The Impact Of Lavender Top Tube On Sample Preservation In the Lab
When it comes to collecting and preserving blood samples in the laboratory setting, the type of tube used can have a significant impact on the quality and integrity of the sample. One commonly used tube for this purpose is the Lavender Top tube, which contains an Anticoagulant called EDTA (ethylenediaminetetraacetic acid). In this article, we will explore how the Lavender Top tube affects sample preservation in the lab and why it is a preferred choice for certain types of blood tests.
What is a Lavender Top tube?
A Lavender Top tube, also known as a purple top tube, is a type of blood collection tube that contains a specific additive to prevent the blood from clotting. The additive used in these tubes is EDTA, which works by chelating or binding to calcium ions in the blood, thereby preventing the coagulation process from occurring. This allows the blood sample to remain in a liquid state, making it suitable for a wide range of laboratory tests that require whole blood or plasma samples.
Why is the Lavender Top tube used for certain tests?
The Lavender Top tube is particularly well-suited for tests that require whole blood or plasma samples because it preserves the integrity of the sample and prevents clotting. Some of the common tests that require samples collected in Lavender Top tubes include:
- Complete blood count (CBC)
- Blood typing and crossmatching
- Hematology tests
- Genetic Testing
These tests rely on the accurate measurement of different blood components, such as red blood cells, white blood cells, platelets, and various proteins. Using a Lavender Top tube ensures that the sample remains stable and can therefore provide more reliable Test Results.
How does the Lavender Top tube affect sample preservation?
As mentioned earlier, the main function of the Lavender Top tube is to prevent blood clotting by binding to calcium ions in the blood. This process effectively stops the coagulation cascade from occurring, ensuring that the sample remains in a liquid state. By preserving the liquid state of the blood, the tube helps maintain the integrity of the sample and prevents any potential interference with the Test Results.
In addition to preventing clotting, the Lavender Top tube also helps preserve the structure and viability of certain blood components. For example, it is crucial for tests that require accurate measurement of red blood cell count, as clotted samples may lead to inaccurate results. The EDTA in the tube also prevents the breakdown of certain blood cells, such as white blood cells, which can be essential for specific tests.
Benefits of using Lavender Top tubes
There are several benefits to using Lavender Top tubes for blood sample collection and preservation in the lab:
- Prevents blood clotting: The main advantage of using a Lavender Top tube is that it prevents blood from clotting, ensuring that the sample remains in a liquid state.
- Preserves Sample Integrity: By maintaining the liquid state of the blood, the tube helps preserve the integrity of the sample and prevents any potential interference with Test Results.
- Stabilizes blood components: The EDTA in the tube stabilizes certain blood components, such as white blood cells, red blood cells, and platelets, ensuring more accurate Test Results.
- Compatible with a wide range of tests: Lavender Top tubes are suitable for a variety of laboratory tests that require whole blood or plasma samples, making them a versatile choice for sample collection.
Conclusion
In conclusion, the Lavender Top tube is an essential tool for ensuring the accurate collection and preservation of blood samples in the laboratory setting. By preventing blood clotting, preserving Sample Integrity, and stabilizing blood components, this type of tube plays a crucial role in obtaining reliable Test Results for a wide range of medical conditions. Understanding the benefits of using a Lavender Top tube can help laboratory professionals make informed decisions about sample collection and ensure the quality of Test Results.
