A cryoglobulins test is used to help detect the presence and relative quantity of cryoglobulins in the blood. It may be ordered along with other tests to help determine or rule out potential causes of cryoglobulinemia. The tests ordered depend on what condition or disease is suspected.
If the cryoglobulin test is positive, then it will be followed with protein electrophoresis and immunofixation electrophoresis (IFE) testing to determine which type(s) of protein are present as cryoglobulins and which type of cryoglobulinemia the person has.
The cryoglobulins test is negative (no cryoglobulins found) in most healthy people and is not routinely ordered for those without symptoms.
When the test is positive, it means that cryoglobulins are present and have the potential to precipitate upon exposure to cold. The symptoms experienced when this happens will vary from person to person, may be different with each exposure, and will not necessarily correlate with the quantity of cryoglobulins present.
A positive test for cryoglobulins may be seen in numerous conditions.
