At a Glance

Why Get Tested?

To help evaluate a person's immune system status; to detect and monitor an excess or deficiency in one or more of the immunoglobulin classes (IgG, IgA, and IgM)

When to Get Tested?

When you have recurrent infections and/or chronic diarrhoea; when your healthcare professional suspects an immunoglobulin deficiency; periodically to monitor a condition that affects immunoglobulin levels that may be genetic or acquired (HIV/AIDS, multiple myeloma), as part of the investigation of anaemia and bone pain with raised ESR (multiple myeloma, Waldenstrom’s macroglobulinaemia).

Sample Required?

A blood sample drawn from a vein in your arm; sometimes a cerebrospinal fluid (CSF) or saliva sample
