People suspected of having Alzheimer’s disease will in future be able to have another option for receiving a confirmed diagnosis following the approval of a new blood test by the US Food and Drug Administration. The approval, announced on 16 May, is for an in vitro diagnostic device, the first of its kind. It is called the Lumipulse G pTau217/beta-amyloid 1-42 plasma ratio. The developer is Fujirebio Diagnostics Ltd of Japan.
