Our clinical study program<\/h2>\n
\n

We are committed to the utmost scientific rigor and have enrolled over 300,000 participants in a clinical study program to demonstrate broad applicability of our multi-cancer early detection technologies. To support and validate our technology, we are partnering with leading community and academic medical centers around the world.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n\n

PATHFINDER Study <\/div>\n
A prospective, interventional, return-of-results, multi-center study to assess the implementation of an earlier version of the Galleri\u00ae multi-cancer early detection (MCED) test in a clinical setting. Later, blood samples were reanalyzed with the current version of Galleri. <\/div>\n
