The FDA has cleared the first-ever blood test for early Alzheimer's detection, which the agency says reduces the need for costly and invasive procedures.

In a Friday press release, the agency announced its approval of the first in-vitro diagnostic device, Lumipulse.

The new technology works by detecting You are not allowed to view links. Register or Login, a telltale sign of Alzheimer's.

While PET scans can pick up these plaques, they can be "costly and time-consuming" while exposing patients to radiation, according to the FDA.

In a You are not allowed to view links. Register or Login of 499 plasma samples from cognitively impaired adults, the Lumipulse test detected the presence of amyloid plaques in 91.7% of individuals.

The results indicate that the new blood test can "reliably predict the presence or absence of amyloid pathology associated with Alzheimer's disease at the time of the test in patients who are cognitively impaired," the FDA concluded.

"Knowing that 10% of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients," he said.

Center for Devices and Radiological Health Director Michelle Tarver, M.D., PhD, also commented in the press release that nearly seven million Americans are living with Alzheimer's.

"And this number is projected to rise to nearly 13 million," she said. 

"Today's clearance is an important step for Alzheimer's disease diagnosis, making it easier and potentially more accessible for U.S. patients earlier in the disease."
