Understanding the Importance of the Serum Separator Tube (SST) in Blood Collection
Summary
- Serum samples are typically collected in a blood tube known as the serum separator tube (SST).
- The SST contains a gel that separates blood cells from serum during the centrifugation process.
- This type of tube is commonly used in clinical labs and hospitals for various Diagnostic Tests.
The Serum Separator Tube (SST)
When it comes to collecting blood samples for laboratory testing, there are several different types of blood tubes that are used depending on the specific requirements of the test. One of the most commonly used tubes for collecting serum samples in medical laboratory and phlebotomy procedures in the United States is the serum separator tube (SST).
The SST is a type of blood collection tube that contains a gel separator at the bottom. This gel functions to separate the blood cells from the serum during the centrifugation process. The serum, which is the liquid component of blood that does not contain blood cells or clotting factors, is collected at the top of the tube after centrifugation.
Components of the SST
The serum separator tube typically consists of the following components:
- Tube: The tube itself is made of plastic and comes in various sizes to accommodate different blood volume requirements.
- Stopper: The stopper at the top of the tube helps maintain a vacuum seal within the tube.
- Gel Separator: The gel at the bottom of the tube acts as a barrier between the blood cells and the serum.
- Anticoagulant: Some SST tubes may also contain an Anticoagulant to prevent blood from clotting during the collection process.
Uses of the SST
The serum separator tube is widely used in clinical laboratories and hospitals for a variety of Diagnostic Tests. Some common uses of the SST include:
- Chemistry Tests: The serum collected in the SST is often used for chemistry tests that measure various substances in the blood, such as glucose, cholesterol, and electrolytes.
- Immunology Tests: The serum can also be used for immunology tests that detect antibodies or proteins in the blood.
- Endocrine Tests: Hormone levels in the blood can be measured using the serum collected in the SST.
- Therapeutic Drug Monitoring: The serum can be used to monitor the levels of certain medications in the blood.
Conclusion
The serum separator tube is a vital component of blood collection in medical laboratory and phlebotomy procedures in the United States. Its ability to separate blood cells from serum makes it a valuable tool for conducting a wide range of Diagnostic Tests. Understanding the components and uses of the SST is essential for healthcare professionals working in clinical labs and hospitals.
