Aspirin is an anti-platelet drug that works to prevent heart attacks and strokes by reducing the production of thromboxane, the chemical that makes platelets sticky.
Although we can’t measure thromboxane directly, we can easily and non-invasively measure 11-dehydro thromboxane B2, its chemical biomarker’ using the AspirinWorks Test. In fact, the AspirinWorks Test is the only FDA-cleared test that accurately determines aspirin effect by measuring levels of this biomarker.
A low level of the biomarker in the urine means that aspirin is working to reduce thromboxane production. High levels of the biomarker may mean that your dosage of aspirin is not effective for decreasing the risk of a heart attack or stroke, and it’s time for you and your doctor to consider increasing the dose or changing your treatment strategy.
