  •  2026-04-24

Introduction:

In the realm of blood collection tube manufacturing, our turkey lines play a pivotal role in ensuring quality products for modern healthcare. Understanding the correlation between tube colors and specific phlebotomy tests is vital for healthcare professionals. In this article, we’ll actively explore the significance of tube colors and their associations with various tests in phlebotomy.

Decoding Tube Colors and Their Test Applications:

1. Red Tubes: These tubes collect serum for tests like blood chemistry and serology.

2. Light Blue Tube: With sodium citrate as their anticoagulant, blue-top tubes are essential for coagulation tests such as PT and aPTT.

3. Purple/Lavender Tubes: Tubes with lavender tops, containing EDTA, are ideal for CBC and blood typing.

4. Green Tubes: Equipped with heparin, green tubes facilitate plasma determinations in chemistry tests.

5. Gray Tubes: Containing sodium fluoride and potassium oxalate, gray tubes serve for glucose and alcohol determinations.

– Red tubes collect serum for blood chemistry and serology tests.

– Light blue tubes with sodium citrate are essential for coagulation tests like PT and aPTT.

– Purple/lavender tubes, containing EDTA, are perfect for CBC and blood typing.
