The Importance Of Proper Sample Storage In Phlebotomy Collection Tubes
Summary
- Proper sample storage in phlebotomy collection tubes is crucial for accurate Test Results.
- Various types of collection tubes are used for different tests, each requiring specific storage conditions.
- Understanding the importance of proper sample storage can help prevent errors and ensure reliable Test Results.
Introduction
Phlebotomy collection tubes are used to collect blood samples for diagnostic testing in healthcare settings. Proper handling and storage of these samples are essential to maintain their integrity and ensure accurate Test Results. In this article, we will explore how samples are stored in phlebotomy collection tubes and why it is important to follow proper storage protocols.
Types of Phlebotomy Collection Tubes
There are various types of phlebotomy collection tubes available, each designed for specific tests and requiring different storage conditions. Some common types of collection tubes include:
Serum Tubes
- These tubes are used for tests that require serum samples, such as chemistry tests.
- After collection, serum tubes are usually allowed to clot for a certain amount of time before centrifugation.
- Once the sample has been centrifuged, it is important to store the serum at the appropriate temperature to prevent degradation of analytes.
Plasma Tubes
- Plasma tubes are used for tests that require plasma samples, such as coagulation studies.
- These tubes contain an Anticoagulant to prevent clotting and are usually centrifuged soon after collection.
- Proper storage of plasma samples is essential to maintain the stability of analytes and ensure accurate Test Results.
EDTA Tubes
- These tubes contain EDTA as an Anticoagulant and are commonly used for hematology tests.
- EDTA tubes are typically stored at room temperature and should be gently inverted to mix the Anticoagulant with the blood after collection.
- It is important to store EDTA tubes properly to prevent degradation of cell morphology and ensure reliable Test Results.
Importance of Proper Sample Storage
Proper sample storage in phlebotomy collection tubes is crucial for maintaining the stability of analytes and ensuring accurate Test Results. Here are some reasons why proper sample storage is important:
Prevention of Sample Degradation
If samples are not stored correctly, analytes can degrade over time, leading to inaccurate Test Results. For example, exposure to light, heat, or air can affect the stability of certain analytes in a sample. Proper storage conditions help prevent sample degradation and ensure the reliability of Test Results.
Prevention of Contamination
Improper storage of samples can also lead to contamination, which can affect the accuracy of Test Results. Contamination can occur if samples are not stored in clean and sterile conditions, or if they come into contact with substances that can interfere with the testing process. Following proper storage protocols helps prevent contamination and ensures the integrity of samples.
Quality Control
Following proper sample storage protocols is an essential aspect of Quality Control in laboratory testing. By maintaining consistent storage conditions for samples, Healthcare Providers can ensure the reliability and accuracy of Test Results. Quality Control measures, such as proper sample storage, help prevent errors and ensure that patients receive accurate diagnoses and appropriate treatment.
Conclusion
Proper sample storage in phlebotomy collection tubes is essential for maintaining the integrity of samples and ensuring accurate Test Results. Different types of collection tubes require specific storage conditions to prevent degradation of analytes and contamination. Understanding the importance of proper sample storage can help Healthcare Providers prevent errors and deliver reliable Test Results to patients.
