Types Of Plasma Collection Tubes

Article

Apr 6

Introduction

Plasma collection tubes are important tools used in the medical field for collecting and storing blood samples. There are several different types of plasma collection tubes available, each designed for specific purposes and containing different additives to preserve the integrity of the sample. In this article, we will explore the various types of plasma collection tubes commonly used in healthcare settings.

1. EDTA Tubes

EDTA tubes are commonly used for collecting blood samples for hematology tests. The tube contains EDTA (ethylenediaminetetraacetic acid), which acts as an anticoagulant by binding to calcium ions in the blood and preventing it from clotting. EDTA tubes are typically lavender or purple in color to indicate their use for hematology testing.

Some common tests that require EDTA tubes include complete blood count (CBC), blood smear, and blood typing.

2. Citrate Tubes

Citrate tubes are used for collecting blood samples for coagulation tests. The tube contains sodium citrate, which acts as an anticoagulant by binding to calcium ions in the blood and preventing clotting. Citrate tubes are typically light blue in color to indicate their use for coagulation testing.

Some common tests that require citrate tubes include prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen levels.

3. Heparin Tubes

Heparin tubes are used for collecting blood samples for various tests, including chemistry and drug monitoring. The tube contains lithium heparin or sodium heparin, which acts as an anticoagulant by inhibiting thrombin formation. Heparin tubes are typically green in color to indicate their use for chemistry testing.

Some common tests that require heparin tubes include glucose levels, liver function tests, and therapeutic drug monitoring.

4. Serum Separator Tubes

Serum separator tubes are used for collecting blood samples for chemistry tests. The tube contains a gel separator that forms a barrier between the serum and the blood cells after centrifugation, allowing for easy separation of serum for testing. Serum separator tubes are typically red or gold in color.

Some common tests that require serum separator tubes include lipid profiles, kidney function tests, and liver function tests.

Conclusion

Plasma collection tubes play a crucial role in the accurate and reliable testing of blood samples in healthcare settings. Understanding the different types of plasma collection tubes and their uses is essential for healthcare professionals to ensure the integrity of blood samples and the accuracy of test results. By using the appropriate collection tubes for specific tests, healthcare providers can effectively diagnose and monitor various medical conditions.
