Stool Samples

Bay Biosciences recognize the critical role that stool (feces) biospecimens now play in new frontiers of research-from gut microbiome profiling to infectious disease, metabolic studies, and biomarker development. Our human stool samples are collected under IRB-approved protocols, thoroughly characterized and paired with rich donor metadata, making them ideal for translational research, drug development and clinical studies.

Stool samples can be used in the context of autoimmune diseases by testing for inflammation markers like fecal calprotectin, which indicates gut inflammation and can suggest diseases like Crohn’s or ulcerative colitis.

Additionally, stool analysis also examines gut microbiota and metabolites, which research shows are linked to various autoimmune conditions like rheumatoid arthritis, multiple sclerosis, and lupus. Consequently, this can help identify potential biomarkers for diagnosis, understand the disease’s mechanisms, and evaluate treatment effectiveness.

Why Choose Our Stool Biospecimens

  • Clinical-grade human stool samples from both healthy donors and disease-state cohorts, across multiple indications (Autoimmune, gastro-intestinal, metabolic, infectious, oncology).
  • Comprehensive donor/clinical metadata including demographics, health history, treatment history and disease status.
  • Flexible formats: frozen aliquots, homogenized, lyophilized, or pre-extracted nucleic acids, customized to your research needs.
  • Ability to provide matched biospecimen sets (e.g., stool + blood, stool + tissue) to support multi-omics and integrative analysis.
