Military Medicine is government run medical care within the military. The services pride themselves on being able to provide the best healthcare to the Airmen and their families. Having accurate medical tests and being able to properly diagnose illnesses accurately occurs between the laboratory and the physician. The physician is only as good at the information coming from the lab. Medical Laboratory specialists are that important and have an integral role in providing active duty military, reservists, veterans, and their family members with a proper diagnosis and treatment.

 In the military, our service members could be exposed to a variety of weapons and agents whether in a combat situation or on a humanitarian mission where pandemics are killing thousands. The state-of-the-art analysis provided by these experts not only helps prevent and treat disease, but is essential to detecting agents that indicate biological warfare.

The Medical Labratory Technician tests and analyzes specimens of human origin and other substances by established scientific laboratory techniques to aid in diagnosing, treating, and preventing diseases or to support medical research; and supervises medical laboratory activities.
