Many of Deseret Biologicals products are specialized and one needs to understand their specific use and an individual's issues before using the products. We suggest that you get an exam by our doctor or you at least talk with our doctor via phone so we can best serve your needs. Although a phone call cannot substitute for being examined in some cases if an individual has had some testing or can answer some questions about their condition our doctor can generally recommend items that will serve that individual's symptoms well. When in doubt, please give us a call.
