Castle Biosciences operates primarily in the field of molecular diagnostics, with a focus on dermatologic cancers and other diseases. The company’s core business segments include:

Dermatologic Cancer Diagnostics

  1. DecisionDx®-Melanoma: This is Castle Biosciences’ flagship product, a gene expression profile (GEP) test designed to predict the risk of metastasis in patients diagnosed with cutaneous melanoma. It provides critical information to guide treatment and surveillance strategies.

  2. DecisionDx®-SCC: A GEP test for patients with cutaneous squamous cell carcinoma (SCC), helping to identify those at high risk of metastasis and recurrence.

  3. DecisionDx®-UM: This test is designed for patients with uveal melanoma, a rare eye cancer, to predict metastatic risk and guide follow-up care.

Non-Dermatologic Diagnostics

  1. TissueCypher® Barrett’s Esophagus Test: This test evaluates the risk of progression to esophageal cancer in patients with Barrett’s esophagus, aiding in personalized treatment planning.

  2. IDgenetix®: A pharmacogenomic test that helps guide medication selection for patients with mental health conditions, such as depression and anxiety, based on their genetic profile.

  3. DecisionDx®-DiffDx-Melanoma: A diagnostic tool that helps differentiate between benign and malignant skin lesions, reducing diagnostic uncertainty.
