Common Blood Tests Using SST and Red Top Tubes in US Medical Laboratories
Summary
- SST Tube and Red Top tube are commonly used in medical laboratories in the United States for various types of blood tests.
- Specific types of blood tests that can be performed using an SST Tube include lipid profile, liver function tests, and basic metabolic panel.
- Red Top tube is typically used for blood clotting tests such as PT, INR, and PTT, as well as for blood typing and cross-matching.
SST Tube: Common Blood Tests
One of the primary types of tubes used in medical laboratories in the United States is the SST Tube, which stands for serum separator tube. This tube contains a gel that separates the serum from the blood cells once the blood sample has been centrifuged. The serum can then be used for various types of blood tests. Some common blood tests that can be performed using an SST Tube include:
- Lipid Profile: A Lipid Profile Test measures the levels of cholesterol and triglycerides in the blood. This test is important for assessing a person's risk of heart disease and monitoring their response to cholesterol-lowering medications.
- Liver Function Tests: Liver function tests, also known as hepatic function panel, measure the levels of proteins, enzymes, and bilirubin in the blood. These tests help evaluate the overall health of the liver and detect liver damage or disease.
- Basic Metabolic Panel: A basic metabolic panel (BMP) is a group of blood tests that measure various substances in the blood, such as glucose, electrolytes, and kidney function markers. This test provides information about an individual's overall health and can help diagnose conditions such as diabetes and kidney disease.
Red Top Tube: Blood Clotting Tests
Another commonly used tube in medical laboratories is the Red Top tube, which does not contain a gel separator like the SST Tube. This tube is typically used for blood clotting tests, as well as for blood typing and cross-matching. Some specific types of blood tests that can be performed using a Red Top tube include:
- Prothrombin Time (PT): PT is a blood test that measures how long it takes for blood to clot. This test is used to assess the function of the extrinsic pathway of blood clotting and monitor patients on Anticoagulant therapy.
- International Normalized Ratio (INR): INR is a standardized way of expressing PT results and is used to monitor patients on Anticoagulant therapy, such as warfarin. It helps ensure that patients are receiving the appropriate dose of medication to prevent blood clots.
- Partial Thromboplastin Time (PTT): PTT is a blood test that measures how long it takes for blood to clot through the intrinsic pathway. This test is used to diagnose bleeding disorders and monitor patients on Heparin therapy.
In addition to blood clotting tests, a Red Top tube can also be used for blood typing and cross-matching. Blood typing determines a person's blood group (A, B, AB, or O) and Rh factor (positive or negative), which is essential for blood transfusions. Cross-matching is a process that ensures compatibility between a donor's blood and a recipient's blood before a transfusion is performed.
Conclusion
Both SST tubes and Red Top tubes play a crucial role in the performance of various blood tests in medical laboratories in the United States. The specific types of blood tests that can be conducted using these tubes include lipid profile, liver function tests, basic metabolic panel, PT, INR, PTT, blood typing, and cross-matching. These tests provide valuable information about an individual's health status, help diagnose various medical conditions, and guide treatment decisions. Understanding the differences between these tubes and the tests they are used for is essential for Healthcare Providers to ensure accurate and reliable laboratory results for their patients.
