Measures the level of Immunoglobulin M (IgM) in the blood to assess immune response.
Serum IgM is the earliest antibody produced by the immune system when the body encounters a new infection. This test helps evaluate recent infections, immune disorders, and some autoimmune conditions. High IgM generally suggests a recent or active infection, while low IgM may indicate immune deficiency.

How our test process works!
Overview:
Serum IgM test measures the level of Immunoglobulin M (IgM) in the blood. IgM is the first antibody produced by the immune system in response to infection.
Purpose:
-
To evaluate the body’s immune response
-
To check for recent or acute infections
-
To help diagnose immune system disorders
-
To investigate recurrent infections
Risk Assessment :
-
Helps determine presence and stage of infection
-
Used to assess immune function strength
-
Guides treatment in suspected immunodeficiency or autoimmune disease
Normal Range (may vary slightly by lab):
-
Adults: 40 – 230 mg/dL
Interpretation:
-
High IgM:
-
Recent or current infection
-
Autoimmune disorders
-
Liver disease (e.g., cirrhosis)
-
Some blood cancers (e.g., Waldenström’s macroglobulinemia)
-
-
Low IgM:
-
Immunodeficiency conditions
-
Some genetic disorders (e.g., Selective IgM Deficiency)
-
Protein-loss conditions (e.g., nephrotic syndrome)
-
Sample Type:
-
Blood sample taken from a vein
Fasting Required:
-
No fasting needed
Report Delivery Time:
-
Usually 24–48 hours
