Heparin lithium is a commonly used blood anticoagulant, widely used in clinical testing. Its mechanism of action is that heparin can bind to antithrombin III, significantly accelerating its inactivation of serine proteases such as thrombin, thereby blocking the coagulation cascade reaction and effectively preventing blood clotting.
Heparin lithium is usually used in conjunction with inert separation gel (light green cap) in vacuum blood collection tubes. After blood collection and centrifugation, the separation gel will form a physical barrier between serum/plasma and blood cells, achieving rapid separation of plasma.

Heparin lithium has become the preferred anticoagulant for blood ion detection due to its unique chemical inertness. It only achieves anticoagulation by activating antithrombin and exists in the form of non-detectable lithium salt, which does not interfere with the determination of key ions such as potassium, sodium, and calcium. Compared to EDTA that chelates ions or heparin sodium that introduces exogenous sodium, it can restore the true concentration of blood ions to the greatest extent possible, ensuring accurate detection.
*Note: Lithium heparin can affect blood cell morphology and is not suitable for routine blood counts or white blood cell classification.
