Products
Plasma assay for brain amyloid status (LC‑MS/MS laboratory-developed test)
A targeted LC‑MS/MS plasma assay measuring amyloid-beta peptide ratios and related proteotype features to estimate presence of brain amyloid pathology and support clinical evaluation of cognitive impairment.
Plasma apolipoprotein E (ApoE) proteotype assay
Proteomic measurement to infer apolipoprotein E proteotype/allele status from plasma to inform clinical management when APOE allele information is relevant.
Plasma phospho‑tau (pTau217) quantitative assay
Targeted LC‑MS/MS measurement of phosphorylated tau peptide concentrations in plasma for use in multianalyte algorithms and longitudinal monitoring of tau-related pathology.
