The Quality Improvement PrecivityAD2(TM) Clinician Survey and Clinical Utility Study (QUIP II) represents a large-scale initiative for the PrecivityAD2 blood test for use by neurologists, geriatricians, and geropsychiatrists (memory care specialists) who see patients aged 55 years and older with signs or symptoms of MCI or dementia.
C₂N Diagnostics, LLC is a CLIA-certified, CAP-accredited diagnostic testing laboratory based in St. Louis, MO. Its new test, the PrecivityAD2 blood test, measures plasma amyloid beta (Aβ) peptides 42 and 40 (Aβ42/40) Ratio and phosphorylated tau (p-tau) compared to non-phosphorylated tau (np-tau) at amino acid 217 of the tau peptide (p-tau217/np-tau217) ratio to determine whether a patient with signs or symptoms of cognitive impairment is likely to have brain amyloid plaques, a pathological hallmark of AD.
