These pages use inorganic phosphorus measured in serum in the NHANES standard biochemistry profile. Phosphorus participates in bone mineral, cellular energy, and acid-base physiology. The percentiles describe the full US population, not a screened healthy group or a clinical laboratory interval.

Frequently Asked Questions
What form of phosphorus does this page show?
NHANES reports inorganic phosphorus measured in serum. The page uses the conventional laboratory label phosphorus.
How do I convert phosphorus to mmol/L?
Multiply mg/dL by 0.323. For example, 3.7 mg/dL is approximately 1.20 mmol/L.
Are these clinical reference intervals?
No. They are survey-weighted population percentiles from US adults and include participants regardless of health status.
