I'm sorry but I don't have the answer to your question. I am in the process of have blood maker testing done through Guardant. it's called the 360 test. This test will capture the DNA shed from tumors in the blood. It will provide a comprehensive overview of the genomics in both the primary tumor and metastatic sites. The test is used to detect gene mutations in circulating cell free DNA {cfDNA}. The hope is they will be able to identify the best form of treatments going forward. Hope this information may help. I certainly wish you all the best in your fight.
