SPEAR UltraDetect™ unparalleled immunoassay precision: GFAP and NF-L

This application note highlights the exceptional sensitivity and precision of the SPEAR UltraDetect platform, demonstrated through two SPEAR UltraDetect™ assays targeting key neurological bio-markers: Glial Fibrillary Acidic Protein (GFAP) and Neurofilament-Light (NF-L). These assays deliver ultra-sensitivity with high precision, enabling reproducible detection of subtle, clinically meaningful changes—often missed by other ultra-sensitive platforms due to high variability. With remarkably low coefficients of variation (CVs) even at the lowest concentrations, SPEAR sets a new benchmark in analytical performance, making it a powerful tool for early detection and longitudinal study of neurological disease.
