These laboratory analyses, utilizing specific collection vials with a gold-colored top, are a crucial component of diagnostic testing. These tubes contain a serum separator gel and clot activator, which facilitate the rapid separation of serum from blood cells. This allows for efficient and accurate measurement of various analytes present in the serum, such as electrolytes, enzymes, and hormones. For example, a physician might order a comprehensive metabolic panel, requiring a specimen collected in this type of tube, to assess kidney function, liver function, and electrolyte balance.
The advantages of using these particular collection devices include their ability to provide a high-quality serum sample relatively quickly, minimizing interference from cellular components. This is essential for obtaining reliable results and ensuring accurate diagnoses. Historically, the introduction of these tubes represented a significant advancement in laboratory medicine, improving the efficiency and accuracy of serum-based testing compared to older methods. The resulting gains in speed and precision have directly benefited patient care and clinical decision-making.
