Differences Between Serum Separator Tube (SST) and Plain Red Top Tube in Medical Labs

Summary

• Understanding the key differences between a serum separator tube (SST) and a plain Red Top tube is essential for proper handling in a medical lab setting.
• Proper handling procedures for SSTs involve specific centrifugation and storage techniques to ensure accurate Test Results.
• Strict adherence to laboratory protocols is crucial to maintain Sample Integrity and overall patient care in the United States healthcare system.

Serum Separator Tube (SST) vs Plain Red Top Tube

Medical laboratories play a crucial role in the diagnosis and treatment of patients in the United States healthcare system. Lab technicians are responsible for handling a variety of blood samples collected from patients, including those stored in serum separator tubes (SSTs) and plain Red Top tubes. Understanding the key differences between these two types of tubes is essential for ensuring accurate Test Results and maintaining Sample Integrity.

Components of SSTs and Plain Red Top Tubes

SSTs are specifically designed to facilitate the separation of blood components, such as serum and clotting factors. These tubes contain a gel barrier that, when centrifuged, separates the serum from the clotted blood. On the other hand, plain Red Top tubes do not contain a gel barrier and are used to collect whole blood samples for various tests that do not require serum separation.

Proper Handling Procedures for SSTs

When working with SSTs in a medical lab setting, it is essential to follow specific handling procedures to ensure accurate Test Results. These procedures typically involve the following steps:

1. Label the SST with the patient's information and the type of test to be performed.
2. Invert the tube gently several times to ensure proper mixing of the blood with the gel separator.
3. Centrifuge the tube at the recommended speed and duration to separate the serum from the clot.
4. Allow the tube to sit undisturbed for a few minutes to ensure complete separation of the serum and the gel barrier.
5. Carefully remove the serum using a pipette or other appropriate extraction method without disturbing the gel barrier.
6. Transfer the serum to a separate tube for analysis or storage as required.
7. Properly store any remaining sample for potential retesting if needed.

Proper Handling Procedures for Plain Red Top Tubes

While handling plain Red Top tubes may not involve the same level of complexity as SSTs, proper procedures must still be followed to maintain Sample Integrity. Some key handling procedures for plain Red Top tubes include:

1. Label the tube with the patient's information and the type of test to be performed.
2. Invert the tube gently to prevent clotting and ensure proper mixing of the blood sample.
3. Allow the tube to clot for the recommended time before centrifugation or testing.
4. Centrifuge the tube at the appropriate speed and duration to separate the serum from the clot, if necessary.
5. Handle the tube carefully to avoid disturbing the clot if serum separation is not required.
6. Extract the serum or perform the necessary tests according to laboratory protocols.
7. Store the tube and any remaining sample properly for potential retesting if needed.

Adherence to Laboratory Protocols

Strict adherence to laboratory protocols is crucial for ensuring the accuracy of Test Results and maintaining Sample Integrity in a medical lab setting. Lab technicians must follow established procedures for handling SSTs and plain Red Top tubes to prevent contamination, mislabeling, or other errors that could compromise patient care. By following proper handling procedures and maintaining high standards of Quality Control, medical labs can contribute to the overall success of the United States healthcare system.

Conclusion

Proper handling procedures for serum separator tubes (SSTs) versus plain Red Top tubes are essential in a medical lab setting in the United States. Understanding the key differences between these two types of tubes and following specific handling protocols is critical for maintaining Sample Integrity, ensuring accurate Test Results, and providing quality patient care. By adhering to established laboratory protocols and best practices, lab technicians can contribute to the success of the healthcare system and ultimately improve patient outcomes.
