Summary
Thromboelastography and standard coagulation tests show correlation but poor consistency. These methods cannot replace each other for assessing bleeding risk.
Area of Science:
- Clinical pathology
- Hemostasis and thrombosis research
Background:
- Coagulation function is critical for patient outcomes.
- Accurate detection methods are essential for clinical decision-making.
Purpose of the Study:
- To evaluate the correlation and consistency between thromboelastography (TEG) and traditional coagulation tests.
- To determine if these methods are interchangeable in clinical practice.
Main Methods:
- Retrospective analysis of 106 inpatients from ICU and gastroenterology departments.
- Collected and statistically analyzed clinical data from TEG and coagulation tests.
Main Results:
- TEG parameters (K, MA, α-Angle) correlated significantly with fibrinogen levels.
- TEG R time showed significant correlation with prothrombin time and activated partial thromboplastin time (APTT).
- Kappa values indicated poor consistency between TEG and coagulation tests for most parameters.
Conclusions:
- TEG and coagulation tests are significantly correlated but demonstrate poor consistency.
- These methods are not interchangeable and cannot replace each other.
- Current methods may not be sufficient for accurately assessing bleeding risk.

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
