Blood Collection Needle Color Guide
When it comes to drawing blood for medical purposes, using the right needle and color coding system is essential. Different needles are used for various purposes, and each color represents a different gauge size and needle type. In this comprehensive guide, we will break down the different blood collection needle colors and what they are used for.
Understanding Blood Collection Needle Colors
Before we delve into the specifics of each needle color, let's take a look at the general color coding system used for blood collection needles:
Yellow: This color is typically used for blood culture collections.
Light Blue: Light blue needles are used for coagulation tests, such as PT and PTT tests.
Red: Red needles are used for blood bank testing and serum chemistry tests.
Green: Green needles are used for routine chemistry testing, such as glucose and cholesterol levels.
Lavender: Lavender needles are used for CBC (complete blood count) tests.
Gray: Gray needles are used for blood glucose testing.
Yellow Blood Collection Needles
Yellow blood collection needles are typically used for blood culture collections. These needles are specifically designed to minimize the risk of contamination during blood culture sampling. The yellow color helps healthcare professionals quickly identify the needle for this specific purpose.

Light Blue Blood Collection Needles
Light blue blood collection needles are mainly used for coagulation tests, such as PT (prothrombin time) and PTT (partial thromboplastin time) tests. These needles contain sodium citrate, which helps preserve the blood sample for accurate coagulation testing.
For more information on coagulation tests and the use of light blue needles, you can refer to this resource.
Red Blood Collection Needles
Red blood collection needles are typically used for blood bank testing and serum chemistry tests. These needles are designed to facilitate the separation of serum from the blood sample, making them ideal for various types of blood tests.
