Cryoglobulin is an abnormal serum protein which precipitates or gels on cooling. Small quantities of cryoglobulin have been found in the sera of patients with many disparate diseases,¹ including subacute bacterial endocarditis, hepatic cirrhosis, blood dyscrasias, and the collagen diseases, but clinically significant amounts of cryoglobulin occur in only two conditions: multiple myeloma and "essential" cryoglobulinemia.

In the test tube the serum from a cryoglobulinemic patient will show a flocculent white precipitate or opaque gelification when the temperature is reduced to 5 C. The rapidity of the solidification is proportional to the concentration of cryoglobulin and is graded from 1+ to 3+ on this basis. At cryoglobulin concentrations of 25 mg. per 100 cc. and over (3+), precipitation occurs immediately on chilling and may occur before the serum is cooled to below room temperature.¹ Repeated cooling and warming of cryoglobulinemic serum results in the eventual loss of the . . .
