  EXA Test® is a reliable noninvasive method using rapidly metabolizing sublingual epithelial cells under Analytical Scanning Electron Microscopy, (ASEM,) an Energy Dispersive X-Ray Analysis, (EXA,) to reflect fast tissue changes of vital mineral electrolytes.

  EXA Test® provides results that correlate with heart, muscle, and  deep organ tissue. EXA results do not correlate with blood. EXA provides information not available through blood or serum tests. Essential mineral electrolytes are most prominent in epithelial tissue not in blood: for example, 99% of magnesium is found in soft tissue and only 1% is found in blood.

EXA Test® results assists the physician with diagnosis, treatment protocols, management of heart disease and other complex conditions where mineral electrolyte deficiency or imbalance is confirmed.

Quality of Life studies are published in peer review journals.

  • Healthcare professionals perform an office based non-invasive
    60 second specimen collection. We provide the specimen collection kit.
  • The specimen is sent to IntraCellular Diagnostics for processing.
  •  IntraCellular Diagnostic's EXA Test® offers you  tissue evaluations
     for the intracellular status of:

          MAGNESIUM         CALCIUM             POTASSIUM              
          PHOSPHORUS      SODIUM               CHLORIDE

  EXA Test® allows the Healthcare Provider to monitor and screen cellular mineral electrolyte balance objectively and repeatedly and follow a patient's metabolic physical status.

  EXA is the physician's noninvasive solution to the continuing problem of accurately measuring dynamic intracellular mineral electrolyte levels that impact a patient's quality of life.
