Understanding the Importance of SST Red Top Tubes in Medical Lab Testing

Summary

• A "SST Red Top" tube is commonly used in medical labs in the United States to collect blood samples for various tests.
• Some specific tests that are typically performed using blood samples collected in a SST Red Top tube include chemistry panels, lipid panels, and glucose tests.
• This type of tube contains a gel separator that separates the blood cells from the serum, making it ideal for tests that require serum samples.

Introduction

When you visit a clinical lab or hospital in the United States for a blood test, you may encounter different types of tubes used to collect blood samples. One common type is the "SST Red Top" tube, which stands for serum separator tube with a red cap. This type of tube is specially designed to collect blood samples for specific tests that require serum samples.

Chemistry Panels

One of the most common tests performed using blood samples collected in a SST Red Top tube is a chemistry panel. This panel includes a variety of tests that measure different substances in the blood, such as electrolytes, liver enzymes, and kidney function markers. Some tests that are typically included in a chemistry panel are:

1. Electrolyte Panel: Measures the levels of minerals like sodium, potassium, and chloride in the blood.
2. Liver Function Tests: Checks the levels of enzymes and proteins produced by the liver, such as ALT, AST, and albumin.
3. Renal Panel: Assesses kidney function by measuring markers like creatinine and blood urea nitrogen (BUN).

Lipid Panels

Another common test that is often performed using blood samples from a SST Red Top tube is a lipid panel. This panel measures the levels of fats and cholesterol in the blood, which can help assess a person's risk for heart disease and other conditions. Some tests included in a lipid panel are:

1. Total Cholesterol: Measures the total amount of cholesterol in the blood.
2. HDL and LDL Cholesterol: Determines the levels of "good" (HDL) and "bad" (LDL) cholesterol in the blood.
3. Triglycerides: Measures the levels of a type of fat in the blood that can increase the risk of heart disease.

Glucose Tests

Glucose tests are also commonly performed using blood samples collected in a SST Red Top tube. These tests measure the levels of glucose (sugar) in the blood, which can help diagnose and monitor conditions like diabetes. Some common glucose tests include:

1. Fasting Blood Sugar (FBS): Measures the blood sugar levels after Fasting for at least 8 hours.
2. Random Blood Sugar: Checks the blood sugar levels at any time of the day, regardless of when the person last ate.
3. Oral Glucose Tolerance Test (OGTT): Involves drinking a sugary solution and then measuring blood sugar levels over time to test for diabetes.

Conclusion

Overall, the "SST Red Top" tube is a versatile tool used in medical labs in the United States to collect blood samples for a variety of tests. From chemistry panels to lipid panels to glucose tests, this type of tube with a gel separator is ideal for tests that require serum samples. The next time you need a blood test at a clinical lab or hospital, you may see this type of tube being used to collect your sample for analysis.
