Blood sample was taken on May 10, 2016 with stated turn around time of 24 to 48 hours for results. Now is May 17, 2016 or 7 days later and NO results. The Purdy St. location in Easton, MD could not advise reason for delay and referred me to customer service at 1-800-745-0233. Customer service said results may not be available for the next 2 - 4 weeks!!!! Terrible, terrible service!!!!
