Aug 24 (Reuters) – The U.S. Food and Drug Administration has cleared Roche and partner Eli Lilly’s blood test to help identify signs ​of Alzheimer’s disease in people aged ‌55 and older with cognitive decline.

The test, Elecsys pTau217, is a biomarker blood test that can help doctors identify patients who are likely or unlikely to have Alzheimer’s-related brain ‌changes, ​Roche said on Monday.

The FDA ⁠clearance follows European ⁠approval for the test in May.

The test can be run on more than 4,500 Roche laboratory analyzers already installed across the United States, which ​the company said could help broaden access.

Separately, Labcorp and Quest Diagnostics said that they plan ⁠to offer the test through ⁠their laboratory networks, potentially expanding availability ​across the United States.

Roche did not disclose the test’s ​price.

Current methods to detect amyloid, a protein ‌linked to the disease, typically rely on positron emission tomography or PET scans or cerebrospinal fluid testing, which can be expensive, invasive and less ⁠widely available.

The FDA clearance comes as drugmakers and diagnostic companies race to develop simpler tests for Alzheimer’s disease amid ⁠growing demand ‌for earlier diagnosis and treatment.

Fujirebio’s Lumipulse ⁠became the first blood test cleared ​by ‌the FDA to aid in the ​assessment of ⁠Alzheimer’s disease in 2025.

Elecsys pTau217 is not intended to be used as a standalone diagnostic test and results should be interpreted alongside other clinical information, Roche said.
