The 3.13% tri-sodium citrate solution is a proven medium in medical diagnostics, especially as an in vitro anticoagulant. The preparation is suitable for applications that require the prevention of blood clotting, such as in the collection of plasma or in the determination of blood sedimentation rate.

Tri-sodium citrate is an effective anticoagulant that prevents blood clotting by binding calcium ions that are crucial for the clotting process. Its use enables centrifugation of blood samples to obtain plasma without the formation of blood clots.

The mode of action of tri-sodium citrate solution is based on its ability to inhibit blood clotting. It binds and neutralizes calcium ions in the blood, inhibiting the clotting process. This enables safe handling and processing of blood samples for diagnostic purposes and ensures accurate and reliable results.
