A health screener collects and organizes health information on behalf of an employer, community organization, or medical provider. As a health screener, your primary duties are to check a person’s vital signs, including blood pressure, height, and weight, and collect samples for analysis. You also use biometric equipment to test people’s heart rates. You must record all information and file it accordingly. Qualifications for this career can vary, but training and experience in the medical field are a must. Many find that skills gained in EMT training are sufficient.
