Biofluid Data type

What is a Biofluid?

A Biofluid (biological fluid) is any fluid found within the human body that can be collected and analyzed for research or diagnostic purposes.

Common Biofluids in CMMI Studies

• Blood: Plasma, serum, whole blood
• Urine: Urine samples for metabolite analysis
• Saliva: Oral fluid collection
• Feces: Gut microbiome and metabolite analysis

Importance in Omics Studies

Different biofluids provide different information:
- Plasma/Serum: Systemic metabolite profile
- Urine: Waste products and filtered metabolites
- Feces: Gut microbiome and local metabolites
