Stringent Multi-Region Regulatory Approval Timelines

The FDA’s laboratory-developed test rule imposes up to USD 3.56 billion in new compliance costs, stretching smaller innovators’ budgets and delaying product launches^{[2]U.S. Food and Drug Administration, “Laboratory Developed Tests: Regulatory Impact Analysis Final Rule,” fda.gov}. Europe’s IVDR extension buys time, yet manufacturers must still upgrade quality systems and secure notified-body slots, a resource bottleneck that inflates timelines. Dual submissions across jurisdictions fragment strategies and divert R&D spend away from new assay exploration. The drag is acute for AI-based tools that lack historical precedents, complicating dossier preparation and reviewer training, thereby tempering the overall in vitro diagnostics market trajectory.

Reimbursement Uncertainty Across Emerging Test Classes

CMS altered Signatera’s rate three times in one year, underscoring volatility in molecular test payment benchmarks. Gap-fill methodologies rarely align with rapid cost declines seen in NGS, forcing labs to absorb margin squeezes while generating real-world evidence demanded by private insurers. Coding complexity, especially with tiered molecular pathology stacks, adds back-office burden that erodes operating leverage. Until pricing frameworks stabilize for AI-enhanced or multi-omics panels, investment hesitancy may mute high-risk innovation within the in vitro diagnostics market.

Segment Analysis

By Test Type: Molecular Diagnostics Accelerates Despite Immunodiagnostics Dominance

Immunodiagnostics captured 29.05% of in vitro diagnostics market share in 2024, anchored by protein assays indispensable to infectious disease and metabolic testing. Yet molecular diagnostics is forecast to grow 6.59% annually, lifting the segment’s in vitro diagnostics market size as next-generation sequencing, multiplex PCR, and isothermal amplification become mainstays of precision medicine. Roche’s temperature-triggered 12-pathogen PCR further compresses run-times, removing throughput constraints that once limited molecular adoption in decentralized settings. 

Cross-fertilization is rising: hybrid platforms detect nucleic acids and antigens in the same cartridge, blending molecular specificity with immunoassay ease. AI algorithms stitch gene-expression results with serological markers, refining prognostic accuracy in oncology and antimicrobial stewardship. Laboratories thus migrate workloads from legacy immunoassays to low-cost, high-plex nucleic-acid formats, sustaining molecular’s outperformance through 2030.
