Video: Ratio calculation of Aβ1-42 and Aβ1-40 offers essential information about the buildup of amyloid pathology in a patient's brain

Early and accurate diagnosis of Alzheimer's disease helps patients manage their condition and lifestyle.

In vitro analysis of a few drops of cerebrospinal fluid - or CSF - gives the clinician immediate diagnostic insights, through the measurement of the four main biomarkers currently used to help diagnose Alzheimer's disease.

This 2 minute video explains why and how a ratio calculation of the two amyloid proteins, Aβ1-42 and Aβ1-40, offers particularly essential information about the buildup of amyloid pathology in a patient's brain.
