CASCADE™
Three biomarkers. One honest read.
A plasma panel for Alzheimer-type pathology. CASCADE reports pTau217, the Aβ42/40 ratio, and a cross-platform composite against platform-specific cutoffs, then reads them for concordance under the 2024 Alzheimer's Association criteria. It calls borderline borderline, checks renal function before it trusts a value, and tells you exactly when to confirm with amyloid PET or CSF. It supports the diagnosis. It never makes it.
Lumipulse G · pTau217
0.395 pg/mL
POSITIVE ≥ 0.325
The single most accurate AD blood biomarker. Rises as tau tangles form.
Sysmex HISCL · Aβ42/40
0.092
BORDERLINE 0.090-0.102
Amyloid ratio, lower is abnormal. eGFR-independent. AUC 0.94.
Composite · exploratory
0.018
NEGATIVE ≤ 0.022
pTau217/Aβ42 concordance. Cross-platform, labelled exploratory.
Isolated · 1 of 3
One positive. Repeat or confirm with CSF / amyloid PET.
AT1 classification · 2024 AA
A+/- T1+
Partial positivity. One core biomarker positive.
APOE · ARIA risk
ε3/ε3 · low
No ε4 allele. Standard monitoring if treating.
eGFR 48 · mild, Aβ42/40 stays valid
Anti-amyloid support: not established
Platform-specific cutoffs
HCP sign-off required
