Our point-of-collection (POC) diagnostics business, which generates gross margins that are well above our core laboratory service business, achieved a 37-percent revenue increase in 2001 and continued that strong performance with a 30-plus percentage gain in the first quarter of 2002. "In our laboratory services business we continued to gain new clients and completed a meaningful acquisition which significantly expanded our customer base and added testing capability in the rapidly growing pediatric lead-screening category. "Additionally, we made solid progress in the growth of our Clinical Trials Services (CTS) business which won more than $780,000 in new contracts during the first four months of 2002, a 160-percent increase over the same period of 2001. Our growing CTS business leverages MEDTOX's established competencies and infrastructure, and positions MEDTOX to tap into a $6 billion marketplace." MEDTOX Announces Formation of Clinical Trials Services Advisory Board "To further support the growth of our CTS business, we have established a Clinical Trials Services Advisory Board comprised of five highly experienced and talented professionals with an aggregate of more than 90 years' experience in clinical trials management, specialized testing, genomics and genetic engineering," Braun said.
