GAMCA stands for the Gulf Cooperation Council (GCC) Approved Medical Centers Association. It is an association that sets up medical centers in the Indian subcontinent region to provide medical tests and assessments for people who are planning to work in GCC countries such as Saudi Arabia, Qatar, and Kuwait. Some common synonyms for GAMCA include GCC medical tests, GCC employment medicals, GCC visa medicals, or GCC-approved medical tests. These terms are commonly used interchangeably to refer to the medical examination process that people must undergo before they can work in a GCC country. It is important to note that GAMCA is the official association responsible for overseeing and regulating the medical centers that conduct these tests.
