Noninvasive, microbiome-based diagnosis of inflammatory bowel disease (Nature)

Researchers have developed a promising microbiome-based diagnostic test for inflammatory bowel disease (IBD), leveraging metagenomic data from nearly 6,000 fecal samples across various populations. By identifying specific bacterial species associated with ulcerative colitis and Crohn’s disease, the diagnostic models achieved high accuracy, outperforming the current standard, fecal calprotectin. This test, which targets IBD-related bacteria, offers a non-invasive and potentially more reliable tool for early diagnosis. Could this breakthrough reshape how we diagnose and manage IBD?
