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...
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...
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...

Which blood tests do you really need? And how often should you get them done? By Laura Entis detail of hand in blue nitrile glove holding vile of bloodPhoto: ShutterstockSometimes it may feel like almost every visit to the doctor includes a dreaded blood draw. Blood tests can reveal a lot about the state of...

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...
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.

The researchers revealed that all assays could reliably detect so-called...
DAVID NIELD, 6 APRIL 2021 In terms of biological aging, the body seems to shift gears three times during our lifespans, research from 2019 suggests – with 34 years, 60 years, and 78 years being the key thresholds. In other words, there’s evidence that aging isn’t one long, continuous process that moves at the same speed throughout...
