The most common needle used for blood tests is a hypodermic needle, typically used in conjunction with a syringe for blood sampling.
While other blood collection systems exist (like vacuum tubes), the hypodermic needle remains a standard tool. Here's a breakdown:
- Hypodermic Needle: This is a hollow needle commonly used with a syringe to draw blood directly from a vein.
- Syringe: A syringe creates a vacuum, allowing blood to be drawn into the barrel.
As stated in the reference material, "The use of a hypodermic needle and syringe is the most common means of blood sampling."
