Quest Introduced First-To-Market Consumer-Initiated Blood Test for Alzheimer’s Disease Risk Assessment on Questhealth Website

On July 31, 2023, Quest Diagnostics, a leader in diagnostic information services, announced the introduction of the AD-Detect™ Test for Alzheimer’s Disease on – the first blood test available for consumer purchase that helps to assess the potential risk of developing Alzheimer’s disease based on a brain protein that contributes to the condition.

Quest introduced the novel innovation in the midst of a rapidly evolving landscape for Alzheimer’s disease treatment, which included new and emerging therapies, growing acceptance among medical professionals of blood tests to help with early Alzheimer’s disease detection, and growing recognition that non-pharmacological interventions can reduce Alzheimer’s disease risk.

In the AD-Detect screening test, levels of amyloid beta proteins are measured in plasma, the liquid portion of blood, from a single blood, draw in order to identify potential early warning signs of Alzheimer’s disease. In the brain, amyloid beta proteins are known to build up and form plaques, which are associated with the development of Alzheimer’s disease. Two amyloid beta peptides, A-42 and A-40, are measured by AD-Detect in plasma.

The consumer-initiated test makes use of the same expertise and technology as Quest’s clinical AD-Detect Amyloid Beta 42/40 Ratio test, a blood test that helps determine the risk of Alzheimer’s disease and is analytically validated. People can purchase AD-Detect through Quest’s consumer-initiated testing platform, giving them more control over the choice of when and how to assess their cognitive health. Along with guaranteeing that people have access to a continuum of care, the test program also provides clinical oversight for test ordering and results delivery through a network of independent doctors. Patients can discuss their results with a doctor to better understand what they might mean and to decide on a plan of action for ongoing care, including whether a follow-up visit with their general practitioner or a specialist might be necessary.

“We are seeing much attention on emerging therapies for Alzheimer’s disease, but with new treatment options will come the need to make screening and diagnosis more widely available. Blood tests like AD-Detect hold incredible potential to make Alzheimer’s disease risk assessment both accessible and convenient,” said Michael K. Racke, M.D., Medical Director of Neurology, at Quest Diagnostics. “We’re also seeing a push from consumers who have a desire to take more control of their health, including within more advanced areas like Alzheimer’s disease risk assessment.”

Even if they are not exhibiting symptoms, are 65 years of age or older, have experienced brain trauma, or have had a head injury, people who believe they are experiencing cognitive decline or whose loved ones may be able to detect mild cognitive impairment, such as memory loss, may benefit from taking the new Quest test. Blood tests like AD-Detect can help shed light on potential Alzheimer’s disease risk and assist people in facilitating necessary medical consultations.
