Moreover, they offer DecisionDx DiffDx-Melanoma and myPath Melanoma, both proprietary GEP tests employed to assist in the accurate diagnosis of ambiguous pigmented lesions. These specialized testing services are provided by Castle Biosciences to patients predominantly through their healthcare providers.
