What is an example of a test performed using the gray top tube?

• A. Complete blood count
• B. Blood culture
• C. Oral glucose tolerance test
• D. Coagulation test

Answer: (C)

The gray top tube is specifically designed for tests that require the analysis of glucose levels and other substances that can be affected by glucose metabolism. One of the primary uses of the gray top tube is for the oral glucose tolerance test, which assesses how well the body processes sugar and is a critical test in diagnosing diabetes and other conditions associated with insulin metabolism. This tube contains additives such as sodium fluoride and potassium oxalate, which help to prevent glycolysis, ensuring that glucose levels remain stable during the collection and transport phase. This preservation of glucose integrity is essential for accurate testing results in an oral glucose tolerance test. In contrast, the other types of tests mentioned, such as a complete blood count, blood culture, or coagulation tests, each have specific tubes suited for their respective requirements, primarily involving different types of additives and processing techniques.
