Special Procedures For Using Red Top Tubes In Phlebotomy

Phlebotomy is the process of drawing blood from a patient for various medical tests and procedures. It is a critical part of healthcare as it provides valuable information for diagnosis and treatment. One of the essential tools in phlebotomy is the collection tube, which comes in various colors indicating different additives and tests. The Red Top tube, also known as the serum tube, is a commonly used tube in phlebotomy. In this article, we will discuss the special procedures for using Red Top tubes in phlebotomy.

Overview of Red Top Tubes

Red Top tubes are used to collect blood samples for various tests that require serum, such as chemistry tests, serology tests, and blood bank testing. The tube does not contain any additives or anticoagulants, allowing the blood to clot naturally. Once the blood clots, the tube is centrifuged to separate the serum from the clot, which is then used for testing.

Common Tests using Red Top Tubes

1. Basic metabolic panel (BMP)

2. Comprehensive metabolic panel (CMP)

3. Liver function tests (LFTs)

4. Lipid panel

5. Cardiac enzyme tests

Special Procedures for Using Red Top Tubes

Correct Identification of Patient

Before collecting blood using a Red Top tube, it is crucial to correctly identify the patient to avoid any errors. Confirm the patient's identity by asking for their full name, date of birth, and any other relevant identifiers as per the hospital's protocol. Make sure to ask the patient to confirm their identity as well.

Properly Label the Tube

Once the patient's identity is confirmed, label the Red Top tube with the patient's full name, date of birth, and any other required information such as the date and time of collection. Properly labeling the tube is essential for accurate tracking of the sample and preventing any mix-ups.

Select the Correct Vein for Blood Collection

Choose the appropriate vein for blood collection based on the patient's age, medical condition, and the tests being performed. Ensure that the vein is visible, palpable, and suitable for Venipuncture. Proper vein selection minimizes the risk of complications and ensures a successful blood draw.

Perform Venipuncture

Before starting the Venipuncture procedure, clean the site with an alcohol swab to disinfect the area. Use a Tourniquet to help with vein visibility and ask the patient to make a fist to enhance venous filling. Perform the Venipuncture using a sterile needle and collect the required amount of blood into the Red Top tube.

Mix the Blood Gently

After collecting the blood into the Red Top tube, gently invert the tube several times to mix the blood with the Clot Activator. Mixing the blood adequately ensures proper clotting and prevents clot formation in the needle or tube, which can interfere with Test Results.

Allow the Blood to Clot

Place the Red Top tube in an upright position and allow the blood to clot for the recommended time, usually around 30 minutes. Clotting Time may vary depending on the test requirements, so refer to the laboratory guidelines for specific instructions. Clotting of the blood is essential for proper serum separation.

Centrifuge the Tube

Once the blood has clotted, place the Red Top tube in a centrifuge and spin it at the recommended speed and time to separate the serum from the clot. Centrifugation helps in obtaining clear serum for testing by causing the heavier cells to settle at the bottom of the tube while the lighter serum rises to the top.

Transfer the Serum to a Secondary Tube

After centrifugation, carefully remove the serum from the Red Top tube using a transfer pipette and transfer it to a secondary tube for testing. Be cautious not to disturb the clot at the bottom of the tube while transferring the serum to avoid contamination or hemolysis, which can affect the Test Results.

Store the Sample Properly

Once the serum has been transferred to the secondary tube, make sure to cap it securely to prevent any leakage or contamination. Label the secondary tube with the patient's information and store it at the required temperature until it is sent to the laboratory for testing. Proper storage ensures the integrity of the sample and accurate Test Results.

Conclusion

Using Red Top tubes in phlebotomy requires adherence to special procedures to ensure accurate and reliable Test Results. Correct patient identification, proper labeling of tubes, selecting the right vein, performing Venipuncture correctly, mixing the blood gently, allowing proper Clotting Time, centrifuging the tube, transferring serum carefully, and storing the sample appropriately are all essential steps in using Red Top tubes effectively. Following these procedures diligently helps in maintaining the quality of the sample and ensuring accurate Test Results for patient care.

Phlebotomists play a vital role in the healthcare system by collecting blood samples for diagnostic testing. By following the proper procedures in using Red Top tubes and other collection tubes, phlebotomists contribute to the accurate diagnosis and treatment of patients, ultimately improving healthcare outcomes.
