Testing process

Castle’s Clinical Services team coordinates the collection and shipping of tissue blocks or slides directly from the pathology lab provided on the requisition form. The MyPath Melanoma test uses the same tissue from the original biopsy or excision procedure, avoiding additional procedures. This assay requires 10% tumor content.

Report results

The MyPath test result is reported as one of three categories: suggestive of benign, intermediate, or suggestive of malignant. A sample test report is available at the link below. Test results are available via our secure online portal within 3-5 business days from sample receipt.
