Using the correct technique for blood sample collection is crucial for accurate Test Results. Proper collection, handling, and labeling of specimens help prevent errors and ensure patient safety. It also maintains the integrity of the sample, which is essential for obtaining reliable results.

Steps for Collecting Blood Using a Yellow-Topped Tube

1. Patient Identification

1. Verify the patient's identity using two unique identifiers, such as their full name and date of birth.
2. Explain the procedure to the patient and obtain their consent before proceeding with the blood draw.

2. Gather Supplies

1. Assemble all necessary supplies, including the yellow-topped tube, needle, alcohol swabs, tourniquet, and adhesive bandages.
2. Check the expiration date on the tube and ensure it is within the acceptable range for use.

3. Prepare the Site

1. Select a suitable vein for blood collection and apply the Tourniquet approximately 3-4 inches above the puncture site to engorge the vein.
2. Cleanse the area with an alcohol swab and allow it to air dry before proceeding with the Venipuncture.

4. Perform Venipuncture

1. Put on gloves and palpate the vein to locate the best insertion point for the needle.
2. Insert the needle at a 15-30 degree angle with the bevel facing up and ensure proper blood flow into the tube.

5. Collect Blood Sample

1. Fill the yellow-topped tube with the required amount of blood, as specified by the laboratory for the tests being conducted.
2. Remove the Tourniquet and release the needle from the vein once the sample has been collected.

6. Label the Tube

1. Label the yellow-topped tube with the patient's full name, date of birth, the date and time of collection, and the phlebotomist's initials.
2. Ensure that the tube is securely closed to prevent leakage during transportation to the lab.

7. Post-Procedure Care

1. Apply pressure to the puncture site with gauze and secure it with an adhesive bandage to prevent bleeding.
2. Instruct the patient on post-procedure care, such as avoiding strenuous activities and keeping the site clean and dry.

Universal Precautions

Following universal precautions is essential during blood sample collection to prevent the risk of infection and contamination. This includes wearing appropriate personal protective equipment, such as gloves, and properly disposing of sharps and biohazardous waste.
