Beta Globulin optimal range and reference range

Compiled by Alina Radu, founder of Sera, from the published sources below · Last reviewed November 9, 2026

Sera's bands for Beta Globulin:

Optimal 0.7 – 1.2 g/dL (7 – 12 g/L); out of range below 0.7 or above 1.2 g/dL.

Evidence grade: Published reference interval. A band that primarily reflects a published adult laboratory or population reference interval. It is not necessarily applicable to every assay or laboratory.

All units

Unit	Optimal	Sufficient	Out of range
g/dL	0.7 – 1.2	—	below 0.7 or above 1.2
g/L	7 – 12	—	below 7 or above 12

No separate Sufficient band is currently defined for this marker.

What the evidence says

Read against iron studies first: transferrin sits in this fraction and rises in iron deficiency, which is the commonest cause of a raised beta. Some laboratories split beta-1 and beta-2, and those figures are not interchangeable with a combined one. The lower edge of 0.7 g/dL (7 g/L) is Labcorp's. The upper edge of 1.2 g/dL falls between published limits: MedlinePlus, ARUP and the University of Iowa end at 1.1 and Labcorp at 1.3, so read a result of 1.1 to 1.3 against the report's own range.

Assay: Results differ meaningfully between platforms and methods. Compare against the interval printed by the issuing laboratory before acting on a borderline value.

What Beta Globulin measures

The beta fraction from serum protein electrophoresis, chiefly transferrin, complement components and beta-lipoproteins.

Read it against iron studies before anything else: transferrin rises in iron deficiency, and that is the commonest reason for a raised beta fraction. Some laboratories report beta-1 and beta-2 separately, in which case the two are not interchangeable with this combined figure.
