The Advantages of Using SST Tubes in Phlebotomy
In the field of phlebotomy, healthcare professionals rely on various tools and techniques to collect blood samples from patients. One common tool used in phlebotomy is the SST Tube, also known as the serum separator tube. SST tubes are often preferred by phlebotomists for several reasons, including their ease of use and efficiency in separating serum from blood cells. In this article, we will explore the advantages of SST tubes and why they are sometimes the preferred choice in phlebotomy procedures.
What are SST Tubes?
SST tubes are a type of blood collection tube that contains a gel separator at the bottom. This gel separator works by forming a barrier between the serum (the liquid component of blood) and the blood cells (such as red blood cells and white blood cells). When the tube is centrifuged, the gel separator moves to the top of the tube, effectively separating the serum from the blood cells.
Advantages of SST Tubes
Efficient Separation: One of the main advantages of SST tubes is their efficiency in separating serum from blood cells. This separation process is essential for various laboratory tests that require only the serum component of blood.
Easy to Use: SST tubes are simple to use, requiring minimal training for phlebotomists. The gel separator does the work of separating serum, eliminating the need for additional manual steps.
Time-Saving: Using SST tubes can save time during phlebotomy procedures. Since the gel separator automates the separation process, healthcare professionals can focus on other aspects of patient care.
Reduced Risk of Hemolysis: Hemolysis, the breaking down of red blood cells, can affect the accuracy of laboratory tests. SST tubes help reduce the risk of hemolysis by keeping blood cells separate from the serum.
When are SST Tubes Preferred?
While SST tubes offer several advantages, they are not always the preferred choice in every phlebotomy situation. Certain factors may influence the decision to use SST tubes or opt for alternative blood collection tubes. Here are some scenarios in which SST tubes are often preferred:
Routine Blood Tests
For routine blood tests that require serum, such as basic metabolic panels (BMP) or liver function tests, SST tubes are commonly used. The efficiency of SST tubes in separating serum makes them ideal for these types of tests, ensuring accurate results.
Time-Sensitive Samples
When time is of the essence, such as in emergency situations or urgent care settings, SST tubes can be preferred for quick and efficient blood sample collection. The ease of use and rapid separation process of SST tubes make them valuable in time-sensitive scenarios.
Pediatric Patients
For pediatric patients who may have difficulty sitting still or have smaller veins, SST tubes can be a preferred option. The efficiency of SST tubes in drawing blood quickly and accurately is advantageous when working with young patients.
High-Volume Phlebotomy
In settings where a high volume of blood samples needs to be collected efficiently, such as in hospitals or clinics with a large patient population, SST tubes are often preferred. The time-saving benefits of SST tubes can streamline the phlebotomy process in high-demand environments.
Alternatives to SST Tubes
While SST tubes have many advantages, there are situations where alternative blood collection tubes may be preferred. Depending on the specific requirements of laboratory tests or patient conditions, phlebotomists may opt for different types of tubes, such as:
EDTA Tubes
EDTA (ethylenediaminetetraacetic acid) tubes are commonly used for tests that require whole blood or plasma, rather than serum. These tubes are often preferred for hematology tests or DNA analysis that do not require serum separation.
Heparin Tubes
Heparin tubes contain an Anticoagulant that prevents blood clotting and is often used for tests that require plasma samples. These tubes are suitable for coagulation studies or certain chemistry tests that do not require serum separation.
Gel Barrier Tubes
Similar to SST tubes, gel barrier tubes contain a gel separator that aids in separating serum from blood cells. These tubes are used for specific tests that require serum separation but may have different gel formulations compared to SST tubes.
Conclusion
While SST tubes are not always the preferred choice in every phlebotomy scenario, their efficiency, ease of use, and time-saving benefits make them a valuable tool for healthcare professionals. By understanding the advantages of SST tubes and when they are best suited for use, phlebotomists can optimize their blood collection processes and ensure accurate laboratory results for patient care.
