Grey literature accesed through manual search, no restrictions were made by study design. Results: There is agreat variability in recommendations ranging from very restrictive to very lax. The vast majority were through clinical practice guidelines or opinion papers. The scientific paper identified, 2 were RCT, 3 non controlled trials, and one cross-sectional. Conclusions: Professional associations should use scientific arguments instead of corporative ones. The studies on adults don't allow to determine if the recommendation made by associations are evidence based. In the case of children, the studies and the recommendations give no information on what is the ideal age to perform the screening.
