11-Dehydrothromboxane B2 (or 11-dehydro-TXB2) is produced from the breakdown of thromboxane A2. It is released by activated platelets and urine levels of 11-dehydro-TXB2 can be used to monitor the response to aspirin therapy when used to prevent heart disease^[1] and in diseases where platelet activation is prominent.^[2]
