Definition of thromboplastin in English:

mass nounBiochemistry An enzyme released from damaged cells, especially platelets, which converts prothrombin to thrombin during the early stages of blood coagulation.
 Example sentencesExamples
-  A study in laboratory rats showed that ginsenosides increased coagulation time of thrombin and activated partial thromboplastin (aPTT).
 -  Indicated tests include a complete blood cell count with platelet count, a peripheral blood smear, and prothrombin and activated partial thromboplastin times.
 -  In the second stage, prothrombin is activated by thromboplastin to make thrombin.
 -  The atrial fibrillation group also had more hematologic tests done, including more prothrombin and partial thromboplastin times.
 -  The tests that are performed are a complete blood count, blood chemistry, prothrombin time, partial thromboplastin time, electrocardiogram, and chest x-rays.
