Key Exhibition Areas and Technologies
The following are representative technologies relevant to clinical laboratory products and the specialist fields of JCLS. They do not constitute a confirmed list of exhibits or scientific sessions for 2027.
- Clinical Chemistry and Immunoassays: Biochemistry analyzers, immunoassay instruments, analytical reagents and biomarker assays.
- Hematology Testing: Hematology analyzers, coagulation testing, blood cell analysis and flow cytometry.
- Genetic Testing and Molecular Diagnostics: Nucleic acid extraction, PCR, next-generation sequencing (NGS) and genetic testing reagents.
- Microbiology and Infectious Disease Diagnostics: Microbial identification, antimicrobial susceptibility testing, rapid diagnostic tests and cultivation technologies.
- POCT and Physiological Function Testing: Point-of-care testing, rapid measurement instruments and physiological testing technologies.
- Laboratory Automation: Specimen transportation, automated liquid handling, sample preparation, analyzer integration and laboratory workflow optimization.
- Quality Control and Healthcare Informatics: Quality control materials, measurement standardization, laboratory information systems (LIS) and data utilization.
Pharma Nexus highlights: Particular attention can be given to technologies that automate processes from sample preparation and measurement to results management, accelerate testing, improve reproducibility and reduce manual workloads. The translation of research technologies in genetic analysis and proteomics into clinical laboratory applications is another important area. Research-use products and clinical diagnostic products differ in intended use and regulatory status, which should be considered when evaluating product information.
