Description:
Concerns have been raised recently regarding the validity and feasibility of using the chemically activated luciferase expression (CALUX) bioassay as a screening tool to measure dioxin exposure in large-scale epidemiologic studies. The objective of this research project was to validate the CALUX assay by comparison with the gold standard method, high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS), in 105 blood samples obtained from male Vietnam veterans during the period from 2001-2002. This grant was a follow-on to STAR Grant No. R825817.
