What Is a Medical Assistant? The Complete Career Guide

Medical Assistant Working

A medical assistant is a healthcare professional who works in outpatient clinical settings — physician offices, urgent care clinics, specialty practices, and hospital outpatient departments — performing both clinical and administrative tasks. Medical assistants are the operational backbone of most outpatient practices, keeping patient care moving efficiently.

What Medical Assistants Do

Clinical duties

  • Take vital signs (blood pressure, pulse, temperature, respiratory rate, oxygen saturation)
  • Draw blood (phlebotomy) and process lab specimens
  • Administer injections (vaccines, allergy shots, insulin, B12)
  • Perform EKGs and point-of-care tests (urinalysis, glucose, rapid strep)
  • Assist providers during examinations and minor procedures
  • Sterilize instruments and maintain infection control
  • Provide patients with care instructions

Administrative duties

  • Schedule appointments and manage patient flow
  • Document encounters in electronic health records (EHR)
  • Verify insurance and process prior authorizations
  • Handle phone triage and patient communications
  • Manage billing, coding, and claims processing

The dual clinical-administrative role is what makes medical assistants uniquely valuable. In a single shift, you might draw blood, give three injections, run an EKG, room fifteen patients, process a prior authorization, and handle a dozen phone calls.

Salary and Job Outlook

  • Median salary: $42,000/year nationally (BLS)
