Proper Technique for Collecting Blood Samples Using Lavender Top Tubes: Guidelines for Accurate and Reliable Results

Summary

• Proper technique is essential when collecting blood samples for hematological testing in a medical laboratory.
• Using a Lavender Top tube is common practice for hematological testing in the United States healthcare system.
• Follow strict guidelines to ensure accurate and reliable Test Results.

Introduction

When it comes to healthcare in the United States, accurate and reliable Test Results are crucial for diagnosing and treating patients. One common test that is routinely performed is hematological testing, which involves analyzing the blood to assess various components such as red and white blood cells, platelets, and hemoglobin levels. In order to collect blood samples for hematological testing, proper procedures must be followed, including the use of specific types of collection tubes. One such tube is the Lavender Top tube, which is commonly used for collecting blood samples for hematological testing.

Benefits of Using Lavender Top Tubes

Lavender Top tubes are specifically designed for hematological testing and offer several benefits:

1. Contains EDTA (ethylenediaminetetraacetic acid) as an anticoagulant, which helps preserve the blood sample by preventing clotting
2. Provides accurate and reliable Test Results by maintaining the integrity of the blood sample
3. Easy to identify due to the distinct lavender-colored stopper, which helps prevent mix-ups in the laboratory

Proper Procedure for Collecting Blood Samples Using a Lavender Top Tube

1. Gather Necessary Supplies

Before collecting a blood sample using a Lavender Top tube, make sure you have the following supplies:

1. Lavender Top tube
2. Needle and syringe or butterfly needle
3. Alcohol swabs
4. Gauze pads
5. Bandage

2. Identify the Patient

Proper patient identification is critical to ensure that the blood sample is accurately labeled and attributed to the correct individual. Confirm the patient's identity by asking for their full name and date of birth, and verify this information against their medical records.

3. Prepare the Patient

Explain the procedure to the patient and address any concerns or questions they may have. Make sure the patient is in a comfortable position and ensure the arm to be used for blood collection is accessible and relaxed.

4. Perform Hand Hygiene

Before beginning the blood collection procedure, wash your hands thoroughly with soap and water or use an alcohol-based hand sanitizer to reduce the risk of contamination.

5. Locate a Suitable Vein

Identify an appropriate vein in the patient's arm for blood collection. The most common sites for Venipuncture are the median cubital vein, cephalic vein, and basilic vein. Apply a Tourniquet a few inches above the selected vein to make it easier to locate and access.

6. Cleanse the Site

Use an alcohol swab to clean the skin over the selected vein in a circular motion starting from the center and moving outward. Allow the skin to dry completely before proceeding with the Venipuncture.

7. Perform the Venipuncture

Once the skin is dry, perform the Venipuncture using the needle and syringe or butterfly needle. Insert the needle into the vein at a 15 to 30-degree angle and observe the flashback of blood into the syringe or tubing to confirm proper placement.

8. Collect the Blood Sample

Fill the Lavender Top tube with the required amount of blood based on the laboratory's guidelines. Invert the tube gently several times to ensure thorough mixing of the blood with the anticoagulant.

9. Remove the Needle and Apply Pressure

Once the blood sample has been collected, remove the needle from the vein and apply gentle pressure to the site with a gauze pad to stop any bleeding. Discard the needle into a sharps container following proper safety protocols.

10. Label the Tube

Properly label the Lavender Top tube with the patient's full name, date of birth, and the date and time of collection. Ensure the label is securely affixed to the tube to prevent it from coming off during transportation or processing.

11. Transport the Specimen

Place the labeled Lavender Top tube in a biohazard bag or container for transport to the laboratory. Follow any specific handling and transportation guidelines provided by the laboratory to ensure the integrity of the blood sample.

12. Document the Procedure

Record the details of the blood collection procedure in the patient's medical records, including the site of Venipuncture, the size of the needle used, the amount of blood collected, and any adverse reactions or complications that occurred.

Conclusion

Proper procedure is essential when collecting blood samples using a Lavender Top tube for hematological testing in a medical laboratory in the United States. By following strict guidelines and best practices, healthcare professionals can ensure the accuracy and reliability of Test Results, ultimately leading to better patient care and outcomes.
