Castle Biosciences develops and commercializes diagnostic and prognostic tests for cancers that provide actionable, tumor-specific information for improved treatment decisions and patient outcomes.
Our first test for uveal melanoma, a rare and deadly eye cancer, is used to identify those at high risk for metastasis. With demonstrated improved accuracy over existing staging and prognostic tools, the test has become the standard of care for uveal melanoma and has successfully secured reimbursement. We are using its innovation as a model for our growing lineup of practice-changing tests, including our newer cutaneous (skin) melanoma prognostic assay. Our full lineup includes tests for esophageal cancer, mesothelioma, glioblastoma multiforme, and assays in development for rectal cancer.
Castle Biosciences’ tests are performed in a CLIA-certified, CAP-accredited clinical laboratory.
