LECTURE QUIZ
The quantitative immunoglobulin test measures IgG, IgA and IgM. This means the test measures the immunoglobulins made by the body from plasma cells.
Quantitative immunoglobulin tests don't tell if immunoglobulins are functional or non-functional. This means that immunoglobulins tests need to be paired with a SPEP and IFE.
