Health professionals attending the American Association for Family Physicians (AAFP) meeting at the Orlando Convention Center, Sept 21-23, 2016 who visit the DSM Nutritional Products Inc booth will be invited to complete an omega-3 dietary intake survey and have a drop of blood taken by finger stick by a health professional for blood fatty acid analysis. Dried blood samples on filter paper will be sent to an outside laboratory (OmegaQuant LLC) for analysis. Within 2 weeks, participants will receive an Omega-3 Index Test report by email from OmegaQuant LLC. After removing personal information, OmegaQuant LLC will share blood fatty acid and omega-3 dietary intake results with the sponsor.
