C3d Immune Complexes

Test ID: 


CPT code:



Complement c3d
Complement c3dg
Complement ic3b
Raji cell, Quantitative

Clinical Use:

For the measurement of C3d-bound circulating immune complexes (CIC) present in human plasma or serum.

Additional Test Information:

The importance of circulating immune complexes, and their relationship to various diseases, has been the subject of study for many years. Formation of immune complexes is a protective and usually benign process of a normally functioning immune system. CIC are removed from circulation by a number of complex biochemical, enzymatic, and cellular processes. Key to all of these, however, is the complement system.
