Arvind Kumar: The Science Behind Clot Retraction in Hemostasis
Arvind Kumar, Senior Resident at NIMS University, shared a post on LinkedIn:
“Determination of Clot Retraction
Introduction
Clot retraction is the process by which a freshly formed blood clot gradually decreases in size and squeezes out serum from the clot.
It occurs because of the contraction of platelets trapped within the fibrin meshwork.
The clot retraction test is used to assess:
- Platelet function
- Platelet count
- Integrity of fibrin formation
- Coagulation mechanism
Normally, after clot formation, the clot contracts and becomes smaller, leaving a clear serum layer around it.”
