Key facts

Cytolethal distending toxin B+Vinculin Ab [Interpretation] in Serum Qualitative by Immunoassay
Cytolethal distending toxin B+Vinculin Ab
Cytolethal distending toxin B (CdtB) and vinculin antibodies are useful as biomarkers for irritable bowel syndrome with diarrhea (D-IBS) in humans. Studies suggest that elevated levels of vinculin antibodies are more commonly found in patients with D-IBS than those with other forms of inflammatory bowel disease (IBD) and may help distinguish the two. [PMID25970536] This term was created for, but is not limited in use to, the Quest Diagnostics' IBSDetex assay.
