Exploring Additives in Gold Top Tubes for Phlebotomy in the United States

Summary

  • Gold Top tubes are commonly used in phlebotomy in the United States.
  • These tubes contain additives that help preserve the blood sample and facilitate testing.
  • The most common additives found in Gold Top tubes include clot activators, gel separator, and anticoagulants.

Introduction

Phlebotomy is the process of drawing blood for testing or donation. One of the most commonly used tubes in phlebotomy is the Gold Top tube, also known as a serum separator tube. These tubes contain additives that help preserve the blood sample and facilitate testing. In the United States, Gold Top tubes are used in clinical labs, hospitals, and home healthcare settings. In this article, we will explore the additives typically found in a Gold Top tube used for phlebotomy in the United States.

Clot Activators

One of the additives commonly found in a Gold Top tube is a Clot Activator. Clot activators are substances that promote the clotting of blood. When a blood sample is collected in a Gold Top tube with a Clot Activator, the blood will clot quickly, separating the liquid serum from the solid components of the blood. This allows for easier and more efficient testing of the serum. Some common types of clot activators used in Gold Top tubes include:

  1. Silica particles
  2. Glass particles
  3. Cellulose

Gel Separator

Another common additive found in Gold Top tubes is a gel separator. The gel separator is a substance that forms a physical barrier between the serum and the blood cells when the tube is centrifuged. As the tube spins, the gel moves to the top, separating the serum from the blood cells. This allows for clean and clear separation of the serum, making it easier to collect for testing. Some benefits of using a gel separator in Gold Top tubes include:

  1. Preventing contamination of the serum with blood cells
  2. Improving the quality of the serum sample
  3. Facilitating more accurate Test Results

Anticoagulants

In addition to clot activators and gel separators, Gold Top tubes may also contain anticoagulants. Anticoagulants are substances that prevent blood from clotting. While clot activators promote clotting for serum separation, anticoagulants are used in other types of blood tests that require an anticoagulated sample. Some common anticoagulants found in Gold Top tubes include:

  1. Heparin
  2. EDTA (ethylenediaminetetraacetic acid)
  3. Citrate

Conclusion

Gold Top tubes are a staple in phlebotomy in the United States, commonly used in clinical labs, hospitals, and home healthcare settings. These tubes contain additives that help preserve blood samples, facilitate testing, and ensure accurate results. The most common additives found in Gold Top tubes include clot activators, gel separators, and anticoagulants. Understanding the role of these additives is essential for healthcare professionals involved in phlebotomy and laboratory testing.
