What Is A Dark Green Top In Phlebotomy
Introduction
Phlebotomy, the process of drawing blood from patients for testing or donation, involves the use of various types of tubes to collect blood samples. One common type of tube used in phlebotomy is the Dark Green Top tube. In this article, we will explore what the Dark Green Top tube is, why it is used, and how phlebotomists can properly handle and process blood samples collected in this type of tube.
What is a Dark Green Top Tube?
A Dark Green Top tube, also known as a sodium Heparin tube, is a type of blood collection tube that contains the Anticoagulant sodium Heparin. Sodium Heparin prevents blood from clotting by inhibiting the action of clotting factors in the blood. The dark green color of the tube top is used to differentiate it from other types of tubes in the laboratory.
Composition of a Dark Green Top Tube
A Dark Green Top tube typically contains:
Sodium Heparin
Anticoagulant
Gel separator (in some tubes)
Barcode label for identification
Why is a Dark Green Top Tube Used?
Dark Green Top tubes are used in phlebotomy for a variety of reasons, including:
To collect blood samples for chemistry and Toxicology tests
To prevent blood from clotting during transport and processing
To obtain high-quality plasma samples for testing
Common Tests Using Dark Green Top Tubes
Blood samples collected in Dark Green Top tubes are commonly used for tests such as:
Electrolyte panels
Liver function tests
Drug monitoring tests
How to Properly Handle Dark Green Top Tubes
Proper handling of Dark Green Top tubes is essential to ensure the accuracy and reliability of Test Results. Phlebotomists should follow these guidelines when handling Dark Green Top tubes:
Collection Process
Verify patient identification before collecting blood samples
Choose appropriate vein for Venipuncture
Invert the tube gently to mix the blood with the anticoagulant
Transport and Processing
Label the Dark Green Top tube with patient information
Store the tube upright to prevent leakage
Transport the tube to the laboratory as soon as possible
Centrifugation
Centrifuge the tube according to laboratory guidelines
Allow the tube to rest for a few minutes after centrifugation
Transfer the plasma or serum to a separate tube for testing
Interpreting Test Results from Dark Green Top Tubes
Once blood samples collected in Dark Green Top tubes are processed and tested, phlebotomists and Healthcare Providers can interpret the results to make diagnostic and treatment decisions. Some key considerations when interpreting Test Results from Dark Green Top tubes include:
Reference Ranges
Each laboratory establishes its own reference ranges for tests using Dark Green Top tubes. Healthcare Providers should compare Test Results to these reference ranges to determine if values are within normal limits.
Clinical Significance
Understanding the clinical significance of Test Results is crucial for accurate diagnosis and treatment. Abnormal results from tests using Dark Green Top tubes may indicate underlying health conditions that require further evaluation and monitoring.
Conclusion
The Dark Green Top tube is an essential tool in phlebotomy for collecting blood samples for various tests. By understanding the composition of the tube, why it is used, and how to properly handle and process blood samples collected in Dark Green Top tubes, phlebotomists can ensure the accuracy and reliability of Test Results for patient care.
