Q&A: Expert explains the reliability of Alzheimer’s blood tests

August 20, 2024 by Marla Paul, Northwestern University Credit: CC0 Public Domain Just as your primary care physician offers routine blood tests to gauge cholesterol or glucose levels, they might soon offer a blood test to diagnose Alzheimer’s disease. Two papers presented recently at the Alzheimer’s Association International Conference (AAIC 2024) add to growing evidence...

Blood tests outperform doctors at diagnosing Alzheimer’s

A commercially available blood test did a better job of detecting Alzheimer’s disease than primary care doctors or specialists using traditional tools, according to findings from a large study. Patients being evaluated for cognitive problems were tested with C2N Diagnostics’ PrecivityAD2 blood test, which looks for fragments of amyloid beta and tau proteins known to...

Accuracy of diagnostic blood tests for Alzheimer’s disease varies

July 30, 2024 by Washington University School of Medicine Determining performance of blood biomarker tests for amyloid pathology.Neurologists diagnose cognitive impairment with a clinical exam of memory and thinking skills. To determine whether Alzheimer’s disease is the cause of the cognitive impairment, evidence of the specific brain changes that characterize Alzheimer’s must be obtained, typically...

Less invasive for patients: Using blood tests to diagnose lung cancer

by Eindhoven University of Technology Credit: Pixabay/CC0 Public DomainCurrently, when lung cancer is suspected, a “morsel” of tissue is removed and examined under the microscope. This may change in the future. During her Ph.D. research, Sylvia Roovers-Genet examined proteins in the blood of people with, without, and with possible lung cancer, and thereby developed a method...

Researchers Improve Blood Tests’ Ability to Detect and Monitor Cancer

Tumors constantly shed DNA from dying cells, which briefly circulates in the patient’s bloodstream before it is quickly broken down. Many companies have created blood tests that can pick out this tumor DNA, potentially helping doctors diagnose or monitor cancer or choose a treatment. A blood test procedure.
