Proper Handling and Storage Techniques for Blood Collection Tubes: Maintaining Sample Integrity for Accurate Test Results

Summary

• Proper handling and storage of blood collection tubes is crucial in maintaining the integrity of the samples for accurate Test Results.
• Different types of blood collection tubes have specific storage requirements to ensure the stability of the samples.
• Failure to follow proper handling and storage techniques can result in compromised Test Results and patient care.

Introduction

Handling and storing blood collection tubes properly in a medical laboratory setting is essential for ensuring accurate Test Results and maintaining patient safety. Improper handling and storage can lead to sample contamination, degradation, or inaccurate Test Results, ultimately affecting patient care. In this article, we will discuss the proper techniques for handling and storing various types of blood collection tubes in the United States.

Types of Blood Collection Tubes

There are several types of blood collection tubes used in clinical laboratories for different types of tests. Some common types include:

Serum Tubes

1. These tubes contain a Clot Activator and are used for tests that require serum, such as chemistry panels.
2. Should be inverted 5-10 times immediately after collection to ensure proper mixing of the blood and Clot Activator.
3. Allow the tube to clot for 30-60 minutes before centrifugation to separate the serum from the clot.
4. After centrifugation, the serum can be aliquoted into other tubes for further testing or storage.

EDTA Tubes

1. Contain the Anticoagulant ethylenediaminetetraacetic acid (EDTA) and are used for tests that require whole blood or plasma, such as hematology tests.
2. Invert the tube 8-10 times immediately after collection to ensure proper mixing of the blood and anticoagulant.
3. Should be stored at room temperature and protected from light to prevent sample degradation.
4. Centrifuge the tube within 2 hours of collection to separate the plasma from the cellular components of the blood.

Heparin Tubes

1. These tubes contain the Anticoagulant Heparin and are used for tests that require plasma, such as coagulation studies.
2. Invert the tube 8-10 times immediately after collection to ensure proper mixing of the blood and anticoagulant.
3. Centrifuge the tube within 2 hours of collection to separate the plasma from the cellular components of the blood.
4. Store the tube at room temperature until testing is performed.

Proper Handling and Storage Techniques

Proper handling and storage of blood collection tubes are crucial to ensuring the integrity and stability of the samples. Here are some key techniques to follow:

Handling Techniques

1. Always check the expiration date of the blood collection tubes before use.
2. Label each tube with the patient's name, date of birth, and collection time to prevent mix-ups.
3. Use aseptic techniques when collecting blood to prevent contamination of the sample.
4. Invert tubes several times immediately after collection to ensure proper mixing of the blood with additives.

Storage Techniques

1. Store blood collection tubes at the recommended temperature and conditions specified by the manufacturer.
2. Avoid exposure to extreme temperatures, light, moisture, or air as they can affect sample stability.
3. Use proper racks or holders to store tubes upright to prevent leakage or contamination.
4. Keep tubes organized and segregated based on test requirements to avoid mix-ups.

Consequences of Improper Handling and Storage

Failure to follow proper handling and storage techniques for blood collection tubes can have serious consequences, including:

Contaminated Samples

Improper handling can lead to sample contamination, resulting in inaccurate Test Results and potentially compromising patient care.

Degraded Samples

Inadequate storage conditions can cause samples to degrade, leading to unreliable Test Results and the need for sample recollection, increasing patient discomfort and Healthcare Costs.

Incorrect Test Results

If blood collection tubes are not handled and stored properly, it can result in incorrect Test Results, leading to misdiagnosis, inappropriate treatment, and potential harm to patients.

Conclusion

Proper handling and storage of blood collection tubes in a medical laboratory setting are essential for maintaining the integrity of samples and ensuring accurate Test Results. By following the recommended techniques for handling and storing various types of blood collection tubes, healthcare professionals can safeguard patient safety and provide high-quality care.
