Where are immunoglobulins produced?
plasma cellsImmunoglobulins, also known as antibodies, are glycoprotein molecules produced by plasma cells (white blood cells). They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.

IgG levels in blood serve as an essential yardstick to guide IVIG therapy. It is also used to assess the effectiveness of the treatment and helps to modify the IVIG course and frequency. Measuring IgG levels at different times to evaluate the peak plasma levels and trough levels can assess response to therapy.
How long does IVIG last?

These conditions, like PIs, require low-dose IVIG therapy to avoid the risk of frequent and deadly infections. Cancers such as B-cell chronic lymphocytic leukemia (B-cell CLL) and multiple myeloma (MM) lead to humoral immunosuppression, and these conditions benefit from IVIG therapy.
