The article reports that a new blood test, called the EasyM protocol, has been certified by the US Food and Drug Administration (FDA) for use in detecting multiple myeloma relapse. The test works by detecting small amounts of circulating tumor DNA (ctDNA) in the blood, which can indicate the presence of residual disease. The EasyM protocol is reportedly more sensitive than existing tests for detecting ctDNA, and can provide results in just a few hours. The article notes that the test has the potential to improve patient outcomes by allowing for earlier detection of relapse and more personalized treatment options.
