Quantifying platelet gel coagulation using Sonoclot and Thrombelastograph hemostasis analyzer

Area of Science:

• Biomedical Engineering
• Hematology
• Regenerative Medicine

Background:

• Platelet gel therapy is increasingly popular, yet lacks standardized methods for quantifying its structural integrity.
• Existing point-of-care technologies for clot analysis, such as TEG and Sonoclot, have not been thoroughly evaluated for platelet gel applications.

Purpose of the Study:

• To assess the applicability of TEG and Sonoclot as point-of-care devices for evaluating platelet gel clot strength and degradation.
• To determine if these technologies can provide quantifiable data on the structural integrity of platelet gel.

Main Methods:

• Bovine blood was processed into platelet-rich plasma and formed into platelet gel using varying thrombin concentrations.
• Platelet gel samples were analyzed using both TEG and Sonoclot devices.
• Statistical analysis, including a chi-squared test, was performed on the collected data.

Main Results:

• Out of 30 experiments, 15 TEG tests and 6 Sonoclot tests yielded valid results.
• TEG analysis produced valid clot signatures, whereas Sonoclot analysis resulted in invalid signatures for most samples.
• A chi-squared test indicated a statistically significant difference (p < 0.001) in the reliability of the two devices.

Conclusions:

• The Thrombelastograph Hemostasis Analyzer (TEG) is a potentially valid point-of-care tool for analyzing platelet gel clots.
• The Sonoclot device demonstrated unreliable performance in analyzing platelet gel clots in this study.
• Standardization of technology for quantifying platelet gels is crucial for advancing their clinical application.
