Over time, what became widely known as the 'First Division Association' established a reputation for successfully representing the interests of senior managers and professionals in government. Given the public sector's fondness for acronyms, the moniker 'the First Division Association' evolved naturally into 'the FDA'.
FDA does not develop or test products before approving them. Instead, FDA experts review the results of laboratory, animal, and human clinical testing done by manufacturers. If FDA grants an approval, it means the agency has determined that the benefits of the product outweigh the known risks for the intended use.
