Electrical impedance spectroscopy (EIS) is a noninvasive method that aims to help diagnose skin cancer. The EIS device consists of a handheld probe with a disposable electrode that is applied directly on the skin and uses electrical impendence differences to differentiate between normal and abnormal skin lesions. The EIS algorithm is best used on lesions that are deemed clinically or dermoscopically suspicious and has a high sensitivity in detecting malignant melanoma. The greatest usefulness of EIS is achieved in conjunction with a physician who has experience with this modality and excellent training in the clinical detection of suspicious lesions.
