Final answer:
The color tube that would hold a glucose specimen for 24 hours is a gray top tube, which contains additives to preserve the glucose and inhibit the action of enzymes. It's important to follow the guidelines provided by the professionals conducting the test.
Step-by-step explanation:
The color tube that would hold a glucose specimen for 24 hours would depend on the specific laboratory protocol or test being conducted. However, in general, a gray top tube (also known as a potassium oxalate/sodium fluoride tube) is commonly used to collect and store a glucose specimen for an extended period of time, such as 24 hours.
These tubes contain additives that help preserve the glucose and inhibit the action of enzymes that could break it down over time. The gray top tube is specifically designed for glucose testing, ensuring accurate results even after 24 hours of storage.
It's important to note that the specific tube color may vary depending on the laboratory or healthcare facility, so it's always best to follow the guidelines provided by the professionals conducting the test.
