Sst Tube vs Red Top Tube: Understanding the Key Differences
Summary
- The main difference between SST and Red Top tubes lies in their additive properties.
- SST tubes contain a gel separator that separates the serum from the blood cells, while Red Top tubes do not have this feature.
- Each tube is used for specific laboratory tests, with SST tubes being more commonly used for biochemical testing and Red Top tubes for blood clotting studies.
SST Tube vs Red Top Tube: Understanding the Key Differences
When it comes to collecting blood samples for laboratory testing, Healthcare Providers have a variety of tubes at their disposal. Two commonly used tubes are the Serum Separator Tube (SST) and the Red Top Tube. While both tubes may look similar at first glance, they serve distinct purposes in the realm of clinical lab work. In this article, we will delve into the key differences between SST and Red Top tubes, exploring their uses and advantages in the healthcare setting.
Serum Separator Tube (SST)
SST tubes, also known as gel tubes, are specially designed tubes that contain a gel separator. This gel acts as a barrier between the serum (liquid component of blood) and the blood cells (red and white blood cells, platelets). When a blood sample is collected in an SST Tube and centrifuged, the gel separates the serum from the blood cells, allowing for easy extraction of the serum for laboratory testing.
Red Top Tube
On the other hand, Red Top tubes do not contain any gel separator. These tubes are typically used for collecting blood samples that require clotting studies. When blood is collected in a Red Top tube, it is allowed to clot naturally before being centrifuged. The clotting process helps separate the serum from the blood cells, ensuring accurate Test Results.
Main Differences
Now that we have a basic understanding of how SST and Red Top tubes work, let's delve into the main differences between the two types of tubes:
- Additive Properties:
One of the primary differences between SST and Red Top tubes lies in their additive properties. SST tubes contain a gel separator that aids in separating the serum from the blood cells, making them ideal for biochemistry testing. In contrast, Red Top tubes do not have this gel separator and are primarily used for blood clotting studies.
- Tube Design:
Visually, you can differentiate between SST and Red Top tubes based on their color and design. SST tubes typically have a gold or tiger top color, indicating the presence of a gel separator. Red Top tubes, as the name suggests, have a plain red cap without any gel separator inside.
- Uses in Laboratory Testing:
Each tube is used for specific laboratory tests based on their unique properties. SST tubes are commonly used for biochemical testing, such as measuring glucose, cholesterol, and electrolyte levels. The gel separator ensures clean separation of serum, making it easier to perform these tests accurately. Red Top tubes, on the other hand, are typically used for coagulation studies, such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT).
Advantages of SST and Red Top Tubes
Both SST and Red Top tubes offer distinct advantages in the clinical laboratory setting:
- Efficiency:
SST tubes are known for their efficiency in separating serum from blood cells, reducing the risk of contamination and ensuring accurate Test Results. Healthcare Providers appreciate the convenience of using SST tubes for biochemistry testing, as they streamline the process of sample preparation.
- Clotting Studies:
Red Top tubes play a critical role in clotting studies, allowing Healthcare Providers to assess a patient's coagulation profile. By collecting blood in a Red Top tube and allowing it to clot, laboratory technologists can evaluate factors that affect blood clotting and overall hemostasis.
- Versatility:
While SST tubes are primarily used for biochemistry testing, they can also be employed for other types of laboratory tests, such as hormone assays and Drug Level Monitoring. Red Top tubes, on the other hand, are specifically designed for clotting studies and may not be as versatile as SST tubes.
Conclusion
In conclusion, understanding the key differences between SST and Red Top tubes is essential for Healthcare Providers working in the clinical laboratory setting. By recognizing the additive properties, tube design, and specific uses of each tube, clinicians can ensure accurate sample collection and reliable Test Results. Whether performing biochemistry testing with SST tubes or conducting clotting studies with Red Top tubes, having a clear understanding of these tubes' functionalities is crucial for delivering high-quality patient care.
