Preservation of Blood Samples with Lavender Blood Tubes in Phlebotomy
Summary
- Lavender blood tubes are commonly used in phlebotomy procedures in the United States
- The additive present in lavender blood tubes is EDTA (Ethylenediaminetetraacetic acid)
- EDTA helps preserve blood samples by binding to calcium ions and preventing coagulation
Introduction
When it comes to phlebotomy procedures, healthcare professionals rely on various types of blood collection tubes to ensure accurate and reliable Test Results. One common type of blood tube used for Venipuncture is the lavender blood tube. In this article, we will explore the specific additive present in lavender blood tubes used in the United States and its role in preserving blood samples for clinical lab testing.
Lavender Blood Tubes in Phlebotomy
Lavender blood tubes are easily identifiable in the healthcare setting due to their distinctive purple color cap. These tubes are primarily used for collecting whole blood samples for hematology tests, such as complete blood counts (CBC) and Blood Smears. The lavender color of the tube indicates the specific additive present inside, which plays a crucial role in maintaining the integrity of the blood sample until it reaches the clinical lab.
EDTA as the Additive
The additive present in lavender blood tubes used for phlebotomy in the United States is Ethylenediaminetetraacetic acid, commonly known as EDTA. EDTA is a chelating agent that binds to calcium ions in the blood, preventing coagulation and maintaining the blood sample in its liquid form during transportation and processing. This ensures that the blood sample remains viable for various hematological tests that require whole blood specimens.
Preservation of Blood Samples
EDTA plays a crucial role in preserving blood samples for accurate testing in clinical laboratories. By chelating calcium ions, EDTA prevents the activation of the coagulation cascade and the formation of blood clots within the tube. This allows the blood sample to remain stable and suitable for analysis, even after prolonged storage or transportation to the lab. Additionally, EDTA helps maintain the integrity of cell morphology, making it easier for laboratory technicians to perform accurate differential white blood cell counts and other hematology tests.
Benefits of Lavender Blood Tubes with EDTA
Using lavender blood tubes with EDTA as the additive offers several advantages in the phlebotomy and laboratory testing process. Some of the key benefits include:
- Prevention of blood clotting: EDTA helps maintain the liquid state of the blood sample by preventing clot formation, ensuring reliable Test Results.
- Improved sample stability: The chelating properties of EDTA ensure that the blood sample remains stable and viable for testing over an extended period.
- Enhanced accuracy of Test Results: By preserving cell morphology and preventing clotting, lavender tubes with EDTA help improve the accuracy of hematology tests.
- Standardization of sample collection: The use of lavender blood tubes with EDTA allows for consistent and standardized blood collection practices across healthcare facilities.
Conclusion
In conclusion, the additive present in lavender blood tubes used for phlebotomy in the United States is Ethylenediaminetetraacetic acid (EDTA). EDTA plays a vital role in preserving blood samples for hematology testing by preventing coagulation and maintaining the stability of the blood sample. Healthcare professionals rely on lavender tubes with EDTA to ensure accurate and reliable Test Results in clinical labs. Understanding the importance of this additive can help improve the quality of patient care and diagnostic testing in hospitals and home healthcare settings.
