What Types of Tests are Used in Functional Medicine?

Evaluating organ "function" versus organ "pathology" is one of the principles of functional medicine.

Tests may examine blood, hair, stool, urine, breath, and/or saliva. Common tests used by functional medicine practitioners check your nutritional status, digestive function, look for food and environmental allergies, investigate amino acid balance, energy metabolism function, hormonal balance, and more. The tests are designed to detect problems before more traditional tesing typically pinpoints pathological issues. With this approach, no specific disease is being looked for. Rather your doctor is looking to determine why your body is out of balance. 

Common functional medicine laboratory testing can include:  

  • Stool testing to evaluate digestive function
  • Blood testing to ascertain the presence of food allergies & sensitivities
  • Urine testing to evaluate intestinal permeability/íleaky gutí
  • Hair analysis to check various mineral levels
  • Blood testing to review vitamin status
  • Saliva testing to evaluate hormone status
  • Urine or blood testing to establish current amino acid levels
  • Testing to review levels of energy cycle metabolites
