A new way to
guide patient care
Definitive answers to guide
When it comes to Alzheimer’s disease, early detection is essential to better care. While Alzheimer’s is challenging to treat, early diagnosis offers a number of advantages, including access to medication and therapies used to alleviate symptoms.
Mayo Clinic Laboratories has developed two innovative evaluations for Alzheimer's disease, which use cerebrospinal fluid (CSF) biomarkers to achieve a high concordance with amyloid positron emission tomography (PET) scan. The methodology on both tests are optimized to reduce pre-analytical variability and ensure diagnostic accuracy with each result.
These clinically validated tests deliver fast results and provide new hope for correctly diagnosing and managing Alzheimer’s disease along with other dementias.

Clear results that guide treatment decisions
Fast, cost-effective answers when you need them most
Diagnosing Alzheimer’s disease is a challenge. We use the most up-to-date methodology: automated immunoassay with innovative instrumentation. Our results are based on ratios of p-tau and AB42 (ADEVL) and AB42 and AB40 (AMYR), which allows for greater than 90% diagnostic accuracy compared to standard assessments. We also use low-binding tubes, resulting in fewer false results for patients.
A diagnosis of Alzheimer’s disease can change a patient's life. Receiving a fast, definitive answer from a health care institution they trust can provide hope and a plan for their future. Whether it is the right treatment for symptom management, confirmation of diagnosis, or eligibility for clinical trials, we are here to provide the highest quality of care.
A differential diagnosis can change treatment and improve patient care. With our testing, patients receive the answers they need in as little as one day. They don’t have to wait weeks or months to be placed on the right treatment and start planning for their future.
A complementary solution to assist with diagnosis
Standard assessment of suspected Alzheimer's disease patients through clinical and cognitive assessment is 70%–80% accurate. By adding our Alzheimer's disease evaluations, physicians can increase diagnostic accuracy by 12%–22% to ensure they are providing the correct diagnosis and treatment for patients.

When to consider testing
A Test in Focus
Alicia Algeciras-Schimnich, Ph.D., gives an overview of this test. She discusses when this testing should be ordered, how this testing compares to previous testing approaches, and what clinical action can be taken due to the results of this testing.

Cerebrospinal fluid (CSF) has been used in research on Alzheimer’s disease for decades, but only recently have the platforms been developed to standardize measurements across laboratories.
We require a specific polypropylene low-binding tube. In clinical studies, this tube has been most effective in preventing Ab42 adsorption and can provide more accurate results for patients.
Our testing is validated and developed through the use of in-house clinical studies. We also reference publications and research in each of our reports to provide clinical evidence to our interpretations.
