Thromboelastogram

Thromboelastography is a diagnostic method that allows you to obtain information about the properties of blood in real time, as well as about the changes that occur in it during the process of hemostasis.

The principle of operation is as follows: blood is mixed with a reagent and exposed to electric current. As a result of the interaction, a certain curve is formed that reflects changes in the properties of blood.

Thromboelastometry allows you to evaluate several blood parameters:

  1. Fibrin solubility characterizes the ability of blood to form clots. The greater the solubility of fibrin, the higher the risk of thrombosis.

  2. Viscosity - reflects the ability of blood to hold formed elements in place. The lower the viscosity, the easier it is for blood to flow.

  3. Strain - shows how much blood can stretch under the influence of force. The higher the deformity, the greater the risk of thrombosis.

  4. Platelet aggregation - reflects the degree of platelet aggregation, which is an important indicator of the risk of thrombosis.

  5. Clotting time - allows you to determine the rate of thrombus formation.

  6. Prothrombin time - shows how quickly the blood clots under the influence of the enzyme prothrombin.

  7. Fibrinogen - determines the concentration of a protein in the blood that is involved in the formation of a blood clot.



A thromboellastogram is an imaging tool that is used to determine the function and activity of a patient's blood in real time. Thromboelastograms show how the blood reacts to various stimuli such as thrombin, sodium citrate, calcium, collagen and other factors.

Thromboelastograms allow you to evaluate the time it takes for blood to begin to clot and how quickly it reaches its clotting limit. They can help determine if you have a bleeding tendency or excessive clotting, which can lead to thrombosis or other health problems.

Analysis of thromboellastrogram is usually carried out using specialized devices - hemostasis devices. Such machines are capable of measuring a number of parameters, such as retraction time (the time it takes for the blood to begin to clot), lysis time (the time it takes for the formed clot to break up), and clot stability. As a result of the analysis, a graphical curve is created, called a thromboelastogram or, alternatively, a reaction
