J Expo Sci Environ Epidemiol 19:336-42. 2009..Whereas using specific gravity to correct for variable urinary output would be more robust. In addition, measuring specific gravity is relatively easy, does not require the use of chemicals, and the results are available instantaneously... - Biologic monitoring to characterize organophosphorus pesticide exposure among children and workers: an analysis of recent studies in Washington StateRichard A Fenske
