Empowering people, informing care decisions.
At Castle, it all comes down to people. After all, disease doesn’t just happen — it happens to people. We believe that disease management and treatment decisions can be better informed through a person’s unique biology, which is revealed through the scientific rigor of our innovative tests. We are committed to empowering healthcare providers and patients with the goal of improved outcomes.
About UsClinical focus areas
Our broad portfolio of innovative tests focuses on answering critical clinical questions. From individualized risk of melanoma metastasis to customized medication profiles for mental health conditions, our tests are designed to deliver personalized information that better informs care decisions.

Prospective, multicenter analysis of RFS after SLN guidance from 31-GEP
This study is a prospective, multi-center study that assessed the effect of 31-GEP testing on SLNB performance rates in patients with T1–T2 tumors considering SLNB and to study long-term outcomes of patients with a Class 1A result (n=130). Of these low-risk patients, 63 had an SLNB, with a 3.2% SLN positivity rate (2/63). No Class 1A patients, regardless of SLN status, experienced a recurrence (2-year median follow-up). These results are consistent with previous studies that the 31-GEP can identify patients at low risk of SLN positivity and recurrence.

Metastasis-free survival prediction with the 40-gene expression profile test in patients with cutaneous squamous cell carcinoma risk stratified according to the National Comprehensive Cancer Network Guidelines
Despite definitive surgical treatment, a subset of cutaneous squamous cell carcinomas (cSCC) has an increased risk of regional/distant metastasis making it challenging to identify patients most at risk.1 The 40-gene expression profile (40-GEP) prognostic test improves risk stratification for patients with cSCC with known clinical or histologic risk factors, stratifying patients’ risk of metastasis as low (Class 1), higher (Class 2A), or highest (Class 2B) risk.
