The Lavender Top Tube for CBC Testing
When you go to a healthcare facility for a complete blood count (CBC) test in the United States, you may notice that the phlebotomist uses a Lavender Top tube to collect your blood sample. This type of tube is specifically designed for CBC testing and contains additives that help preserve the integrity of the sample.
What is a CBC test?
A CBC test is a common blood test that provides important information about the types and numbers of cells in your blood. It can help diagnose a variety of conditions, including anemia, infection, and leukemia. The test measures different components of your blood, such as red blood cells, white blood cells, and platelets.
The Lavender Top Tube
The Lavender Top tube used for CBC testing contains a specific additive that is crucial for accurate Test Results. This additive is ethylenediaminetetraacetic acid (EDTA), a chelating agent that helps prevent blood clotting by binding to calcium ions in the blood.
The Role of EDTA
EDTA is essential for CBC testing because it keeps the blood sample from clotting, which could interfere with the results. Blood clots can alter the levels of certain blood cells and make it difficult to obtain accurate measurements. By preserving the integrity of the sample, EDTA ensures that the results are reliable and can be used for diagnostic purposes.
Other Lavender Top Tube Additives
In addition to EDTA, some Lavender Top tubes may also contain other additives to further stabilize the blood sample. These additives can vary depending on the specific brand and type of tube used, but their primary purpose is to ensure the quality of the sample and maintain the accuracy of the Test Results.
Conclusion
The Lavender Top tube used for CBC testing in the United States contains EDTA, which is a crucial additive for preventing blood clotting and preserving the integrity of the sample. This ensures that the results of the CBC test are accurate and reliable for diagnostic purposes.
