Faster detection of pancreatic cancer
News Release 9-Aug-2024 Glycopeptide probes detect tumor-associated antibodies in blood samples Peer-Reviewed PublicationWiley Pancreatic cancer is one of the most lethal forms of cancer, primarily because it is usually diagnosed very late. Current markers are too insensitive and unspecific for early detection screenings. In the journal Angewandte Chemie, a research team has now introduced a...
New evidence casts doubt on a much-hyped blood test for early cancer detection
August 7, 2024 by British Medical Journal Credit: Karolina Grabowska from PexelsNew evidence published by The BMJ today casts doubt on a much-hyped blood test for the NHS that promises to detect more than 50 types of cancer. The test, called Galleri, has been hailed as a “ground-breaking and potentially life-saving advance” by its maker,...
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
