Applications Of Serum And Plasma Collection Tubes

Article

Apr 6

Welcome to our blog post discussing the various applications of serum and plasma collection tubes. Serum and plasma collection tubes are essential tools in the medical field for collecting blood samples for testing and analysis. These tubes come in different types and are specifically designed to preserve the integrity of the blood sample for accurate results. In this article, we will explore the different types of serum and plasma collection tubes and their specific applications in healthcare settings.

Difference between Serum and Plasma Collection Tubes

Before we delve into the applications of serum and plasma collection tubes, it is important to understand the difference between serum and plasma. Serum is the liquid component of blood that is collected after the blood has clotted, while plasma is the liquid component of blood that is collected before clotting occurs. The type of collection tube used will determine whether serum or plasma is obtained for testing.

Serum Collection Tubes

Serum collection tubes are designed to allow the blood sample to clot before the serum is separated from the blood cells. These tubes typically contain a clot activator and no anticoagulant. Once the blood has clotted, the tube is centrifuged to separate the serum from the blood cells. Serum collection tubes are commonly used for tests that require the measurement of substances present in the liquid portion of the blood.

Plasma Collection Tubes

Plasma collection tubes are designed to prevent blood clotting so that the liquid portion of the blood can be collected without interference from blood cells. These tubes contain anticoagulants, such as heparin or EDTA, to prevent clotting. Plasma collection tubes are commonly used for tests that require the measurement of substances that are present in the liquid portion of blood, such as electrolytes or enzymes.

Applications of Serum Collection Tubes

Serum collection tubes are used in a variety of medical tests and procedures to measure different substances present in the serum. Some common applications of serum collection tubes include:

Testing for cholesterol levels
Monitoring liver function
Measuring hormone levels
Testing for infectious diseases

Serum collection tubes are essential for accurate laboratory testing and play a crucial role in diagnosing and monitoring various medical conditions.

Applications of Plasma Collection Tubes

Plasma collection tubes are specifically designed to prevent blood clotting so that the liquid portion of the blood can be collected for testing. Some common applications of plasma collection tubes include:

Measuring electrolyte levels
Testing for blood disorders
Monitoring drug levels in the blood
Testing for genetic markers

Plasma collection tubes are essential for laboratory testing that requires the measurement of substances present in the liquid portion of blood without interference from blood cells.

Conclusion

Serum and plasma collection tubes are indispensable tools in the medical field for collecting blood samples for testing and analysis. Both types of collection tubes have specific applications and are essential for accurate laboratory testing. By understanding the differences between serum and plasma collection tubes and their applications, healthcare professionals can ensure that blood samples are collected and preserved properly for accurate test results.
