Allied Health professionals are involved with the delivery of health or related services pertaining to the identification, evaluation and prevention of diseases and disorders; dietary and nutrition services; rehabilitation and health systems management, among others. Allied health professionals, to name a few, include dental hygienists, diagnostic medical sonographers, dietitians, medical technologists, occupational therapists, physical therapists, radiographers, respiratory therapists, and speech language pathologists.


Allied health may be defined as those health professions that are distinct from medicine and nursing.  


Allied health encompasses a broad group of health professionals who use scientific principles and evidence-based practice for the diagnosis, evaluation and treatment of acute and chronic diseases; promote disease prevention and wellness for optimum health, and apply administration and management skills to support health care systems in a variety of settings.

The professions included as allied health vary from country to country; however, estimates have suggested that as much as 60% of the U.S. healthcare workforce may be classified as allied health.Allied health plays an essential role in the delivery of health care and related services in the U.S. and throughout the world.

Allied health professionals are concerned with the identification, diagnostic evaluation, and treatment of acute and chronic diseases and disorders; provision of dietary and nutrition services; rehabilitation services; and the management and operation of health systems. Allied health professionals apply scientific principles and evidence-based practice in order to optimize patient or client outcomes.  Allied health professionals must also attend to the prevention of disease and the management of patients with chronic disease. Thus, the scope of allied health practice extends to the individual, the family, the community and to public education; many allied health professions specialize in the promotion of optimum function and health and the improvement of health-related quality of life. In addition, heath care administration and health systems management are important components of allied health.

Professions that are often listed as “allied health” include many of the well-known non-nurse, non-physician health care providers including audiologists and speech language pathologists; physical therapists, occupational therapists and respiratory therapists; diagnostic medical personnel (medical laboratory scientists, cytogenetic technologists, diagnostic molecular scientists, histotechnologists, and pathologists’ assistants); imaging specialists (radiographers, nuclear medicine technologists, and sonographers); nutritionists and dietitians; and physician assistants.  Others often included in allied health include dental personnel (dental hygienists and dental assistants); emergency medical personnel (EMTs, paramedics); exercise science professionals (athletic trainers, exercise physiologists, kinesiotherapists ); health information technologists; health educators (asthma educators, diabetes educators); counselors (genetic counselors, mental health counselors, family therapists); specialists in cancer diagnosis and treatment (medical physicists, medical dosimetrists, and radiation therapists); pharmacy personnel (pharmacy technicians and assistants) and other healthcare providers and support personnel, such as medical assistants. There are also a very large number of less well known health care professions generally considered as allied health. Table 1 lists many of the allied health professions, as well as the sources listing these as allied health professions.

Allied health educational programs seek to prepare competent allied health professionals and leaders for practice across multiple health care settings. Allied health educational programs are offered at a variety of postsecondary educational institutions.

There are a number of major allied health organizations in the U.S., including, but not limited to, the Association of Schools of Allied Health Professions (ASAHP).
