Our study was developed to ascertain reference ranges of 11-dehydrothromboxane B2 (11-dhTXB2) in the urine of healthy pediatric subjects. Urine samples were analyzed using the AspirinWorks™ assay that measures levels of 11-dehydrothromboxane B2. 128 individuals (2 months to 18 years) were identified as healthy and not receiving aspirin. When adjusted as picograms/milligrams urine creatinine, there was a negative correlation between age and level of 11-dehydrothromboxane B2 (P = 0.0001). This study confirms a negative correlation between age and level of urinary 11-dehydrothromboxane B2 and provides a set of age-specific reference ranges.
