Lithium heparin blood tubes are designed for blood collection and are commonly used in clinical laboratories for various diagnostic tests. Heparin, an anticoagulant, is added to these tubes to prevent blood clotting by inhibiting thrombin and other clotting factors. The presence of lithium heparin ensures that the anticoagulant activity remains stable and consistent. These tubes are primarily used for tests that require plasma rather than serum, as heparin prevents clot formation while the blood is being processed. Plasma is the liquid portion of blood obtained after centrifugation and separation of cellular components. Tests performed on plasma include biochemical assays, enzyme assays, and certain specialized tests like arterial blood gas analysis. Lithium heparin tubes offer advantages such as rapid sample processing and reduced risk of clot formation compared to other anticoagulant tubes. They are widely used in clinical settings for a variety of diagnostic purposes, providing reliable results for patient care.
