Phlebotomist's Expertise On Blood Collection Tubes

Article

Apr 7

As a phlebotomist, one of the most important aspects of your job is knowing the different types of blood collection tubes and how to properly collect blood samples. Each tube is designed for specific tests and it is crucial that you understand the differences between them to ensure accurate results. In this article, we will discuss the expertise required for handling blood collection tubes.

Understanding Blood Collection Tubes

There are various types of blood collection tubes, each containing different additives to suit the needs of specific tests. Some of the common types of tubes include:

EDTA tube: Contains the anticoagulant ethylenediaminetetraacetic acid, used for testing blood cell counts, DNA, and blood typing.
Serum separator tube: Contains a gel that separates serum from cells after centrifugation, used for chemistry tests.
Heparin tube: Contains the anticoagulant heparin, used for plasma determinations in chemistry tests.

Proper Blood Collection Techniques

As a phlebotomist, it is essential to follow proper blood collection techniques to avoid errors and ensure accurate test results. Here are some key techniques to keep in mind:

Correctly Identifying Patients

Always make sure to correctly identify the patient before collecting blood samples to prevent mix-ups or errors. Use two patient identifiers, such as their name and date of birth, to verify their identity.

Selecting the Right Tube

Choose the appropriate blood collection tube based on the tests that need to be performed. Using the wrong tube can lead to inaccurate results and potentially harm the patient.

Proper Vein Selection

When selecting a vein for blood collection, choose a vein that is visible and palpable. Avoid veins that are bruised, scarred, or fragile.

Correct Order of Draw

Follow the correct order of draw when collecting multiple tubes of blood to prevent cross-contamination of additives. The recommended order of draw is typically blood culture tubes first, followed by tubes with additives.

Handling and Storage

Handle blood collection tubes carefully to prevent contamination or damage. After collection, store the tubes properly according to the manufacturer's instructions to maintain sample integrity.

Importance of Proper Training

Having expertise in blood collection tubes requires proper training and education. Phlebotomists must undergo comprehensive training to learn about the different types of tubes, proper collection techniques, and safety protocols.

Continuing education is also essential for phlebotomists to stay updated on new technologies and best practices in blood collection. Attending workshops, seminars, and completing certification courses can help enhance skills and ensure proficiency in handling blood collection tubes.
