Dark Green Blood Tubes: The Importance of Sodium Heparin for Accurate Laboratory Test Results
Summary
- Dark green blood tubes are commonly used for phlebotomy in the United States.
- These tubes typically contain an additive called sodium Heparin, which helps prevent blood from clotting.
- The use of dark green blood tubes with sodium Heparin is important for accurate laboratory Test Results.
Introduction
When it comes to phlebotomy and blood collection, Healthcare Providers rely on the use of different colored tubes to collect and process blood samples. Each color tube contains specific additives that serve different purposes in preserving the integrity of the blood sample. In the United States, one of the commonly used tubes for phlebotomy is the dark green tube, which contains a specific additive to prevent blood clotting. In this article, we will explore the type of additive typically found in dark green blood tubes used for phlebotomy in the United States.
Dark Green Blood Tubes
Dark green blood tubes are easily distinguishable from other tubes due to their color. These tubes are used for collecting blood samples for various laboratory tests that require plasma or whole blood. The dark green color of these tubes indicates the presence of a specific additive that helps preserve the blood sample and prevent clotting during transportation and processing.
Additive in Dark Green Blood Tubes
The most common additive found in dark green blood tubes used for phlebotomy in the United States is sodium Heparin. Sodium Heparin is an Anticoagulant that works by inhibiting the activity of clotting factors in the blood, thus preventing the blood from clotting. This additive is essential for maintaining the integrity of the blood sample and ensuring accurate Test Results in the laboratory.
Importance of Sodium Heparin
Using dark green blood tubes with sodium Heparin is crucial for certain laboratory tests that require plasma or whole blood. Without the presence of an Anticoagulant like sodium Heparin, blood samples can clot and compromise the accuracy of Test Results. In addition, clotting can also interfere with the performance of automated analyzers used in clinical labs, leading to inaccurate readings and potential misdiagnoses.
Handling and Processing of Dark Green Blood Tubes
Healthcare Providers are trained to handle dark green blood tubes with care to ensure the integrity of the blood sample. After collection, the tubes are gently inverted several times to ensure proper mixing of the blood with the additive. The tubes are then labeled and transported to the laboratory for processing and analysis. It is essential to follow proper handling and processing procedures to avoid any pre-analytical errors that could affect the Test Results.
Conclusion
Dark green blood tubes with sodium Heparin are commonly used in the United States for phlebotomy and blood collection. The presence of an Anticoagulant like sodium Heparin is vital for preventing blood clotting and ensuring the accuracy of laboratory Test Results. Healthcare Providers must follow proper handling and processing procedures to maintain the integrity of the blood sample and provide reliable Test Results for patient care.
