By method

Most test methods can be classified into one of the following broad groups:

• Patient observations, which may be photographed or recorded
• Questions asked when taking an individual's medical history
• Tests performed in a physical examination
• Radiologic tests, in which, for example, x-rays are used to form an image of a body target. These tests often involve administration of a contrast agent.
• In vivo diagnostics which test in the body, such as:
  • Manometry
  • Administering a diagnostic agent and measuring the body's response, as in the gluten challenge test, contraction stress test, bronchial challenge test, oral food challenge, or the ACTH stimulation test.
• In vitro diagnostics which test a sample of tissue or bodily fluids, such as:
  • Liquid biopsy
  • Microbiological culturing, which determines the presence or absence of microbes in a sample from the body, and usually targeted at detecting pathogenic bacteria.
  • Genetic testing
  • Blood sugar level
  • Liver function testing
  • Calcium testing
  • Testing for electrolytes in the blood, such as sodium, potassium, creatinine, and urea
