Walgreen Co. said it won't sell an over-the-counter genetic test to consumers until the company that makes the test works out any regulatory issues with the U.S. Food and Drug Administration. The FDA said it had contacted Pathway Genomics about plans to sell a test designed to predict a person's risk for developing diseases or how they might respond to certain drugs. The company announced plans this week to sell its Insight Saliva Collection Kit through 6,000 Walgreens stores, the Wall Street Journal reports.
