Diagnostics lab demand is now big enough to pull measurable shares of both healthcare budgets and industry revenue chains, from clinical laboratory services to genomics and imaging workflows. Globally, health spending reached 4.0% of GDP in 2022, while diagnostic laboratory markets total hundreds of billions across services and adjacent testing categories. As labs increasingly automate accessioning, adopt reflex and remote sign out, and expand AMR and NGS testing, the numbers also reveal how utilization, compliance, and technology adoption vary dramatically by country and lab type.
