Haystack Oncology has developed a highly sensitive minimal-residual disease (MRD) testing technology, based on circulating tumor DNA (ctDNA), to aid in the early detection of residual or recurring cancer and better inform therapy decisions. Quest expects to incorporate this MRD technology into the development of new blood-based clinical lab services for solid tumor cancers available beginning in 2024.
