  1. Analytical and clinical validation of a high accuracy fully automated digital immunoassay for plasma phospho-Tau 217 for clinical use in detecting amyloid pathology

    ✓ Peer-reviewed alzhub usefulness score 48 out of 100. Frontiers in neurology 2025-07-09 Biomarkers

    The performance characteristics of the Simoa p-Tau 217 assay align with current accuracy recommendations for blood-based biomarker test performance for diagnostic use, making the test suitable for clinical use under the Clinical Laboratory Improvement Act (CLIA) as a diagnostic plasma test to aid in Alzheimer's diagnosis.

  2. Evaluation of plasma p-tau217 for detecting amyloid pathology in a heterogeneous community-based cohort

    ✓ Peer-reviewed alzhub usefulness score 60 out of 100. Alzheimer's & dementia : the journal of the Alzheimer's Association 2025-07-01 Biomarkers

    Plasma p-tau217 is an accurate indicator of amyloid pathology in a heterogeneous cohort and is superior to other plasma biomarkers assessed.
