). Needles - The gauge number indicates the bore size: the larger the gauge number, the smaller the needle bore. Needles are available for evacuated systems and for use with a syringe, single draw or butterfly system. Holder/Adapter - use with the evacuated collection system. Tourniquet - Wipe off with alcohol and replace frequently. Alcohol Wipes - 70% isopropyl alcohol. Povidone-iodine wipes/swabs - Used if blood culture is to be drawn. Gauze sponges - for application on the site from which the needle is withdrawn. Adhesive bandages / tape - protects the venipuncture site after collection. Needle disposal unit - needles should NEVER be broken, bent, or recapped. Needles should be placed in a proper disposal unit IMMEDIATELY after their use. Gloves - can be made of latex, rubber, vinyl, etc.; worn to protect the patient and the phlebotomist. Syringes - may be used in place of the evacuated collection tube for special circumstances.
