“Today’s clearance is an important step for Alzheimer’s diagnosis, making it easier and potentially more accessible for US patients earlier in the disease,” stated Michelle Tarver of the FDA’s Middle for Units and Radiological Well being.
The check is allowed to be used in scientific settings for sufferers exhibiting indicators of cognitive decline, and outcomes should be interpreted alongside different scientific data.
