Determining accurate costs for genomic sequencing technologies—a necessary prerequisite

Genome sequencing (GS) is increasingly being translated into clinical practice and is a technology characterized by a complex multi-step workflow. Funding decisions for GS would be aided by formal economic evaluation of GS platforms, but these analyses require detailed costing. This article addresses the importance of and challenges associated with costing GS using a GS microcosting project in autism spectrum disorder as an illustrative example.
