What 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 is the purpose of a multi draw needle?
Multiple draw needles are used with vacuum collection tubes. They allow the collection of blood into multiple vacuum collection tubes during a single venipuncture. They have a retractable sheath over the portion of the needle that penetrates the blood tube.
What color tube should be collected for a CBC?

What is the smallest needle to draw blood?
The smallest gauge, 25, is used primarily with pediatric patients. 1 The short needle length allows the phlebotomist to insert it at a shallow angle that can increase the ease of use. Usually, there is a safety device that slides over the needle to lock it after it has been used to minimize the risk of needle stick.
How do I make my veins better for blood draw?
Tips and Tricks for Accessing Problem Veins
- Get warm. When the body is warm, blood flow increases, dilating the veins and making them easier to find and stick.
- Use gravity. Increase blood flow to your arm and hand by letting gravity do the work.
- Hydrate. When the body is properly hydrated, veins become more dilated.
- Relax.

How does the autosampler work in a well?
The Autosampler transport mechanism uses an X-Z-theta robot to optimize the positioning of the sampling arm on the well plate. Once the sampling arm is positioned over the programmed sample position, the programmed sample volume is drawn by the metering device into the sampling needle.
