The Lumipulse G GFAP assay shows potential in differentiating Alzheimer's from non-Alzheimer's cases, particularly with tau-related pathology.
In a study of 30 CSF samples, the assay achieved an area under the curve (AUC) of 0.86 for distinguishing cases based on pTau181 positivity.
Using the automated LUMIPULSE G system, researchers measured GFAP alongside Aβ40, Aβ42, and pTau181, highlighting its diagnostic capabilities.
Findings suggest GFAP could serve as a complementary biomarker, but further research is needed for its role in other neurological disorders.
