Total serum protein is measured by the biuret method and includes albumin plus globulins. These percentiles describe the full US adult population by age and sex, not a screened healthy group or a clinical laboratory interval.

Frequently Asked Questions
What contributes to total protein?
Total protein combines albumin with the group of proteins reported as globulins.
How do I convert g/dL to g/L?
Multiply by 10. For example, 7.3 g/dL is 73 g/L.
Are these clinical reference intervals?
No. They are survey-weighted population percentiles from US adults and are not laboratory decision limits.
