BUN (Blood Urea Nitrogen)
BUN (Blood Urea Nitrogen) is a clinical biomarker on the Kidneys panel, reported in mg/dL. Standard reference range: 7–25 mg/dL. Functional (optimal) range used by integrative practitioners: 13–18 mg/dL.
What is BUN (Blood Urea Nitrogen)?
BUN measures the nitrogen component of urea in blood, reflecting protein catabolism and renal clearance efficiency; it is used alongside creatinine to assess kidney function.
Reference ranges
| Range type | Value (mg/dL) | Source |
|---|---|---|
| Standard (lab) | 7–25 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 13–18 | Integrative / functional medicine consensus |
How SomaVue interprets BUN (Blood Urea Nitrogen)
SomaVue maps every result for BUN (Blood Urea Nitrogen) against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
