A collection of blood tests used to assess liver health typically requires a serum sample, collected in a tube with a red or gold stopper. These tubes may or may not contain a clot activator and gel separator. The serum, the liquid portion of blood remaining after clotting, is analyzed for various substances indicative of liver function, such as enzymes, bilirubin, and proteins.
Correct sample collection is crucial for accurate results. Using the appropriate tube ensures the integrity of the sample and minimizes interference with the delicate chemical reactions involved in laboratory analysis. This allows healthcare professionals to accurately assess liver function, diagnose liver diseases, and monitor the effectiveness of treatments. Standardized collection procedures contribute to consistent, reliable results across different laboratories and over time.
