Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Medical and Clinical Laboratory Technicians

Testing human specimens using established laboratory techniques transfers directly to clinical laboratory testing that supports disease diagnosis and treatment.

How to prepare: Ask a target employer to evaluate your existing laboratory education, credentials, and military training against its technician entry requirements; some technician jobs accept an associate's degree.

What the civilian work involves
  • Conduct chemical analyses of body fluids, such as blood or urine, using microscope or automatic analyzer to detect abnormalities or diseases and enter findings into computer.
  • Analyze the results of tests or experiments to ensure conformity to specifications, using special mechanical or electrical devices.
  • Prepare standard volumetric solutions or reagents to be combined with samples, following standardized formulas or experimental procedures.
Civilian tools and software (examples)
  • MEDITECH software

Medical and Clinical Laboratory Technologists

Military specimen analysis for diagnosis, treatment, prevention, and medical research provides directly relevant experience for clinical laboratory technologist work.

How to prepare: Have your existing degree, laboratory education, and credentials evaluated against a target employer's technologist requirements before choosing additional coursework. Technologists typically need a bachelor's degree.

What the civilian work involves
  • Analyze samples of biological material for chemical content or reaction.
  • Analyze laboratory findings to check the accuracy of the results.
  • Conduct chemical analysis of body fluids, including blood, urine, or spinal fluid, to determine presence of normal or abnormal components.
Civilian tools and software (examples)
  • Commercial plate reader software
  • MEDITECH software

Notes & Sources

  • For both laboratory paths, check existing licenses and credentials with the intended state's licensing authority: some states require licensure or registration, and some require certification for licensure.
  • Employers may prefer certification; certification exam eligibility typically requires completion of an accredited education program.
