Proteomics: from basic research to diagnostic application. A review of requirements & needs

Area of Science:

• Clinical Proteomics
• In Vitro Diagnostics (IVDs)
• Biomarker Discovery

Background:

• Proteomics research holds promise for identifying novel biomarkers for clinical applications.
• Translating proteomics technologies like protein arrays and SELDI-TOF MS into IVD instruments presents opportunities and challenges.
• In vitro diagnostics are essential for healthcare, guiding decisions on prevention, diagnosis, and treatment.

Purpose of the Study:

• To outline the essential requirements and needs for in vitro diagnostics.
• To discuss the implications of these IVD requirements for clinical proteomics research.
• To facilitate the translation of proteomics findings into routine clinical practice.

Main Methods:

• Review and analysis of in vitro diagnostic requirements and needs.
• Consideration of technological aspects, including protein arrays and SELDI-TOF MS.
• Evaluation of performance characteristics, accuracy, sensitivity, and specificity for diagnostic tests.

Main Results:

• In vitro diagnostics must provide reliable information for clinical decision-making, supported by cost-benefit analyses.
• Key IVD requirements include definitive diagnosis, stringent analyte performance (precision, trueness), and adequate diagnostic accuracy (sensitivity, specificity).
• Addressing IVD needs early can accelerate the transition of research findings into clinical practice.

Conclusions:

• Fulfilling essential IVD requirements is mandatory in the regulated diagnostic environment.
• Understanding and addressing IVD needs early supports the acceptance and implementation of new diagnostic tools.
• Applied research in clinical proteomics should align with IVD requirements to ensure clinical utility and impact.
