Challenges in Sensitivity, Specificity, and Standardization
Prion diseases, such as Creutzfeldt-Jakob disease (CJD) and variant CJD, are characterized by long asymptomatic latency periods, during which infectious prions accumulate without overt clinical symptoms. Detecting prion diseases during this latency phase remains a formidable challenge, with sensitivity, specificity, and standardization of diagnostics at the forefront of current research and development efforts.
As of 2025, the most advanced diagnostic assays for prion diseases in latency are based on amplification techniques such as Real-Time Quaking-Induced Conversion (RT-QuIC) and Protein Misfolding Cyclic Amplification (PMCA). These methods have demonstrated high analytical sensitivity in research settings, capable of detecting minute quantities of misfolded prion protein (PrPSc) in cerebrospinal fluid (CSF), blood, and other tissues. However, translating this sensitivity into robust, reproducible clinical diagnostics is hampered by several factors.
First, the sensitivity of these assays can vary depending on the prion strain, sample type, and disease stage. For example, while RT-QuIC has shown >90% sensitivity for symptomatic sporadic CJD in CSF, its performance in pre-symptomatic or latent cases is less well established. Blood-based detection, which is critical for screening asymptomatic individuals, remains less sensitive and is still under active development by several organizations, including Bio-Rad Laboratories and Thermo Fisher Scientific, both of which are working on prion detection platforms for research and potential clinical use.
Specificity is another major concern. False positives can arise from cross-reactivity with other protein aggregates or from technical artifacts, especially in low-prevalence populations. This is particularly problematic for blood donor screening, where even a small false positive rate can have significant public health and economic consequences. Companies such as Abbott Laboratories have previously developed prion screening assays for blood, but these have not achieved widespread adoption due to specificity and regulatory challenges.
Standardization across laboratories and platforms is a further obstacle. There is currently no universally accepted reference material or protocol for prion detection in latent disease, making inter-laboratory comparisons difficult. Efforts are underway by international bodies such as the World Health Organization to develop standardized guidelines and reference reagents, but harmonization remains incomplete as of 2025.
Looking ahead, the next few years are expected to see incremental improvements in assay sensitivity and specificity, driven by advances in molecular amplification, antibody engineering, and digital detection technologies. However, the lack of standardized protocols and reference materials will likely continue to impede widespread clinical adoption of prion latency diagnostics. Collaboration between industry leaders, regulatory agencies, and public health organizations will be essential to overcome these challenges and enable reliable early detection of prion diseases.
