PrecivityAD2's accuracy numbers are strong, but its borderline scores leave real diagnostic gaps that patients should ask about directly.

A blood test now helps evaluate Alzheimer's starting at age 40, but it works only alongside, not instead of, a full clinical workup.

A blood test can now flag amyloid in adults as young as 40, but for MCI it answers one question and leaves the progression question open.

A second FDA-approved tau tracer means an MCI workup can involve two different scans — knowing which one, and what it can answer, matters.

Why a positive Alzheimer's blood test and a negative Tauklarify scan in the same MCI patient aren't a contradiction.

Tauklarify's own trial data show a negative tau scan rules out tangles far more reliably than a positive scan confirms them.
