What is the most common method of venipuncture?

Venipuncture Sampling Venipuncture is the most common way to collect blood from adult patients. Collection takes place from a superficial vein in the upper limb, generally the median cubital vein; this vein is close to the skin and doesn’t have many large nerves positioned close by.

What is the order of draw in venipuncture?

The recommended order of draw for plastic collection tubes is:

  • Second – coagulation tube (light blue top). …
  • Third – non-additive tube (red top)
  • Last draw – additive tubes in this order:

Where is Antecubital?

The median cubital vein (antecubital vein) is a prominent superficial upper limb vessel. Its location is in the cubital fossa, on the anterior/flexor aspect of the elbow joint. This region of the upper limb is sometimes referred to as the antecubital area.

Where is the basilic vein located?

forearm The basilic vein originates on the medial aspect of the forearm at the wrist from the dorsal venous network of the hand. It runs superficially in the forearm and usually communicates with the cephalic vein via the median cubital vein at the elbow.

Which vein is used for phlebotomy?

Major arm veins used for phlebotomy. The median cubital vein is the larger and more stable vein and is preferred for venipuncture. The cephalic and basilic veins have a greater tendency to roll and veinpuncture may be more painful from these sites.

What is the H pattern in phlebotomy?

The “H- shaped” pattern is so named because the most prominent veins in this pattern- the cephalic, cephalic median, median basilic, and basilic veins- are distributed on the arm in a way that resembles a slanted H.

Which is the longest vein in the body?

Great Saphenous Vein Great Saphenous Vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle.

Which blood tube is drawn first?

EDTA tubes The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.

What is the difference between venipuncture and phlebotomy?

Phlebotomy specifically refers to the single-use needlestick for drawing blood specimens. Whereas venipuncture refers to the broader concept of entering the vein for either drawing blood or administering an IV for an extended period, phlebotomy is limited to blood-sample collection.

Why is syringe method used?

By using a syringe and needle to draw the patient’s blood, you can control the pressure and speed at which the blood is removed by varying the rate that you pull back on the plunger. A syringe draw is a much more appropriate technique for you to use with veins that easily collapse.

What color tubes are drawn last?

Collect citrate tube (blue top) last, after 20mL of blood has been withdrawn for other testing, or as waste. Just prior to drawing the blue top tube as the last tube, draw 1mL into a discard blue top tube to prevent cross contamination from the additive of previously drawn tubes.
