What this trial studies
The program invites adults in Guadeloupe to receive a standardized blood test for chlordecone and provides a multidisciplinary support pathway based on results. Blood samples are collected at participating local laboratories and analyzed by the Pasteur Institute of Guadeloupe, while biological samples are stored at the Karubiotec™ Biological Resource Center. Each participant receives their chlordecone result with a recommendation note and consenting individuals are contacted by a research assistant for a follow-up questionnaire. The referral physician explains the program, prescribes the test, and manages return of results as part of a ministerial free-testing measure.
Why it matters
Potential benefit: If successful, participants could learn their blood chlordecone level and receive personalized advice that may reduce their exposure over time.
How similar studies have gone: Population screening programs for persistent organic pollutants have been used to inform public health guidance, but direct evidence that screening alone lowers individual contaminant levels is limited.
