Using Citrate Plasma in Clinical Chemistry and Immunochemistry Tests: The Role of Phlebotomists

Summary

• Citrate plasma can be used in exceptional circumstances for some clinical chemistry and immunochemistry tests.
• Understanding when citrate plasma can be used and how it differs from other types of blood samples is essential for accurate Test Results.
• Phlebotomists play a crucial role in ensuring the proper collection and handling of citrate plasma samples in medical labs.

Introduction

Medical laboratories play a vital role in healthcare by providing valuable diagnostic information to Healthcare Providers. One essential aspect of laboratory testing is the type of specimen collected for analysis. While serum and plasma are commonly used in clinical chemistry and immunochemistry tests, citrate plasma can also be utilized in exceptional circumstances. In this article, we will explore the use of citrate plasma in medical labs, its advantages and limitations, and the role of phlebotomists in ensuring the accuracy of Test Results.

What is Citrate Plasma?

Citrate plasma is a type of blood sample that contains an Anticoagulant known as Sodium Citrate. This Anticoagulant prevents the blood from clotting by binding to calcium ions, thus allowing the plasma to be separated from the cellular components of blood. Citrate plasma is commonly used for coagulation studies to measure the clotting ability of blood.

Exceptional Circumstances for Clinical Chemistry and Immunochemistry Tests

While citrate plasma is primarily used for coagulation studies, there are exceptional circumstances where it can be used for certain clinical chemistry and immunochemistry tests. Some of the tests that may be performed using citrate plasma include:

1. Assessment of factor assays
2. Measurement of von Willebrand factor
3. Detection of lupus anticoagulant
4. Quantification of fibrinogen levels

Advantages of Using Citrate Plasma

There are several advantages to using citrate plasma for specific laboratory tests:

1. Stable Anticoagulant: Sodium Citrate is a stable Anticoagulant that does not interfere with most clinical chemistry and immunochemistry tests.
2. Patient Safety: Using citrate plasma reduces the risk of clot formation during sample collection and processing, ensuring accurate Test Results.
3. Cost-Effective: Citrate plasma is cost-effective and readily available, making it a practical option for certain laboratory tests.

Limitations of Using Citrate Plasma

While citrate plasma has its advantages, there are also limitations to consider when using this type of blood sample:

1. Interference with Some Tests: Citrate plasma may interfere with certain clinical chemistry and immunochemistry tests, leading to inaccurate results.
2. Specialized Handling: Citrate plasma samples require special handling to ensure accurate Test Results, including proper centrifugation and storage.
3. Limited Shelf Life: Citrate plasma has a limited shelf life compared to serum or plasma samples, requiring prompt testing and analysis.

The Role of Phlebotomists in Citrate Plasma Collection

Phlebotomists are healthcare professionals trained in the collection of blood samples for laboratory testing. When it comes to collecting citrate plasma samples, phlebotomists play a crucial role in ensuring the accurate collection and handling of samples. Some key responsibilities of phlebotomists in citrate plasma collection include:

• Proper Identification: Phlebotomists must accurately label citrate plasma samples to ensure traceability and prevent sample mix-ups.
• Skillful Collection: Phlebotomists must be skilled in the collection of citrate plasma samples to minimize the risk of sample hemolysis or contamination.
• Timely Processing: Citrate plasma samples must be processed promptly after collection to preserve the integrity of the sample and ensure accurate Test Results.

Conclusion

In conclusion, citrate plasma can be used in exceptional circumstances for certain clinical chemistry and immunochemistry tests. Understanding the advantages and limitations of using citrate plasma, as well as the role of phlebotomists in sample collection, is essential for accurate Test Results in medical laboratories. By following proper collection and handling procedures, Healthcare Providers can rely on the diagnostic information provided by citrate plasma samples for patient care.
