A thought, conceived more than three decades ago by a pathologist, Dr. Pradip K. Desai, evolved into a start-up company as the Desai Laboratories. The goal was to indigenously develop and manufacture a comprehensive range of ready-made diagnostic reagents needed by clinical pathology laboratories. In 1976, the company was reorganized as Span Diagnostics with an emphasis on in-house R & D to develop more and more products, keeping the customer needs in focus and quality under constant vigil.
