The MyPath Melanoma GEP test will return a result of suggestive of benign, intermediate, or suggestive of malignant. The results are incorporated with all other clinical and pathological findings to inform a more definitive diagnosis and guide patient management.
Only a physician, physician assistant, or nurse practitioner can order MyPath Melanoma.
The accuracy of MyPath Melanoma has been assessed in multiple studies. The sensitivity and specificity of MyPath Melanoma have been reported as 90-97% and 89-86% respectively.
Only a physician, physician assistant, or nurse practitioner can order a TissueCypher test.

The TissueCypher test can be used after you have had an endoscopy with biopsies that have been confirmed by a pathologist to contain Barrett’s esophagus. Test results are reported directly to your healthcare provider approximately 18 to 20 business days from the date your sample is received by Castle Biosciences.
TissueCypher provides increased confidence that treatment decisions are tailored to each individual patient, leading to more personalized and precise care. The TissueCypher test is designed to:
- Be performed on existing biopsies taken during previous endoscopies; a repeat biopsy is NOT necessary.
- Identify patients at high risk of progression to esophageal cancer within five years of biopsy.
- Help detect existing high-risk disease or cancer that might have been missed by standard endoscopic surveillance.
- Identify patients who have a very low risk of progressing to cancer within five years of biopsy, providing additional information to help optimize surveillance strategy.
Additionally, the test has been shown to outperform predictions based on standard pathology alone.
The TissueCypher Barrett’s Esophagus test is the first test of its kind that predicts your risk for developing esophageal cancer if you have Barrett’s esophagus. It is intended for people with Barrett’s esophagus who have had an endoscopy procedure with biopsies. The test analyzes the biopsies taken during your endoscopy to produce a risk score that ranges from 0-10, with 0 being the lowest risk and 10 being the highest risk for developing more serious esophageal disease or cancer. Importantly, the test provides personalized information that can predict your chances for developing cancer.
Barrett's esophagus is a condition in which healthy cells in the esophagus turn into unhealthy cells. The esophagus is the tube that carries food from the mouth to the stomach. When acid from the stomach comes up into the esophagus (called Gastroesophageal Reflux Disease, or GERD), it can damage the cells that line the esophagus. In some people, Barrett's esophagus can become more serious and develop into cancer. While very serious, esophageal cancer can be prevented if the unhealthy cells found in high-risk Barrett's esophagus patients are treated before they turn into cancer.
This type of testing is an emerging, fast-growing field, so your doctor may not be aware of all of the tests that are now available to guide disease management decisions. If your doctor is interested in more information beyond our test descriptions on this website, please refer them to Castle Biosciences’ customer service (at 412-920-3050 or email).
