Match the types of cryoglobulin with the correct description.

-Type I

Accepted Answer

A)  Mixed cryoglobulins in which both constituent immunoglobulins are polyclonal.More than 90% contain IgM rheumatoid factor and IgG.These cryoglobulins are seen in a variety of autoimmune,systemic rheumatic diseases and persistent infections with immune complexes (e.g. ,bacterial endocarditis) .
