The company recently announced a deal with personalized ctDNA testing firm Natera and will now follow that with the launch of its own MRD product this year.
Under the non-exclusive deal, Natera will use matched tumor and normal exome sequencing data from Personalis to validate the design of its Signatera ctDNA assays.
Last year, the company processed more than 1 million tests, most of them for its reproductive health business, but interest in Prospera and Signatera is growing.
The company believes its tests can already help oncologists better assess post-surgery risk, though prospective validation would be necessary for broad claims.
