T2 and collaborators announce discovery of novel clot structure biology enabled by T2HemoStat
Date:1/9/2014

Lexington, MA, January 9, 2014 T2 Biosystems, a company developing direct detection products enabling superior diagnostics, announced that scientists from the University of Pennsylvania and T2 Biosystems have published a paper in Blood describing novel clot structure biology detected while testing T2 Bio's T2HemoStat. T2HemoStat is an innovative diagnostic tool for assessing blood clotting, platelet function, fibrinolytic activity and hematocrit measurements from a fingerstick blood sample in about 15 minutes. T2HemoStat uniquely detects millions of data points during a blood coagulation cascade. Researchers at the University of Pennsylvania, utilizing T2HemoStat, detected a signature of a novel clot structure, never before described in scientific literature. This clot structure involves a conformational change in red blood cell structure, termed polyhedrocytes. The presence of these structures could make stroke and heart attack victims less responsive to medications.

Blood clots are made up of fibrin, platelets and erythrocytes. Before now, little was known about the internal structure of contracted clots or the role that erythrocytes play in the contraction process. T2HemoStat is the first diagnostic method to enable the detection of this unique clot structure where erythrocytes are closely packed as polyhedra (polyhedrocytes) to form a seemingly impermeable barrier. This barrier means that these clot structures may be less susceptible to certain medications, called fibrinolytics, used to break up blood clots in the treatment of heart attacks and strokes.

"Physicians treating the millions of patients at risk for thrombosis and bleeding, including after surgery or trauma, are in need of a more convenient method to provide up to the minute results of key hemostatic parameters," commented co-author Douglas B. Cines, MD, Professor of Pathology and Laboratory Medicine and Director of the Special Coagulation Laboratory, Perelman School of Medicin
