The LucentAD test measures an isoform of phosphorylated tau protein in blood which is correlated to the presence of amyloid pathology in the brain, a hallmark of Alzheimer’s disease. The test can help your healthcare provider determine the likelihood of amyloid pathology.
The LucentAD test measures phosphorylated tau protein, which has been extensively studied in Alzheimer’s disease and correlated to the presence of amyloid pathology in the brain through comparison with gold standard techniques such as amyloid positron emission tomography (PET) imaging.
If you are experiencing memory issues, you should talk to your healthcare provider and ask if the LucentAD test is right for you.
Individuals with a family history of Alzheimer’s disease may be at higher risk. You should consult your healthcare provider about whether you should get tested.
Getting the LucentAD Test
A prescription is required to get a LucentAD test. Please contact your healthcare provider to discuss whether the LucentAD test is appropriate for you.
A healthcare worker will collect a small amount of blood from a vein in your forearm using a standard collection vial. Your blood test sample will be sent to Quanterix Corporation (Quanterix, provider of the LucentAD test) for laboratory analysis.
The LucentAD test is new and is not currently covered by private insurance payers, Medicare or Medicaid. Patients are responsible for paying for the test out-of-pocket. Quanterix is currently working to establish reimbursement for the LucentAD test.
You will receive a bill from your provider.
Lucent Diagnostics will send a lab report with the test results to your healthcare provider within ten business days of receipt of the blood sample. You can request a copy of your lab report from your healthcare provider.
The LucentAD test lab report includes your pTau level which will be referenced against the LucentAD clinical cutoff for likelihood of Alzheimer’s pathology test. Your healthcare provider will discuss your report with you, answer any questions, and discuss next steps of your care.
Alzheimer’s disease is the most common cause of dementia, a general term for memory loss and other cognitive issues serious enough to interfere with daily life. Alzheimer’s disease accounts for 60-80% of dementia cases. For more information and resources on Alzheimer’s disease, please visit Alzheimer’s Association – What is Alzheimer’s.
