Specific blood collection tubes are designated for various laboratory tests to ensure accurate results. For assessments of liver health, serum or plasma specimens are typically required. These are obtained using tubes with either a gold or red-topped stopper, signifying the presence of a clot activator and serum separator gel (gold top), or solely a clot activator (red top). After centrifugation, the serum or plasma separates, providing the appropriate sample for analysis.
Correct tube selection is crucial for reliable liver function testing. Utilizing the wrong tube can lead to hemolysis (destruction of red blood cells), clotting, or other interferences that may affect the accuracy of test results. This can lead to misdiagnosis or delayed treatment. The standardization of tube colors and additives ensures uniformity and consistency across different laboratories and healthcare settings, facilitating efficient and reliable diagnostic processes.
