Simoa Revolutionizes Pediatric Neurology Diagnostics

Quanterix's announcement that its Simoa technology supported a significant international study to define the serum neurofilament light chain (sNFL) reference ranges for assessing neurological disease activity in children and adolescents marks a major advancement in the field of neurological diagnostics.

The study, conducted in collaboration with researchers from the University Hospital Basel and the University of Basel, utilized Simoa's highly sensitive detection abilities to reliably measure sNfL protein levels. This enabled a vast international study encompassing a wide age range from neonatal to adolescence. The Blood NfL is a promising biomarker reflecting neuroaxonal health, but its clinical application has been limited due to the lack of established reference ranges for the younger population. Addressing this constraint, the study offers a comprehensive examination of 2,667 samples and successfully establishes a robust reference database that can aid clinicians in interpreting sNfL levels in individual children and adolescents.

The European Medicines Agency's recent call to introduce age-adjusted reference values for NfL accentuates the importance of this study, as it paves the way for blood NfL's clinical application in children. This significant achievement could transform early neurological disorder detection in children and have significant socioeconomic implications.

Moreover, the study emphasizes the unique advantages of Quanterix's digital Simoa NfL assay, including precise measurement from small sample volumes and applicability across various sample types. This highlights the innovative capabilities of Simoa technology, not only in research but also in real-world clinical applications.

With the expansion of NfL to Quanterix's clinical laboratory improvement amendments validated lab-developed tests, the company is aligning its groundbreaking Simoa technology with the growing need for effective diagnostics in neurological diseases across all age groups. The potential of blood NfL to serve as a suitable biomarker for conditions like spinal muscular atrophy during early childhood, coupled with its combination with other biomarkers, adds to the clinical promise of Quanterix's Simoa assays.

Simoa Technology Faces Various Business Risks

While the ability to detect and quantify biomarkers at ultra-low levels is an innovative advantage, it might also introduce susceptibility to contamination or interference.
