In the human body, Cryoglobulin can damage organs through increasing blood viscosity or causing immune reactions, Cryoglobulin is also the cause of vasculitis in organs such as kidneys, skin, peripheral nerves. record.

2. Classification of cryoglobulins in blood
According to Brouet's classification, based on the composition of Cryoglobulinemia can be divided into:
Type I: Cryoglobulins will be formed by monoclonal antibodies (usually IgG or IgM, rarely IgA). This form is commonly seen in patients with multiple myeloma, Waldenstrom's syndrome and a number of other diseases... Type II: Mixed cryoglobulin, is the presence of a polyclonal antibody combined with a monoclonal antibody with the Rheumatoid factor activity: 90% have HCV. Type III: Mixed cryoglobulin, at this time, all immunoglobulins are polyclonal antibodies: Often associated with systemic diseases.
