flag Roche gains CE Mark for first blood test detecting ApoE4, a gene linked to higher late-onset Alzheimer’s risk, aiding earlier diagnosis and treatment planning.

flag Roche has received CE Mark approval for the Elecsys ApoE4 test, the first blood-based in-vitro diagnostic to identify carriers of the ApoE4 gene variant linked to increased risk of late-onset Alzheimer’s disease. flag The test uses a simple blood sample to quickly distinguish carriers from non-carriers, reducing the need for confirmatory genetic testing and supporting earlier diagnosis. flag It aids in guiding treatment decisions, particularly for disease-modifying therapies that carry higher risks of ARIA in carriers. flag Validated in a study of 607 participants, the test is compatible with existing Roche diagnostic instruments and complements other blood-based biomarkers like pTau181. flag It is intended for adults with cognitive impairment and aligns with current clinical guidelines.
