Emerging Trend
- Integration with Digital Microfluidics: The integration of digital microfluidic platforms has been gaining significant traction in chemiluminescence immunoassay workflows. These systems enable automated manipulation of samples and reagents on a single chip, reducing manual intervention and contamination risks. The miniaturized design supports faster turnaround times, enabling some platforms to deliver results in under 30 minutes compared to several hours required by conventional systems.
- Enhanced Sensitivity and Dynamic Range: Recent advancements in peroxidase-mediated CLIA reagents have improved assay precision and detection capabilities. Limits of detection have been reported as low as 0.1 pg/mL for specific biomarkers, with linear dynamic ranges extending across five orders of magnitude. This enhancement facilitates accurate measurement of both trace and high-concentration analytes, broadening the clinical applicability of CLIA technology.
- Point-of-Care Chemiluminescence Systems: Compact point-of-care CLIA devices are increasingly being adopted for near-patient diagnostics. The Accre 8 system performs a complete chemiluminescent assay in a single operational step with minimal calibration needs, delivering results in under 15 minutes. Validation involving 239 samples indicated an area under the ROC curve of 0.98 compared to LC-MS/MS systems, confirming its diagnostic reliability and utility for rapid clinical decision-making.
- Synergy with Molecular Diagnostics: CLIA systems are being increasingly integrated with molecular diagnostic platforms to enhance diagnostic accuracy. During the COVID-19 pandemic, chemiluminescent microparticle immunoassays were used alongside RT-PCR for confirmatory SARS-CoV-2 testing. This combined approach achieved sensitivity and specificity rates of 99% and 98%, respectively, reinforcing its value in strengthening clinical and public health surveillance.
