Allied health professionals are essential to quality medical care. Physicians depend on them for help in diagnosing diseases, treating and rehabilitating patients, and providing other essential medical and surgical services that affect the life and well-being of patients.

Depending on the position, some allied health professionals help monitor and evaluate diseases and disabilities. Others are directly and indirectly involved in health promotion, rehabilitation, health systems management, and dietary and nutritional services. These positions will become increasingly important due to the "team approach" necessary for future health care delivery.

The role of the allied health professional is expected to increase rapidly due to the need for specialists in home care and long-term care facilities. New technologies have miniaturized needed equipment for health care, allowing treatment in the home. Allied health professionals will also play an increasing role in educating people about health. It is anticipated that this profession will grow and receive increased attention for its contribution to health care access and delivery.

People who choose a career in the allied health field generally need good physical and mental health, emotional maturity, and good interpersonal skills. Careers which involve patient care require special understanding and tolerance to treat the sick and injured. Additionally, they must be able to appropriately resolve conflict and crisis situations.

Each allied health profession consists of workers with different types and levels of skill and knowledge. For example, the field of medical technology includes medical technologists, certified laboratory assistants, medical technicians and lab assistants.

Many health services establishments operate around the clock and need staff at all hours. Shift work is common in some occupations, while others work a more traditional 36- to 40-hour week. Allied health professionals involved in direct patient care must take precautions to guard against back strain from lifting patients and equipment, exposure to radiation and caustic chemicals, and infectious diseases such as AIDS, tuberculosis, and hepatitis.
