Amyloid βeta Confirmed™ Program

Laboratory testing sponsored by Biogen and offered through Mayo Clinic Laboratories

About the program

Mayo Clinic Laboratories is proud to offer Alzheimer's disease biomarker testing as part of the Biogen-sponsored Amyloid βeta Confirmed™ Program. Participating providers will gain access to Mayo Clinic Laboratories' advanced cerebrospinal fluid (CSF) evaluation at no cost* to help broaden access and improve care planning for patients being evaluated for mild cognitive impairment (MCI) or mild dementia clinical stages of Alzheimer's disease.

To learn more about the program, please visit the program site.


*The Amyloid βeta Confirmed™ program will cover the cost of Aβ CSF laboratory testing only and does not cover the cost of the lumbar puncture procedure or any other related costs. The lumbar puncture procedure may be covered by the patient’s insurance provider. Because Biogen is paying for the cost of the test, health care providers must not seek reimbursement for the sponsored CSF test from the patient or any third-party payer, including but not limited to federal health care programs. This program is not intended to be an obligation or inducement to recommend, purchase, prescribe, promote, administer, use or support any Biogen product or to order medically unnecessary testing from Mayo Clinic Laboratories. Health care providers are responsible for ordering testing in accordance with their professional medical judgment and applicable laws. The program is subject to termination or modification at any time.

Answers to guide more informed decisions

When it comes to Alzheimer’s disease, early detection is important for disease management. We have developed a validated evaluation for Alzheimer’s disease, which uses CSF biomarkers to achieve a high concordance with amyloid positron emission tomography (PET) scan. Our test method reduces pre-analytical variability for diagnostic accuracy with each result. This new test also delivers fast results, providing timely answers to health care professionals and their patients.

Specimen collection

We require a specific polypropylene low-binding tube that has been shown to provide more accurate results for patients. 

Patient preparation: For 12 hours before specimen collection, do not take multivitamins or dietary supplements containing biotin (vitamin B7), which is commonly found in hair, skin, and nail supplements and multivitamins. 

Specimen volume: 2 mL 

 Collection instructions: 

  • Perform lumbar puncture and discard the first 1 to 2 mL of CSF. 
  • Collect 2 mL of CSF directly into CSF AD Biomarker Tube. Do not aliquot. Analysis needs to be performed using collection tube. 
    • Protocol recommends using drip method vs. syringe pull method.
  • Refrigerated (preferred), but frozen and ambient are also accepted when following specimen stability requirements.
