Guidelines for Proper Collection and Handling of Serum Separator Tubes in Medical Labs

Summary

• Serum Separator Tubes (SST) are an essential tool in medical labs for separating blood serum from blood cells for testing purposes.
• Proper handling and collection of SSTs is crucial to ensure accurate Test Results and maintain patient safety.
• There are specific guidelines that must be followed when collecting and handling SSTs in a medical lab setting in the United States to maintain Quality Control.

Introduction

Serum Separator Tubes (SSTs) are a common tool used in medical laboratories for the separation of blood serum from blood cells. These tubes contain a gel that acts as a barrier between the serum and the cells, allowing for easy separation during the centrifugation process. Proper collection and handling of SSTs are essential to ensure accurate Test Results and maintain patient safety.

Guidelines for Collecting Serum Separator Tubes

1. Proper Patient Identification

When collecting blood samples in SSTs, it is crucial to verify the patient's identity to prevent any mix-ups or errors. The following steps should be followed:

1. Ask the patient to state their full name and date of birth.
2. Check the patient's identification band or ask for a photo ID.
3. Confirm the information on the ID matches the information provided by the patient.

2. Correct Tube Selection

When collecting blood samples for serum testing, it is important to use the correct type of tube. SSTs come in different sizes and colors, so it is important to choose the appropriate tube for the test being performed. Here are some key points to consider:

1. Ensure the tube is labeled as an SST to indicate it contains a gel separator.
2. Check the expiration date on the tube to ensure it is still VALID for use.
3. Select the correct size tube based on the volume of blood needed for the test.

3. Proper Collection Technique

When collecting blood samples in SSTs, it is important to follow proper technique to prevent contamination and ensure accurate results. The following steps should be taken:

1. Clean the Venipuncture site with an alcohol swab and allow it to dry completely.
2. Use a sterile needle and syringe or vacuum tube system to collect the blood sample.
3. Invert the tube gently to mix the blood with the gel separator.

Guidelines for Handling Serum Separator Tubes

1. Labeling and Processing

After collecting blood samples in SSTs, proper labeling and processing are essential to ensure accurate Test Results. The following steps should be followed:

1. Label the tube with the patient's name, date of birth, and other required information.
2. Place the tube in a vertical position in a rack to allow proper clotting and separation.
3. Process the tube in a centrifuge according to the manufacturer's guidelines.

2. Storage and Transport

Once the blood sample has been processed in an SST, proper storage and transport are important to maintain Sample Integrity. The following steps should be taken:

1. Store the SST in a temperature-controlled environment according to the test requirements.
2. Transport the tube to the lab in a secure container to prevent breakage or leakage.
3. Avoid freezing or shaking the tube during storage and transport.

3. Quality Control and Documentation

Quality Control measures should be implemented to ensure the accuracy and reliability of Test Results from SST samples. The following steps should be taken:

1. Perform regular maintenance and calibration of centrifuges to ensure proper functioning.
2. Document all steps of the collection and handling process to maintain traceability and accountability.
3. Follow standard operating procedures and guidelines for the handling of SST samples.

Conclusion

In conclusion, proper collection and handling of Serum Separator Tubes (SSTs) are essential in a medical lab setting in the United States to ensure accurate Test Results and maintain patient safety. By following the specific guidelines outlined above, lab professionals can ensure the integrity of SST samples and provide quality care to patients.
