A member asked:
Is a igg quantitative test same as the serum protein electrophoresis test?

Blood tests: They are two different separate blood tests, spep serum protein electrophoresis test is a screening test for plasma cell disorders like mgus, smoldering or full blown myeloma and quantitative igg is a blood test to quantify the amount of igg in blood. Usually more than 3 grams is significant in blood.

It is more specific: A serum protein electrophoresis looks at the levels of all the different proteins in your blood but doesn't identify them. The igg test looks at one of these proteins specifically. Your igg proteins are important for fighting infections and therefore low levels may make you more vulnerable to infection.
