    Abstract: The present invention provides a method for the precipitation of cryoglobulins. In general, the method comprises the steps of: (a) providing a cryoglobulin sample; (b) providing a reagent such as a buffer reagent for decreasing the ionic strength of the sample; (c) combining the cryoglobulin sample with the buffer reagent to decrease the ionic strength of the test sample and produce a test sample; (d) chilling the test sample to form a cryoblobulin precipitate in said test sample; and then, optionally but preferably, (e) centrifuging the test sample to separate the cryoglobulin precipitate from said test sample. Tests kits useful for carrying out such methods are also provided.
