Where else can they draw blood from?
Blood is most commonly obtained from the superficial veins of the upper limb. The median cubital vein, which lies within the cubital fossa anterior to the elbow, is close to the surface of the skin without many large nerves positioned nearby.
What is the best place to draw blood from?
median cubital vein
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. This reduces pain and discomfort for the patient.
What are other possible sites areas where venipuncture can be performed?
The most site for venipuncture is the antecubital fossa located in the anterior elbow at the fold. This area houses three veins: the cephalic, median cubital, and basilic veins (Figure 1).
Where is the most common site for venipuncture?
The most common site of venipuncture is the upper arm. The present study macroscopically and anatomically ascertained positional relationships between cutaneous nerves and veins in the cubital (aka antecubital) fossa in many cadaveric dissections to determine the risk of peripheral nerve injury during venipuncture.
What are the sites for capillary puncture?
The finger is usually the preferred site for capillary testing in an adult patient. The sides of the heel are only used in paediatric and neonatal patients. Ear lobes are sometimes used in mass screening or research studies.

What is the order of blood draw?
This is known as the Order of Draw.
- Blood Culture Tubes or Vials.
- Coagulation Tubes (Blue-Top Tubes)
- Serum Tubes without Clot Activator or Gel (Red-Top tubes)
- Serum Tubes with Clot Activator or Gel (Gold or Tiger Top Tubes)
- Heparin Tubes (Green-Top Tubes)
- EDTA Tubes (Lavender-Top Tubes)
What is the order of draw?
The “Order of Draw” is designed to eliminate the possibility of cross contamination that may result in erroneous results. It is based on CLSI Procedures for Collection of Diagnostic Blood Specimens by Venipuncture; Approved Standard Sixth Edition, October 2007.
What is the order of draw in venipuncture?
The recommended order of draw for plastic collection tubes is: First – blood culture bottle or tube (yellow or yellow-black top) Second – coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn.
What are the different types of blood draws?
Three popular methods of blood collection are:
- Arterial Sampling.
- Venipuncture Sampling.
- Fingerstick Sampling.
