Elecsys® pTau-217 is the first and only FDA-cleared single-biomarker blood test to both rule in and rule out amyloid pathology across specialty and primary care settings
Measures phosphorylated Tau 217 (pTau-217), an indicator of amyloid pathology and a hallmark of Alzheimer's disease
Intended for individuals 55 and older with signs, symptoms or complaints of cognitive decline
BURLINGTON, N.C.

/PRNewswire/ --
Labcorp
(NYSE: LH), a global leader of innovative and comprehensive laboratory services, announced today it will offer the Elecsys® pTau-217 test following clearance by the
U.S. Food and Drug Administration
(
FDA
). Developed by
Roche Diagnostics
, the blood test aids in identifying amyloid pathology associated with Alzheimer's disease in individuals 55 and older with signs, symptoms or complaints of cognitive decline. Elecsys® pTau-217 is the first and only FDA-cleared single-biomarker blood test to both rule in and rule out amyloid pathology across specialty and primary care settings
For many individuals experiencing cognitive decline, evaluation for Alzheimer's disease often involves multiple tests, care settings and healthcare providers. As blood-based biomarkers for neurological conditions continue to advance, pTau-217 has emerged as a leading biomarker to help clinicians rule in or rule out amyloid pathology in people presenting with symptoms or concerns of cognitive decline. While several pTau-217 assays are commercially available, standardization across care settings remains an important consideration for clinicians. The Elecsys® pTau-217 test provides a single, standardized assay with the same clinically validated cutoffs across primary and specialty care settings, supporting a consistent approach to patient assessment.
"The best advances in Alzheimer's disease testing should make the diagnostic process simpler, more accessible and more consistent for both patients and clinicians," said Dr.
Brian Caveney
, chief medical and scientific officer at
Labcorp
. "For individuals and families seeking answers about cognitive changes, the path to evaluation can be long and uncertain. By making the Elecsys® pTau-217 test available nationwide,
Labcorp
is expanding access to innovative blood-based testing and helping clinicians provide more timely assessments and informed next steps for patients."
Key Features of the Elecsys® pTau-217 Test
Uses the same clinical cutoffs across primary and specialty care settings, providing a standardized approach to patient assessment.
Provides positive, intermediate and negative result categories to support assessment of the likelihood of amyloid pathology.
Offers a convenient, minimally invasive blood-based testing option with performance comparable to cerebrospinal fluid (CSF) testing and positron emission tomography (PET) imaging.
Once ordered by a clinician, patients can have their blood drawn in a physician's office or at one of
Labcorp's
more than 2,200 patient service centers nationwide.
Results are interpreted alongside clinical information and other relevant findings as part of a comprehensive evaluation.
