Aspirin Resistance 11 Dehydrothromboxane B2

Creatinine is a waste product produced by muscle metabolism and filtered by the kidneys into urine. This test measures creatinine in an 8-hour urine collection and reflects kidney filtration function. Creatinine levels help assess kidney health and are often used to calculate glomerular filtration rate (GFR), which indicates how well your kidneys filter waste. Low creatinine output may suggest reduced muscle mass or kidney disease, while the ratio of protein to creatinine helps assess kidney protein loss. This test is frequently ordered in patients with diabetes, high blood pressure, or known kidney disease.

This urine test measures 11-dehydro thromboxane B2, a breakdown product of thromboxane A2, a substance involved in blood clotting and platelet function. Elevated levels in urine indicate increased platelet activation and thromboxane production. This marker is useful for assessing cardiovascular risk, monitoring aspirin therapy effectiveness, and evaluating clotting disorders. High levels suggest your blood may be more prone to clotting, which increases risk for heart attack or stroke.
