Description
Helena Blasco-Forniés and eight co-authors wrote this 2025 conference study on two practical worries for Alzheimer's blood tests. Blood markers can flag the disease, but clinics need to know whether a recent meal or years in a freezer skew the readings. The team tested both questions in a Spanish research cohort.
Samples taken while fasting held less of two amyloid markers than fed samples, yet their ratio, the value doctors lean on, stayed steady. Three other markers showed no meal effect at all. After ten years in deep freeze, amyloid readings ran higher and two other markers ran lower, while the key tau marker held firm. The markers still spotted disease just as well in both meal states. The authors advise noting storage time when labs compare old samples.
