Written By Natalie Brooks, BS, CPT

Summary

  • Understanding the different types of tubes used for blood tests in hospitals is essential for effective supply and equipment management.
  • Factors such as tube size, additives, and compatibility with testing equipment are crucial considerations when selecting the appropriate type of tube.
  • Proper training and education for staff on the use and handling of blood tubes are also important for maintaining quality and accuracy in testing results.

Introduction

Hospital supply and equipment management play a vital role in ensuring the smooth operations of healthcare facilities in the United States. One crucial aspect of this management is selecting the appropriate type of tube for blood tests. Blood tubes are essential tools used in collecting, processing, and storing blood samples for various Diagnostic Tests. With a wide range of tubes available in the market, healthcare facilities need to consider several key factors when making their selection to ensure accurate and reliable Test Results.

Types of Blood Tubes

There are several types of blood tubes commonly used in hospitals for different Diagnostic Tests. These tubes are color-coded based on the additives they contain and are designed to preserve the integrity of the blood sample. Some of the most common types of blood tubes include:

Serum Tubes

  1. These tubes are used for tests requiring serum samples.
  2. They are typically red or gold-topped tubes and do not contain any anticoagulants.
  3. Serum tubes are used for tests such as liver function tests, lipid profiles, and hormone levels.

Plasma Tubes

  1. Plasma tubes contain anticoagulants to prevent blood clotting and are used for tests requiring plasma samples.
  2. They are usually green-topped tubes and are used for tests such as glucose levels, electrolyte panels, and coagulation studies.

EDTA Tubes

  1. These tubes contain the Anticoagulant EDTA (ethylenediaminetetraacetic acid) and are used for tests requiring whole blood samples.
  2. They are typically lavender-topped tubes and are used for tests such as complete blood counts (CBC) and blood typing.

Heparin Tubes

  1. Heparin tubes contain the Anticoagulant Heparin and are used for tests requiring plasma samples.
  2. They are usually green-topped tubes and are used for tests such as electrolyte panels and arterial blood gas tests.

Key Factors to Consider

When selecting the appropriate type of tube for blood tests in a hospital supply and equipment management system, several key factors need to be taken into consideration:

Tube Size

  1. The size of the tube should be appropriate for the volume of blood required for the test.
  2. Using a tube that is too large may result in an insufficient blood sample, while using a tube that is too small may lead to hemolysis (rupture of red blood cells) and inaccurate Test Results.

Additives

  1. The additives present in the tube should be compatible with the specific test being performed.
  2. Using the wrong type of tube with incompatible additives can result in inaccurate Test Results or sample clotting.

Compatibility with Testing Equipment

  1. The selected tube should be compatible with the hospital's testing equipment and protocols.
  2. Using tubes that are not suitable for the equipment may lead to sample contamination, test errors, or equipment malfunction.

Staff Training and Education

Proper training and education for hospital staff on the use and handling of blood tubes are essential for maintaining quality and accuracy in Test Results. Staff should be educated on:

Proper Collection Techniques

  1. Staff should be trained on the correct techniques for collecting blood samples using the appropriate tubes.
  2. Improper collection techniques can lead to sample contamination, hemolysis, or other issues that may affect Test Results.

Storage and Handling

  1. Staff should be instructed on the proper storage and handling of blood tubes to maintain Sample Integrity.
  2. Improper storage or handling can result in sample degradation, affecting the accuracy of Test Results.

Quality Control Procedures

  1. Staff should be familiar with Quality Control procedures to ensure the accuracy and reliability of Test Results.
  2. Regular Quality Control checks should be performed to monitor the performance of testing equipment and detect any issues early on.

Conclusion

Selecting the appropriate type of tube for blood tests is crucial for hospitals to ensure accurate and reliable Test Results. By considering factors such as tube size, additives, compatibility with testing equipment, and staff training, healthcare facilities can effectively manage their supply and equipment systems to provide quality patient care. Proper selection and handling of blood tubes are essential steps in maintaining the integrity of blood samples and ensuring the accuracy of Diagnostic Tests.
