I have asked this test multiple times to my oncologist. She believes there's nothing to be learned through it in metastatic setting. At one point she said, she asked to a Natera rep and that the rep agreed with her. However, another oncologist said the Natera MRD test would be helpful. I am so confused.

"The Signatera™ Residual Disease Test is a custom-built blood test for people who have been diagnosed with breast cancer or other solid tumors. Signatera™ can detect molecular residual disease (MRD) in the form of circulating tumor DNA—small fragments of DNA released by cancer cells."
