Medical assistants help care for patients. They carry out routine treatments, run lab tests, and maintain office records.

Medical assistants may specialize in either clinical or administrative work, depending on the size of the medical practice or hospital. They do both in smaller clinics.

Clinical medical assistants

Medical assistants take medical histories and record patients' weight, pulse rate, blood pressure, and other vital signs. They explain treatments to patients and prepare them for exams. They also help the doctor during the exam.

Assistants also prepare laboratory specimens and perform basic lab tests. They instruct patients about medication and special diets.

Medical assistants’ duties vary by state. Some states allow medical assistants who have specialized training to draw blood or take x-rays. Additional duties include giving EKGs, changing bandages, and removing stitches.

After exams, assistants clean the room, dispose of used materials, arrange equipment, and sterilize used instruments.

Administrative medical assistants

Medical assistants also answer telephones, greet patients, escort them to exam rooms, and update medical records. They fill out insurance forms and schedule appointments. They also arrange for hospital admission and lab services.

Some assistants handle billing and bookkeeping. The size of the office determines how much time assistants spend on clerical duties. Assistants are supervised by doctors, other health workers, or office managers.

Ophthalmic medical assistants

Medical assistants who specialize in ophthalmic care do basic eye tests, fit frames, and teach people how to use contact lenses.

Podiatric medical assistants

Podiatric medical assistants work closely with podiatrists and make castings of feet. They also help podiatrists in surgery.
