Understanding Additives in Blood Collection Tubes: Anticoagulants, Clot Activators, and Gel Separators for Efficient Hospital Supply Management

Written By Natalie Brooks, BS, CPT

Summary

  • Blood collection tubes contain additives that help preserve the integrity of blood samples and facilitate diagnostic testing.
  • The most common additives in blood collection tubes include anticoagulants, clot activators, and gel separators.
  • These additives serve specific purposes such as preventing blood clotting, promoting clotting for serum separation, and enhancing sample quality for testing.

Introduction

Efficient hospital supply and equipment management are essential for the successful operation of medical facilities. In the United States, hospitals rely on a variety of tools and resources to ensure the delivery of quality healthcare services. One crucial aspect of hospital operations is blood collection, which requires the use of specialized tubes with various additives to maintain Sample Integrity. In this article, we will explore the most common additives in blood collection tubes and their purposes in the context of hospital supply and equipment management.

Anticoagulants

Anticoagulants are substances added to blood collection tubes to prevent blood from clotting. These additives are essential for preserving the liquid state of blood samples and ensuring proper analysis in laboratory testing. There are several types of anticoagulants commonly used in blood collection tubes, including:

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

Each type of Anticoagulant serves a specific purpose and is chosen based on the testing requirements of the blood sample. EDTA is commonly used for hematological studies, Heparin for coagulation studies, and citrate for tests that require plasma samples.

Clot Activators

Clot activators are additives that promote blood clotting by accelerating the coagulation process. These substances are used in blood collection tubes designed for serum testing, where the serum needs to be separated from the clot for analysis. Common clot activators include:

  1. Silica
  2. Thrombin
  3. Calcium

By activating the clotting process in blood samples, clot activators help facilitate the separation of serum from the clot, allowing for accurate testing of various blood components.

Gel Separators

Gel separators are additives used in blood collection tubes to create a physical barrier between the serum and the clot. These gel barriers help in separating the serum from the cellular components of blood, ensuring sample purity and integrity for testing. Gel separators are commonly made of substances like:

  1. Silicone
  2. Thixotropic gel
  3. Polymer gel

By forming a stable barrier between the serum and the cellular components, gel separators prevent contamination and ensure accurate testing results in clinical laboratories.

Conclusion

Effective hospital supply and equipment management require careful consideration of the additives used in blood collection tubes. Anticoagulants, clot activators, and gel separators play a crucial role in maintaining Sample Integrity and facilitating accurate diagnostic testing. Understanding the purposes of these additives is essential for ensuring the quality and reliability of laboratory results in medical facilities across the United States.
