Proper Use Of Serum Collection Tubes

Article

Apr 5

Serum collection tubes are an essential tool in the medical field for collecting and preserving blood samples for analysis. Proper handling and use of these tubes are crucial to ensure accurate test results and patient diagnosis. In this article, we will discuss the importance of using serum collection tubes correctly and provide guidelines for proper usage.

Why Proper Use of Serum Collection Tubes is Important

Proper use of serum collection tubes is essential for several reasons:

Prevents contamination: Using the wrong type of tube or improper handling can lead to contamination of the blood sample, which can affect the accuracy of test results.
Preserves sample integrity: Serum collection tubes are designed to preserve the integrity of the blood sample, ensuring that it remains stable until it is analyzed in the laboratory.
Ensures accurate results: Proper use of serum collection tubes helps to ensure that the test results are accurate and reliable, leading to proper diagnosis and treatment of patients.

Types of Serum Collection Tubes

There are several types of serum collection tubes available, each designed for specific tests and purposes. The most common types of serum collection tubes include:

Red-Top Tubes

Red-top tubes are used for general chemistry tests, such as blood glucose, cholesterol, and electrolyte levels. These tubes do not contain any additives and are used to collect serum for analysis.

Lavender-Top Tubes

Lavender-top tubes are used for collecting whole blood or plasma samples for hematology tests, such as complete blood count (CBC) and blood smears. These tubes contain an anticoagulant called EDTA, which prevents the blood from clotting.

Green-Top Tubes

Green-top tubes are used for collecting plasma samples for tests that require heparin as an anticoagulant, such as ammonia and STAT chemistry tests. The green-top tubes contain lithium heparin to prevent blood clotting.

Proper Handling and Use of Serum Collection Tubes

Proper handling and use of serum collection tubes are essential to ensure accurate test results. Here are some guidelines to follow when using serum collection tubes:

Labeling Tubes Correctly

It is crucial to label the serum collection tubes correctly with the patient's name, date of birth, and the date and time of collection. Proper labeling helps to prevent mix-ups and ensure that the results are attributed to the correct patient.

Choosing the Right Tube

It is important to select the appropriate type of serum collection tube for the specific test being performed. Using the wrong type of tube can lead to inaccurate results and affect patient diagnosis and treatment.

Proper Collection Technique

When collecting blood samples, it is essential to follow proper techniques to ensure a clean and uncontaminated sample. This includes disinfecting the collection site, using a clean needle and syringe, and avoiding hemolysis (rupturing of red blood cells).

Handling and Storage

After collecting the blood sample, it is important to handle and store the serum collection tubes properly. This includes gently inverting the tubes to mix the blood with any additives, storing them at the correct temperature, and transporting them to the laboratory promptly.
