Roche receives CE Mark for minimally invasive blood test to help rule out Alzheimer's disease

Barriers to early and accurate diagnosis of Alzheimer’s disease exist across the world. Up to 75% of people living with symptoms are not diagnosed, and those who have received a diagnosis waited nearly three years on average after symptom onset. The identification of amyloid pathology is critical for Alzheimer’s diagnosis and treatment. Current methods to confirm amyloid pathology - including positron emission tomography (PET) and cerebrospinal fluid (CSF) assessment - can be expensive, difficult to access and invasive. With a negative Elecsys pTau181 blood test, people can avoid further unnecessary investigations for Alzheimer’s using CSF or PET and can identify the care pathway that is right for them.

Clinical study results support that the test can be implemented effectively across care settings, including primary care, where most patients first seek help for cognitive concerns. Those with positive results are then able to undergo further testing, supporting earlier identification of Alzheimer’s pathology.
