What additive is present in the gold or tiger top tube?

• A. EDTA and clot activator
• B. Gel separator and typically serum
• C. Sodium citrate and serum
• D. Sodium fluoride and serum

Answer: (B)

The presence of a gel separator and typically serum in the gold or tiger top tube is significant because these tubes are designed to facilitate the separation of serum from the blood cells after centrifugation. The gel acts as a barrier that forms during the centrifugation process, allowing for the separation of serum, which is the liquid portion of the blood, from the cellular components. This is essential for many laboratory tests that require serum for accurate analysis. In addition, the gold or tiger top tubes often contain a clot activator which promotes clotting, aiding in the formation of serum after the blood sample is collected. This combination of additives and the physical characteristics of the tube makes it a popular choice for a multitude of serological tests.
