Mercy BioAnalytics, Inc. is on a mission to relieve suffering and save lives through the early detection of cancer. Early-stage cancer is difficult to detect, but when found, is more often amenable to curative therapy. The patented Mercy Halo™ liquid biopsy platform utilizes biomarker co-localization to interrogate highly abundant blood-based extracellular vesicles that carry unique cancer signatures from their parent cells. The Mercy Halo™ platform is designed to detect stage I cancer, when it is most treatable, and enhance the quality of life for cancer patients and their families. Mercy’s initial focus is the early detection of ovarian and lung cancers. Ovarian cancer, the most lethal gynecological cancer, typically goes undetected until it is too late to cure. Lung cancer, the number-one cancer killer, takes more lives than breast, prostate, and colorectal cancers combined. For additional information, please visit
