Immunoglobulin G (IgG) electrophoresis profile
This test measures the distribution of different types of proteins in your blood, specifically focusing on immunoglobulin G (IgG), which is a key part of your immune system. It helps identify variations in protein levels that may suggest underlying health conditions.
["This test helps assess protein balance and potential immune system or blood disorder risks."]

What This Test Measures
IgG electrophoresis separates blood proteins into bands, showing how much of each protein type (including IgG) is present. This helps detect abnormalities in protein composition, such as elevated or low levels of specific proteins, which may indicate conditions like multiple myeloma, immune deficiencies, or other disorders.
Why It Matters in Your Health
IgG is the most abundant antibody in your blood, providing long-term immunity. Abnormal patterns on this test can signal conditions affecting protein production, immune function, or blood chemistry, guiding further medical evaluation.
Common Conditions Evaluated
This test may be used when doctors suspect conditions like monoclonal gammopathy (unusual protein clumps), chronic infections, or inherited blood disorders. It’s also part of routine protein studies in certain clinical settings.
Sample Collection and Preparation
A blood sample is drawn from a vein, typically in the arm. The blood is processed to separate serum (liquid part of blood) for analysis. No special preparation is needed, but fasting may be advised depending on the clinical context.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical significance of IgG electrophoresis includes identifying monoclonal protein spikes (e.g., in multiple myeloma), evaluating immune system function, or diagnosing conditions affecting protein synthesis or clearance. Abnormal patterns may prompt additional testing or treatment planning.
