Which tube type is associated with tests like Chemistry, Lipids, Glucose, and RPR?

The gold or red marble top tube is associated with tests for Chemistry, Lipids, Glucose, and RPR. This tube contains a serum separator gel that facilitates the separation of serum from the blood cells after centrifugation. This property is particularly useful for a variety of serum chemistry tests, including those for lipids and glucose levels. The presence of the gel allows for a clear and reliable sample to be obtained without further processing, which is crucial for maintaining the integrity of the analytes being measured.

Tests like RPR (Rapid Plasma Reagin), which screens for syphilis, also rely on serum samples for accurate results. The gold or red marble top tube's design ensures that the samples can be easily processed while minimizing contamination risk, making it ideal for these analyses in clinical laboratories.
