Methods and apparatus for electro-meridian diagnostics

A current sensor may take measurements of electrical currents that flow between two limbs of a patient through at least a portion of the patient's torso. The current measurements may be taken during a single diagnostic session while the patient holds a ground electrode in a hand of one limb and a probe electrode is sequentially placed at different locations on the distal portions of other limbs. Each of the measurement locations may be an acupuncture point. An electrical current state for the diagnostic session may be calculated. This state may consist of current ranges for one or more electrical currents that are measured during the session. A lookup table may be employed to determine one or more medical conditions that are indicated by the current state. Alternatively, a trained machine learning model may predict, based on the measured currents, one or more medical conditions.
