Quest Diagnostics (NYSE: DGX), a leader in diagnostic information services, today announced two new developments for its Quest AD-Detect® portfolio of blood-based biomarker tests for Alzheimer's disease, with the goal of broadening access to quality blood tests for evaluating symptomatic patients for Alzheimer's disease.

The U.S. Food and Drug Administration has cleared Roche (ROPC.S), opens new tab and partner Eli Lilly's (LLY.N), opens new tab blood test to help ​identify signs of Alzheimer's disease in people aged ‌55 and older with cognitive decline.

The U.S. Food and Drug Administration announced today that it has cleared C2N Diagnostics' PrecivityAD2 blood test for use in adults as young as 40 who are experiencing signs of cognitive impairment, making it the first FDA-cleared Alzheimer's blood test available to patients this young. The clearance builds on nearly 20 years of ADDF investment in C2N's science and reflects the growing momentum of blood-based diagnostics in bringing earlier, more accurate detection into mainstream care and moving the field toward a new era of precision medicine.

Beckman Coulter Diagnostics, a global leader in clinical diagnostics and a Danaher company, today announced it received CE Mark under IVDR for its Access p-Tau217 assay, a blood test designed to support clinical evaluation of amyloid pathology in patients with signs and symptoms of cognitive decline. The company also introduced its high-specificity Access BD-pTau217 Research Use Only (RUO) assay at the Alzheimer's Association International Conference (AAIC) 2026 in London.

TOBY, Inc., a biotechnology company developing non-invasive disease detection technologies, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Device Designation to the TOBY Test for Alzheimer's Disease. The designation recognizes the test's potential to aid in the diagnosis of Alzheimer's disease through a simple, non-invasive urine sample and address a major unmet need in accessible cognitive evaluation and diagnostic care.

Roche (SIX: RO, ROP; OTCQX: RHHBY) announced today that it has received CE Mark for Elecsys® pTau217, a blood test developed in collaboration with Eli Lilly and Company and designed to measure the phosphorylated Tau (pTau) 217 protein, an indicator of amyloid pathology and a hallmark of Alzheimer’s disease. The same cutoffs (high and low) of the blood test can be used across primary and secondary care settings, to rule in or rule out amyloid pathology in people presenting with symptoms or complaints of cognitive decline. The early detection of the amyloid pathology is critical for Alzheimer’s diagnosis and treatment, as it enables individuals, families, and caregivers to understand the cause of symptoms, access appropriate care, and actively contribute to the planning of next steps.

H.U. Group Holdings Inc. and its wholly owned subsidiary Fujirebio today announced that Fujirebio Europe N.V. has obtained a CE certificate of the Lumipulse G pTau 217 Plasma assay under the Regulation (EU) 2017/746 on in vitro diagnostic medical devices (IVDR). This CLEIA (chemiluminescent enzyme immunoassay) test allows for the quantitative measurement of Tau phosphorylated at threonine 217 (pTau 217) in human plasma (K2EDTA).

Lucent Diagnostics, a brand of Quanterix Corporation (NASDAQ: QTRX), today announced a collaboration with Tempus AI Inc. (NASDAQ: TEM), a technology company leading the adoption of AI to advance precision medicine, to broaden access to a novel blood-based biomarker panel designed to improve detection accuracy for Alzheimer’s disease. Through the agreement, Tempus AI will build a Tempus Next care gap program for Alzheimer’s disease blood-based biomarker testing, with the LucentAD® Complete multi-biomarker blood test becoming available for neurologists to order on the Tempus clinical ordering platform.
