Total IgG antibody load. Persistently high accompanies chronic immune activation. Higher results are the ones to watch. A common adult reference interval is 600–1600 mg/dL.

Standard adult laboratory reference interval. Your own lab's printed range is the one that applies to your result.

What commonly moves it

  • Plasma-cell / paraprotein activityClonal light-chain production raises globulin and can suppress marrow output.
  • Systemic inflammationRaises hepcidin (blocking iron), ESR/fibrinogen, and blunts T3 conversion.
