Key Differences Between Using a Gold Top vs. Red Top Tube for Blood Collection

Summary

• Gold Top tubes are used for serum testing, while Red Top tubes are used for plasma testing.
• Gold Top tubes contain a separating gel to separate serum from cells, while Red Top tubes do not contain any additives.
• The choice between using a Gold Top versus a Red Top tube depends on the specific tests being performed and the preferences of the healthcare provider.

Introduction

When it comes to blood collection for laboratory testing, Healthcare Providers have a variety of options to choose from. Two common types of blood collection tubes are the Gold Top tube and the Red Top tube. These tubes serve different purposes and are used for different types of tests. In this article, we will explore the key differences between using a Gold Top versus a Red Top tube for blood collection in the United States.

Gold Top Tube

The Gold Top tube, also known as a serum separator tube (SST), is a commonly used blood collection tube in healthcare settings. It is typically used for serum testing, which involves analyzing the liquid portion of blood after it has clotted. The Gold Top tube contains a separating gel that helps separate the serum from the cells in the blood sample. This gel acts as a barrier, preventing the cells from mixing with the serum during centrifugation. This separation is important for accurate Test Results, as any contamination from the cells could lead to inaccurate readings.

Uses

1. Biochemical tests
2. Hormone testing
3. Cholesterol testing
4. Liver function tests

Advantages

1. Separates serum from cells for accurate Test Results
2. Compatible with a wide range of laboratory tests
3. Easy to use and reliable

Disadvantages

1. More expensive than other types of blood collection tubes
2. May not be suitable for all types of testing
3. Requires proper handling to prevent contamination

Red Top Tube

The Red Top tube, also known as a plain tube, is another commonly used blood collection tube in healthcare settings. Unlike the Gold Top tube, the Red Top tube does not contain any separating gel or additives. It is used for plasma testing, which involves analyzing the liquid portion of blood without clotting. The blood sample in a Red Top tube is typically anticoagulated to prevent clotting and allow for the separation of plasma from cells during centrifugation.

Uses

1. Blood Glucose testing
2. Electrolyte testing
3. Drug Testing
4. Thyroid function tests

Advantages

1. Cost-effective option for blood collection
2. Suitable for a variety of laboratory tests
3. No additives that could interfere with Test Results

Disadvantages

1. No separating gel to separate plasma from cells
2. Can be more prone to contamination compared to Gold Top tubes
3. May not be suitable for tests that require serum instead of plasma

Choosing the Right Tube

When deciding between using a Gold Top versus a Red Top tube for blood collection, Healthcare Providers must consider the specific tests being performed and the preferences of the laboratory or healthcare facility. In some cases, the choice may be dictated by the requirements of the test itself, as certain tests are only compatible with serum or plasma samples. It is important to consult with the laboratory or healthcare provider to ensure that the correct tube is used for each test to avoid any potential errors or inaccuracies in the results.

Factors to Consider

1. Type of test being performed
2. Sample requirements (serum vs. plasma)
3. Cost considerations
4. Laboratory preferences

Best Practices

1. Follow proper blood collection procedures
2. Label tubes correctly with patient information
3. Handle and store tubes according to manufacturer guidelines
4. Consult with laboratory staff for specific test requirements

Conclusion

In conclusion, the choice between using a Gold Top versus a Red Top tube for blood collection in the United States depends on the specific tests being performed and the preferences of the healthcare provider. Gold Top tubes are typically used for serum testing, while Red Top tubes are used for plasma testing. Healthcare Providers must consider the advantages and disadvantages of each type of tube, as well as the requirements of the tests being performed, to ensure accurate and reliable results.
