The Importance of the Light Green Tube in Phlebotomy Procedures
Summary
- The light green tube in phlebotomy procedures is used for specific types of blood tests.
- This tube contains sodium Heparin as an Anticoagulant to prevent blood clotting.
- It is important to correctly identify and use the light green tube to ensure accurate Test Results.
Introduction
Phlebotomy procedures involve the collection of blood samples for testing and analysis. Different color-coded tubes are used to collect blood for various tests. One such tube is the light green tube, which serves a specific purpose in phlebotomy procedures in the United States.
The Purpose of the Light Green Tube
The light green tube, also known as a plasma separator tube (PST) or lithium Heparin tube, is used to collect blood samples for a variety of tests that require plasma. The tube contains an Anticoagulant called sodium Heparin, which prevents the blood from clotting during the collection process.
Why is Sodium Heparin Used?
Sodium Heparin is a commonly used Anticoagulant in phlebotomy procedures because it prevents the formation of blood clots by inhibiting the clotting process. This ensures that the blood sample remains in a liquid state, making it suitable for tests that require plasma instead of serum.
Tests that Require Plasma
The light green tube is typically used for tests that require plasma, such as:
- Chemistry panels
- Lipid profiles
- Thyroid function tests
- Glucose tests
How to Properly Use the Light Green Tube
It is essential to correctly identify and use the light green tube during phlebotomy procedures to ensure accurate Test Results. Here are some key steps to properly use the light green tube:
Verify Tube Color
Before collecting blood samples, make sure to verify that the tube being used is the light green tube. Using the wrong tube color can lead to inaccurate Test Results.
Invert the Tube
After collecting the blood sample, invert the light green tube several times to ensure that the Anticoagulant mixes adequately with the blood. This helps prevent clotting and ensures the stability of the plasma sample.
Centrifuge the Tube
Once the blood sample is collected, centrifuge the light green tube to separate the plasma from the red blood cells. This process allows for the isolation of the plasma, which can then be used for testing.
Conclusion
The light green tube plays a crucial role in phlebotomy procedures in the United States by allowing for the collection of blood samples for tests that require plasma. By understanding the purpose of the light green tube and following proper procedures for its use, healthcare professionals can ensure accurate and reliable Test Results for patients.
