Platelet Mapping: Advanced Hemostasis Testing

Platelet Mapping is a point-of-care viscoelastic hemostasis test that evaluates platelet function and clot formation. It involves measuring the impedance of whole blood clot formation under shear stress. Interpretation includes assessing the angle (alpha) representing the initial fibrin formation, maximum amplitude (MA) indicating overall clot strength, and shear elastic modulus (G) reflecting clot stiffness. Abnormal results suggest platelet dysfunction or other coagulation abnormalities, guiding diagnosis and treatment decisions in bleeding disorders, monitoring anticoagulant therapy, assessing surgical bleeding risk, and optimizing platelet transfusions.
