Abstract: Kits are provided that can be used to determine a thromboxane B2 metabolite level and a creatinine level in a biological sample, particularly a human urine sample. This information can be used to optimize aspirin dosage in a patient. The present invention further includes calibrant preparations. In some embodiments, these calibrants comprise urine, particularly human urine that is identified in repeated trials to provide a consistent and reproduceable level of thromboxane B2 metabolite. As such, they function as control preparations that reduce error from intra-assay sampling measurements.

Abstract: Disclosed are unique methods for identifying the lowest, yet optimal, aspirin doses for patients. These methods are also characterized as having little to no aspirin-related side-effects. These methods may be used pre- as well as post-thrombotic event, and employs a patient's urinary thromboxane B2 metabolic levels (e.g., 11-dehydrothromboxane B2), to identify the patient's platelet activation level. A patient's urinary thromboxane B2 metabolic level is then used to calculate and appropriate and individualized treatment effective for utilizing platelet activation. Kits for utilizing this technique are also provided. In yet another particular aspect, the invention provides a method for utilizing a random urine sample obtained from a patient to determine whether a patient or particular individual's current dosage of aspirin is providing an adequate and appropriate level of inhibition of platelet activation levels, as compared to inhibition levels observed in individuals not taking aspirin.
