First Leukemia Diagnostic Test Based on DNA Sequencing Detects up To 51 Gene Mutations
Until 2022 the only leukemia tests done could detect two gene mutations. Now, a new leukemia diagnostic test is capable of detecting 51 gene mutations, marking a significant technological and medical advancement. More...02 Jan 2023
Biomarker Test Detects Alzheimer’s Neurodegeneration in Blood
Scientists have applied their knowledge of molecular biology and biochemistry of tau proteins in different tissues, such as the brain, to develop a technique to selectively detect “brain-derived tau,” or BD-tau, a novel marker of Alzheimer’s disease neurodegeneration, while avoiding free-floating “big tau” proteins produced by cells outside the brain.

Tuberculosis Pathogen Dynamics Detected With Nanopore Sequencing
Mycobacterium tuberculosis whole-genome sequencing (WGS) has been widely used for genotypic drug susceptibility testing (DST) and outbreak investigation. For both applications, Illumina technology is used by most public health laboratories. More...26 Dec 2022
Real-Time PCR-Based Serological Diagnosis of Human Granulocytic Anaplasmosis
Human granulocytic anaplasmosis (HGA) is a tick-borne infection caused by the intracellular bacterium Anaplasma phagocytophilum, an emerging pathogen. HGA can manifest as a subclinical infection; however, most symptomatic persons have fever, myalgia, and headache associated with thrombocytopenia, leukopenia, and elevated transaminase levels. More...26 Dec 2022
Ultrafast, Ultra-Sensitive Protein Detection Method Enables Ultra-Early Disease Diagnosis
Methods to analyze trace amounts of proteins based on antigen–antibody reaction enable diagnosis at an early stage of many diseases, including cancer, dementia, and microbial infections. Now, a team of scientists has discovered a new principle underlying light-induced acceleration of antigen–antibody reaction, allowing for simple, ultrafast, and highly sensitive detection of proteins.
