serumrør

Serumrør are specialized laboratory containers used for collecting blood samples. Their primary function is to allow blood to clot and then separate into serum, which is the liquid component of blood without clotting factors, and the solid clot. The interior of a serumrør is typically coated with an anticoagulant or clot activator to facilitate this separation process. Common clot activators include silica particles or thrombin, which accelerate the clotting cascade. Some serumrør may also contain a gel separator layer at the bottom. This gel is inert and has a density between that of serum and blood cells. Once the blood is centrifuged, the gel forms a stable barrier between the serum and the blood clot, preventing re-mixing and making serum collection easier and cleaner. The choice of serumrør depends on the specific laboratory tests to be performed on the serum. Different additives are used to ensure the stability and integrity of various analytes present in the serum. These tubes are essential tools in medical diagnostics, research, and drug screening.
