Proper Storage of Blood Collection Tubes: Special Instructions for Each Type

Summary

• Proper storage of blood collection tubes is essential for maintaining the integrity of samples.
• Each type of blood collection tube has specific storage requirements to preserve the quality of the sample.
• Following the recommended storage instructions can help ensure accurate Test Results and reliable diagnostic information.

Introduction

When it comes to collecting blood samples for medical testing, it is crucial to follow proper storage instructions to maintain the integrity of the samples. Different types of blood collection tubes have specific storage requirements to ensure the quality of the sample is preserved until it reaches the laboratory for analysis. In this article, we will discuss the special storage instructions for blood collection tubes and why it is important to adhere to these guidelines.

Why Proper Storage is Important

Proper storage of blood collection tubes is essential for maintaining the integrity of the samples and ensuring accurate Test Results. When samples are not stored correctly, it can lead to degradation of the sample, which can affect the reliability of the diagnostic information provided by the laboratory. By following the recommended storage instructions for each type of blood collection tube, Healthcare Providers can ensure that the samples remain stable until they are analyzed.

Types of Blood Collection Tubes

1. Plain Tubes
2. EDTA Tubes
3. Serum Separator Tubes
4. Gel Tubes

Special Storage Instructions for Blood Collection Tubes

Plain Tubes

Plain tubes, also known as red-top tubes, are used for collecting serum samples. To store plain tubes properly:

1. Keep the tubes at room temperature before and after collection.
2. Store the tubes upright to prevent leakage.
3. Avoid freezing the samples, as this can cause hemolysis.

EDTA Tubes

EDTA tubes are used for collecting whole blood samples for hematological testing. To store EDTA tubes properly:

1. Invert the tubes several times after collection to ensure proper mixing of the anticoagulant.
2. Store the tubes at room temperature or refrigerated, but do not freeze.
3. Protect the samples from light, as some tests may be sensitive to light exposure.

Serum Separator Tubes

Serum separator tubes, also known as tiger-top or gold-top tubes, are used for collecting serum samples that require separation of the serum from the clot. To store serum separator tubes properly:

1. Allow the tubes to clot for 30 minutes before centrifugation.
2. Centrifuge the tubes according to the manufacturer's instructions.
3. Store the separated serum at room temperature or refrigerated, but do not freeze.

Gel Tubes

Gel tubes are designed to separate serum or plasma from cells using a gel barrier. To store gel tubes properly:

1. Collect the sample according to the manufacturer's instructions.
2. Do not freeze the samples, as this can affect the integrity of the gel barrier.
3. Store the tubes at room temperature or refrigerated until analysis.

Conclusion

Proper storage of blood collection tubes is essential for maintaining the quality of samples and ensuring accurate Test Results. Each type of blood collection tube has specific storage instructions that must be followed to preserve the integrity of the sample until it reaches the laboratory for analysis. By adhering to these guidelines, Healthcare Providers can help ensure that patients receive reliable diagnostic information based on accurate Test Results.
