Why is the Test Performed?
This test is used to roughly measure the amounts of various immunoglobulins in urine. Most often, this is used as a screening test, particularly in people who have protein in the urine (demonstrated on urinalysis or other test) when urine protein electrophoresis indicates a significant amount of globulin proteins (antibodies).
