Selecting the Correct Tubes

Choosing the right tubes for collecting blood samples is essential to ensure the accuracy of Test Results and maintain the integrity of the specimen. Different tests require specific types of tubes, such as serum separator tubes, plasma tubes, or Anticoagulant tubes. Follow these guidelines when selecting tubes:

1. Refer to the test requisition form to determine the required tubes for the tests being performed.
2. Check the expiration date on the tubes to ensure they are still VALID for use.
3. Label the tubes with the patient's information, including their name, date of birth, and medical record number.
4. Make sure that the tubes are the appropriate size for the amount of blood needed for the tests.

Obtaining the Blood Sample

Once the patient's information has been verified and the correct tubes have been selected, the phlebotomist can proceed with obtaining the blood sample. Follow these steps to collect an additional tube of blood during a phlebotomy procedure:

1. Prepare the equipment, including needles, syringes, and tourniquets.
2. Select the appropriate vein for Venipuncture and cleanse the site with an alcohol swab.
3. Position the patient's arm in a way that makes the vein accessible and secure a Tourniquet above the intended puncture site.
4. Perform the Venipuncture and fill the tubes in the proper order of draw to prevent contamination.
5. Invert the tubes gently to mix the blood with any additives and prevent clotting.
6. Label the tubes with the date and time of collection, the phlebotomist's initials, and any other required information.
7. Dispose of the used needles and other sharps in a designated sharps container.
