Human whole blood (left) is nearly indistinguishable from unclotted TrueClot® Blood Simulant (right)

TrueClot® Blood Simulant is a highly realistic simulated blood for training first responders in traumatic hemorrhage control, wound packing and the use of advanced hemostatic dressings. TrueClot Blood Simulant will form realistic simulated blood clots when used together with TrueClot Simulated Hemostatic Gauze on any task trainer or manikin-based wound simulator. Simulated clots for moulage or surgical training can be created using TrueClot Blood Simulant with TrueClot Clotting Solution.

TrueClot Blood Simulant comes as a premixed liquid or as a convenient concentrate that is easier to ship and store, but requires mixing in water.

TrueClot Blood Simulant and Blood Simulant Concentrate are safe and non-hazardous, wash from skin and clothing with soap and water and can be discarded in regular trash. The simulated blood will not clot unless it comes in contact with our Simulated Hemostatic Gauze or Clotting Solution and is stable for 3 years if stored at room temperature.
