NHANES calculates globulin as total protein minus albumin in the standard biochemistry profile. It represents a grouped non-albumin protein fraction rather than one specific protein. These values are population percentiles, not clinical laboratory intervals.

Frequently Asked Questions
Is globulin measured directly?
No. In this NHANES file, globulin is calculated as total protein minus albumin.
How do I convert g/dL to g/L?
Multiply by 10. For example, 3.1 g/dL is 31 g/L.
Does globulin refer to one protein?
No. It groups multiple non-albumin serum proteins into one calculated chemistry value.
