Tempus xF Monitor assay

Tempus xF Monitor assay measures quantitative molecular changes in ctDNA tumor fraction by utilizing diverse genomic events, dynamically weighting somatic variant allele frequencies and copy number variants, while using germline information to inform these estimates. The algorithm that powers xF Monitor – xF ctDNA tumor fraction – utilizes multiple single input models and weights their importance based on failure modes observed in Tempus’ multimodal database.
