Gamma Globulin
- Sample Type
- Standard
- Fasting
- No
- Unit
- g/dL
Gamma globulins represent the fraction of serum proteins that primarily contain immunoglobulins (IgG, IgA, IgM, IgD, IgE). In Serum Protein Electrophoresis, this region is scrutinized for 'M-spikes' (monoclonal spikes), which indicate the overproduction of a single antibody by a clonal population of plasma cells. Evaluation of this component is critical for diagnosing multiple myeloma, Waldenström macroglobulinemia, and chronic inflammatory states.

Why Context Matters
Recent vaccinations, acute infections, or chronic liver disease can cause polyclonal increases in gamma globulins that may mimic early-stage plasma cell disorders. Additionally, some rare monoclonal proteins may migrate in the Beta region rather than the Gamma region.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
