Quantitative Immunoglobulins - Nephelometry
Definition
Nephelometry is a laboratory technique used to obtain a measurement of the amount of IgM, IgG, and IgA immunoglobulins accurately and rapidly.
The test uses a specialized instrument to measure the movement of particles in a solution (turbidity) caused by the interaction of immunoglobulins in the serum and anti-immunoglobulin that has been added to the serum.

Why is the Test Performed?
The test provides a rapid and accurate measurement of the amounts of immunoglobulins M, G, and A. (Immunoglobulin D has no known clinical significance, and IgE must be measured by more sensitive techniques such as radioimmunoassay or enzyme-linked immunoassay.)
