Gold Top Blood Tube: Collection and Processing for Laboratory Testing
Summary
- A Gold Top blood tube is typically used to collect blood samples for various laboratory tests in the United States.
- The most common type of blood sample collected in a Gold Top tube is serum, which is the liquid component of blood that is left after clotting has occurred.
- These samples are processed in clinical labs to provide valuable information for diagnosing and monitoring patients' health conditions.
Introduction
When you go to a medical lab for blood work, you may notice that different colored tubes are used to collect your blood samples. One of the most commonly used tubes is the Gold Top tube, which is specifically designed to collect a certain type of blood sample. In this article, we will explore what type of blood sample is typically collected in a Gold Top tube in a medical lab in the United States.
What is a Gold Top Blood Tube?
A Gold Top blood tube, also known as a serum separator tube (SST), is a type of blood collection tube that contains a gel separator at the bottom. This gel is specially designed to separate the liquid portion of the blood, known as serum, from the cellular components of the blood, such as red and white blood cells and platelets.
Composition of a Gold Top Blood Tube
The Gold Top tube consists of the following components:
- Outer plastic or glass tube: to hold the blood sample
- Gel separator: to separate serum from blood cells
- Clot Activator: to promote blood clotting
- Gold-colored stopper: indicates the tube is used for serum testing
What Type of Blood Sample is Collected in a Gold Top Tube?
The most common type of blood sample that is collected in a Gold Top tube is serum. Serum is the liquid component of blood that is left after the blood has clotted and the cellular components have been removed. It contains a rich mixture of proteins, hormones, antibodies, and other substances that can provide valuable information about a person's health status.
Types of Laboratory Tests Using Serum Samples
Once the blood sample is collected in a Gold Top tube and processed in a clinical lab, the serum can be used for a variety of Diagnostic Tests, including:
- Basic metabolic panel (BMP): measures electrolyte levels, Blood Glucose, and kidney function
- Liver function tests (LFTs): assess liver health and function
- Lipid profile: evaluates cholesterol and triglyceride levels
- Thyroid function tests: assess thyroid hormone levels
- Autoimmune disease tests: detect antibodies that target the body's tissues
- Infectious disease tests: identify pathogens such as viruses and bacteria
Processing of Blood Samples in Clinical Labs
After the blood sample is collected in a Gold Top tube, it is transported to a clinical lab for processing. Here is an overview of the steps involved in processing blood samples in clinical labs:
Centrifugation
The first step in processing a blood sample in a Gold Top tube is centrifugation. The tube is placed in a centrifuge, a machine that spins the tube at high speeds to separate the serum from the blood cells. The gel separator in the tube acts as a barrier to prevent the serum from mixing back with the blood cells.
Aliquoting
Once the serum has been separated from the blood cells, it is carefully transferred into smaller tubes known as aliquots. These aliquots are used for different laboratory tests to ensure accurate and reliable results.
Analysis
The aliquots of serum are then analyzed using various laboratory techniques, such as immunoassays, chromatography, and molecular testing. The results of these tests provide valuable information about the patient's health condition and help Healthcare Providers make informed decisions about diagnosis and treatment.
Conclusion
In conclusion, a Gold Top blood tube is typically used to collect serum samples for laboratory testing in the United States. These serum samples contain a wealth of information that can help Healthcare Providers diagnose and monitor various health conditions. By understanding the purpose of the Gold Top tube and the type of blood sample it collects, patients can become more informed about the importance of blood work in their healthcare journey.
