Leveraging data for enhanced efficacy and precision

With access to over 60 billion lab test results, an expanding range of more than 3,500 assays, and a database encompassing approximately half of the US population, we are poised to provide you with the insights necessary for data-informed decision-making at pivotal development junctures.

  • Discerning gaps in patient care, understanding disease prevalence, assessing treatment trends, and anticipating potential outcomes to shape a more effective program framework
  • Collating pertinent, high-grade data aligned with your neurology product's target and potential indications, enhancing your trial's likelihood of success

  • Employing up-to-date clinical and molecular data to adeptly match patients to biomarker-specific clinical studies.
  • Gaining a more nuanced grasp of site efficacy, courtesy of investigator site data that spans a significant portion of global clinical trials.

  • Undertaking in-depth analysis of cohorts delineated by therapeutic indication or explorative endpoint evaluations, such as HCP, ICD 10, diagnosis, and biomarker status.
  • Facilitating faster testing through improved pipeline transparency, focused outreach, and predictive forecasting.

Enhancing patient access to biomarker-focused therapies through knowledge & outreach

Tap into Quest's vast commercialization know-how, bolstered by our versatile team. We present a rich portfolio alongside tailored partnership solutions:

Ensure the diagnostic test is available operationally to complement your therapeutic upon its approval, all facilitated by our wide-range of laboratory networks.

Speed up testing processes with improved pipeline transparency, targeted outreach, and forecasting, all made possible by Quest Diagnostics bioinformatics expertise.

Boost awareness and ease the ordering process for companion or complementary diagnostic tests. This is achieved through both past and future collaborations between healthcare providers and our medical affairs division at Quest.

Enhance patient reach to your therapeutic solution by tailoring strategies to address diagnostic use hurdles, healthcare provider training, and concerns over testing coverage.

Through the Pack Health proven white-label solution, strive for better adherence, an elevated patient experience, and cost-effective care management.

Biomarker discovery & confirmation

Rely on our scientific expertise and extensive global lab testing capabilities. Our aim is to complement your translational team and assist in crafting a holistic neurology biomarker approach. Together, we'll pinpoint and cultivate suitable biomarkers to refine your clinical development plans.

QUEST AD-Detect™ blood-based Alzheimer’s disease (AD) risk assessment portfolio:

Assess AD risk with a simple, accessible, and affordable blood test.

QUEST AD-Detect™ Amyloid Beta 42/40 Ratio, Plasma

This test is used to assist in the differential diagnosis of AD and establishes a baseline and monitors over time. Our high-precision assay, using a simple blood sample, is the same type of assay shown to be as effective as traditional standard of care methods, such as cerebrospinal fluid (CSF) testing and amyloid positron emission tomography (PET) scans.

QUEST AD-Detect™ Apolipoprotein (ApoE) Isoform

Apolipoprotein E (ApoE), the primary brain apolipoprotein, is a biomarker for AD that can be found in the blood or CSF. The presence of an E4 allele is associated with both increased disease risk and decreased average age of onset compared with E2 or E3 alleles.


Can be ordered alongside other tests in the QUEST AD-Detect portfolio, such as QUEST AD-Detect Amyloid Beta 42/40, for a more robust risk assessment.
