Why Do Phlebotomists Choose Lavender Top for Certain Samples
Introduction
As a phlebotomist, it is crucial to understand the different types of blood collection tubes and their uses. One commonly used tube in phlebotomy is the Lavender Top Tube. In this article, we will explore why phlebotomists choose Lavender Top Tubes for certain samples and the significance of this choice in the field of healthcare.
What is a Lavender Top Tube?
A Lavender Top Tube, also known as an EDTA tube, is a blood collection tube that contains the Anticoagulant Ethylenediaminetetraacetic acid (EDTA). This Anticoagulant works by binding to calcium ions in the blood, preventing the blood from clotting.
Features of Lavender Top Tubes:
Color: Lavender or purple-colored cap
Anticoagulant: EDTA
Uses: Hematology tests such as complete blood count (CBC), blood typing, and blood film
Why Do Phlebotomists Choose Lavender Top Tubes?
Phlebotomists often choose to use Lavender Top Tubes for certain samples due to the following reasons:
Preservation of Cell Morphology
Lavender Top Tubes are specifically designed for hematology tests that require the preservation of cell morphology. The EDTA Anticoagulant in these tubes helps maintain the integrity of blood cells, allowing for accurate analysis under the microscope.
Prevents Clotting
EDTA effectively prevents blood from clotting by binding to calcium ions, making it ideal for samples that require anticoagulation. This is particularly important for tests that involve cell counting and cell sizing, as clotting can lead to inaccurate results.
Stability of Sample
When collected in Lavender Top Tubes, blood samples remain stable for a longer period of time compared to samples collected in serum tubes. This stability allows for delayed processing of samples without compromising the quality of the results.
Compatibility with Hematology Analyzers
Many hematology analyzers are calibrated to work with Lavender Top Tubes, making them the preferred choice for hematology tests. Using the correct tube ensures that the analyzer can accurately interpret the sample and provide reliable results.
Common Tests Using Lavender Top Tubes
Lavender Top Tubes are commonly used for a variety of tests in the field of hematology. Some of the most common tests that require samples collected in Lavender Top Tubes include:
Complete Blood Count (CBC)
White blood cell count
Red blood cell count
Hemoglobin level
Platelet count
Blood Typing
ABO blood group typing
Rh factor testing
Blood Film Examination
Morphology of blood cells
Presence of abnormal cells
Best Practices for Using Lavender Top Tubes
To ensure accurate and reliable results, phlebotomists should follow best practices when using Lavender Top Tubes for blood collection:
Proper Mixing
It is essential to gently invert the Lavender Top Tube several times after collecting the blood sample to ensure proper mixing of the Anticoagulant with the blood. This helps prevent clotting and ensures accurate Test Results.
Correct Order of Draw
Phlebotomists should follow the correct order of draw when collecting blood samples to prevent carryover of additives from one tube to another. Lavender Top Tubes are typically drawn after tubes with clot activators or gel separators to avoid contamination.
Labeling and Identification
Properly labeling each Lavender Top Tube with the patient's information, date, and time of collection is crucial for sample identification and tracking. Accurate labeling helps prevent errors and ensures the integrity of the sample.
Storage and Transport
After collection, Lavender Top Tubes should be stored at room temperature and protected from light. It is important to transport the samples to the lab in a timely manner to prevent degradation of the sample and ensure accurate Test Results.
Conclusion
In conclusion, Lavender Top Tubes play a vital role in phlebotomy due to their ability to preserve cell morphology, prevent clotting, and ensure sample stability. Phlebotomists choose Lavender Top Tubes for specific tests in hematology to achieve accurate and reliable results. By following best practices for using Lavender Top Tubes, phlebotomists can contribute to the accuracy of diagnostic testing and patient care in healthcare settings.
