Order of Draw Importance for SST Tube Blood Sample Collection in the United States

Summary

• Proper order of draw is essential for accurate blood sample collection
• Using SST tubes requires specific steps to prevent contamination
• Following the correct order of draw helps maintain patient safety and ensures reliable Test Results

Introduction

Proper collection and handling of blood samples are crucial in the medical field to ensure accurate Test Results and patient safety. In the United States, clinical labs, hospitals, and home Healthcare Providers must follow strict protocols for collecting blood samples using SST tubes. Understanding the correct order of draw is essential to prevent contamination and ensure the reliability of the Test Results.

Order of Draw for SST Tubes

SST tubes, also known as serum separator tubes, are commonly used in medical labs for various blood tests. The proper order of draw for collecting blood samples using SST tubes is a critical step in the pre-analytical phase of testing. Following the correct order of draw helps prevent Cross-Contamination of samples and ensures the accuracy of Test Results.

Proper Steps for Collecting Blood Samples Using SST Tubes

1. Verify patient information: Before collecting a blood sample, confirm the patient's identity by checking their name, date of birth, and medical record number.
2. Select the appropriate vein: Choose a suitable vein for Venipuncture based on the patient's age, medical history, and the type of test being performed.
3. Cleanse the site: Use an alcohol swab to clean the puncture site and allow it to dry completely before proceeding with the Venipuncture.
4. Apply a tourniquet: Wrap a Tourniquet around the patient's arm to make the veins more visible and easier to access during the Venipuncture.
5. Perform the Venipuncture: Insert the needle into the vein at the correct angle and depth to collect the blood sample into the SST Tube.
6. Invert the tube: After filling the SST Tube with blood, gently invert the tube several times to ensure thorough mixing of the blood and the Clot Activator/gel separator.
7. Label the tube: Clearly label the SST Tube with the patient's name, date of birth, medical record number, and the time of collection to avoid any mix-ups in the lab.
8. Transport the sample: Store the labeled SST Tube in a biohazard bag or container and transport it to the lab for processing as per the lab's guidelines.

Importance of Following the Correct Order of Draw

Following the correct order of draw for collecting blood samples using SST tubes helps maintain patient safety and ensures the accuracy of Test Results. The order of draw is designed to prevent contamination of samples with additives present in subsequent tubes, such as anticoagulants or clot activators. Failure to follow the proper order of draw can lead to inaccurate Test Results and potential harm to patients.

Conclusion

Proper order of draw is essential for collecting blood samples using SST tubes in medical labs in the United States. By following the correct steps for sample collection, Healthcare Providers can maintain the integrity of the samples, prevent contamination, and ensure accurate Test Results. Adhering to the recommended order of draw helps protect patient safety and quality of care in clinical settings.
