What type of test is typically performed using a gold top tube?

The gold top tube is commonly used for collecting samples that will be sent for chemistry tests. This tube contains a gel that serves as a separator, which helps in isolating the serum from the blood. In chemistry testing, the serum is required for the analysis of various substances, such as electrolytes, glucose, and enzymes. The design of the gold top tube optimizes the separation process after centrifugation, allowing for more accurate and reliable results in chemical analyses.

In contrast, other types of tests are generally performed using different tube colors due to the specific additives they contain. For example, blood glucose tests are typically conducted using a gray top tube that contains an additive to preserve glucose levels. Coagulation tests require a light blue top tube containing citrate, which prevents blood from clotting. Type and crossmatch tests are usually done using a red top tube or a pink top tube for compatibility tests, which do not utilize a gel separator.
