What is cryoglobulinemia?

Cryoglobulins are proteins found in the blood that precipitate (clump together) in the cold and may cause inflammation and organ damage. However, these proteins can also be present in low levels in the blood without causing any symptoms. When there are symptoms due to the cryoglobulins, the disease (usually a special rash) is called "cryoglobulinemia."
