the presence of cryoglobulin in the blood, associated with a variety of clinical manifestations including Raynaud's phenomenon, vascular purpura, cold urticaria, necrosis of extremities, bleeding disorders, vasculitis, arthralgia, neurologic manifestations, hepatosplenomegaly, and glomerulonephritis.
The presence of abnormal quantities of cryoglobulin in the blood plasma.
cryoglobulinemia/cryo·glob·u·lin·emia/ (-glob″u-lin-e´me-ah) the presence in the blood of cryoglobulin,which is precipitated in the microvasculature on exposure to cold.

the presence of cryoglobulins in the blood. Presence of cryoglobulins may be associated with a variety of clinical disorders including Waldenström's macroglobulinemia, hepatitis C, multiple myeloma, and leukemia.
cryoglobulinemiaPrimary cryoglobulinemia Hematology A condition caused by proteins that precipitate in vivo on cooling of acral parts, which are often associated with immune complex-related disease; cryoglobulinemia has been divided into 3 clinical forms Clinical Pain, cyanosis, arthralgias, vascular purpuras, cold intolerance, HTN, CHF Lab ↓ C4 and other complement proteins
Type I Monoclonal cryoglobulinemia Underlying disease is often malignant; IgG (malignant myeloma), IgM macroglobulinemia or lymphoma/CLL, rarely others (eg IgA nephropathy), benign monoclonal gammopathy
Type II Poly-monoclonal cryoglobulinemia A complex of immunoglobulins, eg mixed IgM-IgG, G-G, A-G or other combinations that may be associated with lymphoreticular disease or connective tissue disease (rheumatoid arthritis, Sjögren syndrome, mixed essential cryoglobulinemia)
Type III Mixed polyclonal-polyclonal cryoglobulinemia Mixed IgG & IgM, ± IgA, due to rheumatoid arthritis, SLE, Sjögren syndrome, EBV, CMV, subacute bacterial infections, poststreptococcal, crescentic and membranoproliferative glomerulonephritides, DM, chronic hepatitis, biliary cirrhosis
The presence of abnormal quantities of cryoglobulin in blood plasma.
Condition in which protein in the blood forms particles in the cold, blocking blood vessels and leading to pain and numbness of the extremities.
the presence of cryoglobulin in the blood, which is precipitated in the microvasculature upon exposure to cold.
